(Anonymous Gaddiano, 1542)



 Youth (1452-1481) The origins and family   

The birthplace of Leonardo Anchiano (village of Vinci).
Leonardo was the eldest son of twenty-five notary Ser Piero da Vinci,
of wealthy family,           
had a relationship with a certain Caterina illegal extraction below.
The news of the birth of their first grandchild was noted by his                             

                         grandfather Antonio, father of Piero himself   notary, 
                     of an ancient book notary fourteenth century, used now as a  

                          collection of "recollections" of the family, stating:
                        "He was born a grandson, son of Ser Piero my son to 

                        day 15 April to Saturday at 3 o'clock at night (actual 22.30). 
                          He was named Leonardo. 
Battizzollo priest Piero di Bartolomeo da Vinci, in the presence of:
"Daddy Nanni, Tonino Meo, Pier Malvolto, Nanni di Venzo, Arigo John German,
Mona Lisa by Dominic Breton, Monna Antonia Giuliano, Monna Niccolosa of Barna, Monna Maria,
daughter of Nanni di Venzo, Monna Previcone of Pippa. "
The register does not specify the birthplace of Leonardo, who are widely believed to be the home
that the family of Ser Piero had, along with a farm in Anchiano,
where Leonardo's mother will live.
The baptism took place in the nearby parish church of Santa Croce,

 but both the father and the mother were absent,             
not as inconveniently married.
Piero had been preparing well for other wedding, while Catherine was tried, in 1453,
a husband who accept willingly compromised his situation, finding a farmer's field Zeppi,

 near Vinci, that of Piero da Vinci Vaccha, said Attaccabriga, maybe even hired as

 his brother Andrew.
Meanwhile, back in 1452, his father Piero had married John Albiera Amadori, from which they will have children.
The joyful reception of the child, despite its illegal status, is demonstrated,
as well as from the record of his grandfather, but his presence in the family home of Vinci.
This is stated in the declaration for the land of Vinci year 1457, prepared always by his grandfather Antonio, where it is stated that the said Antonio was 85 years old and lived in the parish

of Santa Croce, husband of Lucy, aged 64, and had for his sons Francesco and Piero, aged 30, married to Albiera, twenty-one, and their partner was "Leonardo son of Ser Piero said illegitimate

 born of him and Chaterina that this is the woman Achattabriga Piero da Vinci Vacca, aged 56. '
The stepmother Albiera died at twenty-eight in 1464, when the family lived already in Florence,
being buried in San Biagio. Ser Piero married three times:
a second (1464) with fifteen Francesca di Ser Giuliano Manfredini, who also died without offspring,
a third with Margherita di Francesco di Jacopo di Guglielmo (1475),

who finally gave him six children;
another six was the fourth and last marriage.
Leonardo had so twelve of half brothers and sisters, all much younger than him
(The last was born when Leonardo was forty years old), with whom he had a few relationships,
but that gave him a lot of problems after the death of his father in the struggle of inheritance.

           Training period         

Ser Piero had already worked in Florence and in 1462, as a matter of Vasari, he returned with his family, including the little Leonardo.
The father would show his friend Piero Andrea del Verrocchio some drawings of this bill
would convince the teacher to take Leonardo in his workshop;
in reality it is unlikely that an apprenticeship started just ten years,
that the entry of Leonardo in Verrocchio's workshop is now considered back.
It is thought that Leonardo remained in the country in the grandparents' house,

where he took his education, rather messy and uneven, with no programming background,

by the grandfather Antonio, Uncle Piero Francesco and the priest who had baptized.
In fact, the child learned to write with his left and down, in a very mirror image of normal writing.
Vasari remembered as the guy in the studio began "many things and then abandoned,"
and now unable to start the legal career, his father decided to introduce it to the knowledge

of the abacus, although "moving constantly doubts and difficulties to the master who taught him,

 right [that] often confused him."

              The arrival in Florence         

The grandfather died ninety-six in 1468, citing the inheritance "Leonardo", together with the grandmother Lucia, his father Piero, the new stepmother Francesca Lanfredini,

 and uncles Francesco and Alessandra.
The following year the family of his father, became notary of the Signoria of Florence,

along with his uncle Francis, who was enrolled in the Silk Road, was domiciled in a

Florentine home, which was demolished as early as
the sixteenth century, in via dei Gondi, next to Piazza della Signoria.


      In the workshop of Verrocchio       

Landscape with River (1473) now becoming more and more evident the interest of the young Leonardo in "draw et the doing of relief, as things that gl'andavano to fantasy more than anything else,"
Ser Piero finally sent his son, in 1469 or 1470, in the workshop of Andrea del Verrocchio,
which in those years was one of the most important monuments of Florence,
as well as a real breeding ground for new talent.
Among the students included names that would become the great teachers of the next generation,
such as Sandro Botticelli, Pietro Perugino, Domenico Ghirlandaio, and Lorenzo di Credi,
and shop espletava multifaceted activity, from painting to sculpture techniques
(Stone, lost wax casting and wood carving), to the "minor" arts.
Above all, it stimulated the practice of drawing, bringing all employees in a language almost

common and even today can be very difficult to attribute the works outputs from the workshop
the hand of the master or to a specific student.
We know many examples of drawings of drapery out of his shop, which come from exercises

that the teacher did do so by copying the folds of tissue placed on models of the earth.
In addition, the students learned the concepts of carpentry, mechanics,

engineering and architecture.
Leonardo is mentioned in the Compagnia di San Luca, of Florentine painters, in 1472:
"Lyonardo di ser Piero da Vinci painter de 'give all june 1472 only. six for the grace made
each had its debt coll'Arte to say even until July 1, 1472 and de 'give all November 1472 only. 5
for his mail made day 18 octobre 1472. "
This means that at that time was recognized as independent painter,
whose formative experience could be closed, although his collaboration with Verrocchio be

 protracted for several years.
On August 5, 1473 Leonardo dated the first certain work, Landscape with river, a design

 with a view bird's eye view of the Arno valley, now in the Cabinet of Drawings and

Prints of the Uffizi.
The focus on a true description of the natural world was a constant feature of Leonardo,
especially evident in the juvenile stage.
This earned him the award of certain works contributions to outputs from the workshop of

Verrocchio, as Archangel Raphael and Tobias (London, National Gallery),

 in which the realistic fish or scaliness the energy snappy of the dog have been proposed

as details leonardeschi, even if it is attributions not universally shared.
The same applies to the landscape of the Madonna and Child with Angels (also in London),

 with a rocky just remind the Landscape with river.
Bears witness to the confrontation with the master of the Baptism of Christ Uffizi, painted with

several coats.
According to the indication of Vasari, later confirmed also by modern critics, is to be assigned to Leonardo The angel in the left foreground and the soft landscape background, as well as

 the general organization of the style to mix at least three coats of different personalities

 (Verrocchio, a very gifted student and Leonardo himself).
In this work are already evident a few reasons the style of Leonardo, which exceed the limits of the teachings workshop: the decoration based on flowing reasons, attention to the elements plants or expressiveness of the faces, often portrayed with an ambiguous smile;
New is also the spatial rendering and Atmospheric unified, and the first hints of a style faded.
Also according to Vasari, Leonardo's skill in the proof of Baptism would push Verrocchio,
reluctant to make a direct comparison was starting to see him losing to devote

himself exclusively to sculpture.
In fact, the story is rejected by modern critics, inclined to think it an emphasis arbitrary
the literary theme of '"student becomes the master" brought about by the historic Arezzo.

    Leonardo sculptor   

Vasari also remembered how Leonardo worked "in sculpture, doing, in his youth,
ground some heads of females laughing, going, formed by the art of chalk, and likewise the

 heads of cherubs, that seemed to come out of the hand of a master. "
You do not know, however, no safe sculptural work of Leonardo, despite various proposals attributive
advanced in the past.
Recently Parronchi Alessandro gave him a bust of cupid, in a private collection in Florence.
There are many coincidences, however, also very strict, including some drawings or sketches
Leonardo and Verrocchio's sculptures, such as profile former captain (1475,
London, British Museum), similar to the carved reliefs of ancient Captains for Matthias Corvinus,
or the Study of hands (1475, Windsor, Royal Library), considered a study for the portrait of

Ginevra de 'Benci and very similar to the position of the hands of the bust of Lady with a bouquet.
In the end the only experiment safely with the sculpture of Leonardo was the unfinished

monument to Francesco Sforza.

      First independent works       

Dreyfus Madonna (1469 approx)
The first independent works of Leonardo are now dated between 1469 and the early seventies,
even before Baptism.
In these works, of which the critical debate was very heated, the artist shows strong

adhesion to the language common students of Verrocchio, complicating studies of attribution.
The full authenticity of the little Madonna Dreyfus

(1469 or so, the National Gallery of Art, Washington)
is a finding of recent criticism, which in the past had swung even the names of
Verrocchio and Lorenzo di Credi:
is in fact close proximity with the subsequent stylistic


       Madonna del Garofano (1473) circa, Alte Pinakothek, Monaco)

with delicate and almost transparent skin tones, gestures family between

mother and child, the setting on a dark background in which there are

"Flemish" two windows on a bright landscape.
It comes from the workshop of Verrocchio contemporary

Annunciation in the Uffizi, but his paternity, even if it can be considered

of only hand,  has long been disputed by critics, to finally settle on the

                        name of Leonardo.
The fact Announcing Angel appears next to the invoice of the angel of Baptism,
and there are two designs some of Leonardo:
one study arm at Christ Church, Oxford, and a Study of drapery with the legs of the

Madonna in the Louvre, that make specific reference, respectively, to the

                         Archangel and Our Lady.
Although it is forming a personal style, appear still reasons Verrocchio,
lectern-like altar with lion's paws, which are reminiscent of the Tomb of Giovanni

and Piero de 'Medici.
The painting contains a "mistake" in perspective, in the right arm of the Virgin too long,
defect that is attenuated by assuming a point of view slightly to the right of the work.



      La Madonna del Garofano (1475-1480)        

already clearly shows a rapid maturation of the style of the artist,               
directed to a greater fusion between the various elements of the image, with
transitions bright and dark and light areas most sensitive and fluids;
the Virgin fact emerges from a dark room contrast with the distant and fantastic landscape that appears two-light windows in the background.
In 1474 to 1478 was the portrait of a woman in Washington, identified with

 Ginevra de 'Benci
This explains the juniper painting behind him.
This is the daughter of a prominent Florentine merchant, which demonstrates that

Leonardo had access to commissions from the rich Florentine bourgeoisie.
The work shows more clearly the influence of Flemish art, in the luminescence of the hair,
in attention to the light output by the color.
There is, however, also the characteristic rendering of atmospheric character in the

foreground and the landscape, in addition to the technique of blurring with the fingertips colors, especially in the realistic skin.

  Four years of silence    

From January 1474 to autumn 1478 you do not know the works of Leonardo.
This silence is particularly odd when you consider how in the years immediately preceding
Leonardo's career finally taking off them, backed by a wealthy and influential father,
who kept it until at least 1480 and that could certainly help in obtaining commissions.
It is assumed, therefore, that in his early twenties Leonardo was still uncertain about their future,
closer to the world of science with the attendance of the elderly geographer and astronomer
Paolo dal Pozzo Toscanelli.
Probably had the opportunity to investigate the anatomy witnessing the dissection of corpses
morgues in hospitals, but also had to study the physics and mechanics through direct experiments.
The April 8, 1476 was filed an anonymous complaint to the officers at night and de 'monasteries against several people, including Leonardo, sodomy consumed to the seventeen year old Jacopo Saltarelli, a resident in via Vacchereccia
(Next to Piazza della Signoria).
Although there was in Florence at a certain tolerance toward homosexuality,
the penalty in these cases was very strict:
castration for sodomites adults and mutilation of a foot or hand for young people.
In addition to Leonardo, among others investigated were the goldsmith Bartolomeo di Pasquino,
the tailor, (tailor) Baccino, residing at Via de 'Cimatori at Orsanmichele,
and especially Leonardo Tornabuoni which is noted as dressed in "black"
(The fabric more expensive, the prerogative of high society):
for he was a young scion of the powerful family related to the Medici.
A similar complaint was also filed in June of the same year.
It was the involvement of the Tornabuoni that would play in favor of the accused:
In fact, the accusation was filed and the defendants were all "absoluti cum conditione retumburentur ut", "forgiven (Or released) unless there is no other complaints about it. "
The report shows how Leonardo, however, at that time was still apprenticed to Verrocchio.

    The return to painting   

On 10 January 1478 he received the first public office, an altarpiece for the chapel of
St Bernard in the Palazzo della Signoria;
grossed by the Priors 25 florins but perhaps not even started the job, then given in 1483 by

Domenico Ghirlandaio and then to Filippino Lippi, who completed it in 1485 (the Altar of Eight,

 now in the Uffizi).
In this shovel the expression "Leonardo", that is ambiguously smiling
Madonna had in the past confused some critics who had attributed to Leonardo.
Meanwhile, the desire to devote himself to painting had to return to bite,
as evidenced by a note, partially incomplete, in which the artist recalls how at the end of 1478
began two Madonnas.
One of these is recognized in

         Madonna Benois,    

Today the Hermitage in St. Petersburg,
that Bocchi in 1591 mentioned in the Florentine house of Matthew and John Botti:
"Tablet colored in oil by Leonardo da Vinci, excessive beauty,
where he painted a Madonna with the greatest artifice et with due diligence,

the figure of Christ, that child is beautiful to a marvel:
seen a raise in the face of unusual et admirable work difficulty in attitude with

                happy   ease ";
          But that description may refer  also to the Madonna of Carnation.
Yet to be dated around 1475-1478 the small Annunciation in the Louvre,
probably part of the predella of the Madonna and Child with Saints by

Lorenzo di Credi of the Cathedral of Pistoia, that would include also the Birth of the Child by Perugino, hours at the Art Gallery in Liverpool and San Donato

and the tax collector of the same Lorenzo, hours at the Art Museum in Worcester.

 The unit of composition, consistency and individuality of the small table, but back away from the Annunciation in Florence, confirm the attribution to

Leonardo agree.
Meanwhile, at least since 1479 was no longer living in the household of his father Piero,
as evidenced by a document of Florentine land register.

                      The approach to the Medici              

Design of the body of Bernardo Bandini (1479)
In these years was probably also the approach to Lorenzo the Magnificent and his circle,
which was part of his master Verrocchio.
Some studies show Da Vinci code sheets for military advice and engineering
probably required by Lorenzo. The December 29, 1479
Leonardo drew the corpse hanging from one of the leaders of the conspiracy of the Pazzi,
Bernardo Bandini Baroncelli (the murderess of Giuliano de 'Medici), confirming a link with

 the Medici family.
This is a drawing of hanged, with annotations, conserved at the Musée Bonnat in Bayonne.
The Anonymous Gaddiano also recalls his attendance, around 1480,

the Garden of San Marco, a sort of open-air museum where it was exposed to the collection

of ancient statues of Physicians and the elderly sculptor Bertoldo di Giovanni

held an art school which also participated, almost ten years later,
the young Michelangelo Buonarroti. The note reads:
"Stood [... Leonardo] with the Magnificent Lorenzo et, giving them salary for himself,
did the work in the garden on the square of San Marco in Florence »:
the purchase of land by Lorenzo was that year and therefore had to Leonardo
eseguirvi works of sculpture and restoration.


  The Adoration of the Magi        

If the unfinished Saint Jerome of the Vatican Pinacoteca do not have any documentary evidence, Adoration of the Magi, now in the Uffizi, you know that he

 was commissioned in March 1481 by the monks of San Donato a Scopeto
as an altar piece, to be made within thirty months;
committee, the most important received from Leonardo until then,

was probably facilitated by the father Ser Piero, who was a notary for monks.
Leonardo, however, did not hand never work and only fifteen years after it was 

             replaced with

 a painting of the same subject, by Filippino Lippi.
The work, which remained a sketch in brown heightened with white lead, was left by

leaving for Milan, his friend Amerigo Benci, the father of Geneva, in 1482.
In it, Leonardo began to reflect more deeply on the subject, so frequent in Florentine

art of the fifteenth century, emphasizing the time of '"Epiphany" in the original greek meaning of "event". Baby Jesus reveals his divine nature in fact surprising the audience.
"Nothing remains traditional Epiphany, and the shepherds and kings have replaced the broader multitude of hands, faces intensely characterized, darting from one side of the clothes out of the shadows of the hedge human sucked the other suspended by a luminous dust.
Are not magicians, they are guardians of herds:
are living creatures, all creatures with faith and with doubt,
with the passions and the renunciation of life, haloed by the light-creating this masterpiece
in which the color would not take place "(Angela Ottino).


      In Milano (1482-1500) The departure      

Between the spring and summer of 1482, Leonardo was already in Milan, one of the few cities in Europe to exceed one hundred thousand inhabitants, in the center of a region populated and productive.
The reasons for his departure from Florence are varied.
Surely, as evidenced by the Anonymous Gaddiano and Vasari, sending the artist was caused by Lorenzo il Magnifico
as part of its diplomatic policies with the Italian dominions, where the Florentine masters were sent
as "ambassadors" of the artistic and cultural dominance of Florence.

Our brothers and Antonio da Majano Rossellino
had left for Naples and a group of painters had started to decorate the new papal chapel

 of Sixtus IV.
Leonardo had a mission to bring the Duke Ludovico il Moro homage. The Anonymous wrote:
"Leonardo was thirty years that the said Lorenzo the Magnificent was sent to

the Duke of Milan to present Improved Atalante along with a penny, that one was playing this instrument. "
Vasari tells that he was a great musician and had built this silver lyre,
partly in the shape of a horse's head, "what strange and new, to the end because the harmony was more tuba and more resonant voice. "
Arrived, Leonardo took part in a musical contest with that instrument called the Sforza court,
"Wherefore surpassed all the musicians who were there to sound contests."
At that time Leonardo wrote a famous "point of use" of nine paragraphs,
in which he described his first projects of engineering, military equipment,
of hydraulic engineering, architecture, and only at the end of painting and sculpture,
to be covered in time of peace, including the design of a bronze horse for a monument to

Francesco Sforza.
It is clear that Leonardo was determined to stay in Milan
city ​​that was to fascinate him for his openness to new scientific and technological
caused by the continuing military campaigns.
The Florentine ambience in fact had to get him some discomfort now:
on the one hand it should not be recognized in the culture of the Neoplatonic Medici circle,
so imbued with philosophical and literary influences, he described himself as "man without letters";
the other, his art was diverging more and more from linearity and the search for a rarefied beauty
and idealized dominant artists on the scene, already his companions in the workshop of Verrocchio,
such as Perugino, Ghirlandaio and Botticelli.
After his exclusion from the fresco of the Sistine Chapel remarked that it was not in that group.


               The Virgin of the Rocks    

Virgin of the Rocks (first version, 1486), detail, Paris, LouvreI documents
seem to indicate that the reception of Leonardo in the Milan was rather lukewarm,

not getting initially the desired results in his famous letter to the Duke.
The artist also had a number of difficulties with the language spoken by the people
(At the time the Italian language as a "Tuscan medium" did not exist,

 everyone spoke only their own dialect),
although experts find themselves later in his writings the following years even

To initially commissioned the artist had in fact wait for April 25, 1483,

 when Bartholomew Scorione, prior of the Milanese Confraternity of the Immaculate Conception, entered into a contract for a shovel to be placed on the altar of the

chapel of the Confraternity of the church of San Francesco Grande (now destroyed).
The contract also attended the Evangelist and John the painter brothers Ambrogio De Predis, that housed Leonard in their home near Porta Ticinese.
This is the altarpiece of the Virgin of the Rocks, which, according to the very detailed contract, was to be the central compartment of a triptych.
The central panel was supposed to be a Madonna and Child with two angels and prophets,
the other two, four angels, singers and musicians, then painted by De Predis;
the decoration was to be rich, with abundant gilding and the work was to be delivered

 by 8 December for a total fee of 800 pounds to be paid in installments until February 1485.
Leonardo, despite the narrowness of the terms of the contract, interpreted the iconographic

 program in an original, depicting the scene of the legendary meeting between

St. John and the baby Jesus in the desert, and concealing references to the

Immaculate Conception in the arid rocky background and the way in which
Madonna will blend through a ravine that seems to evoke the mystery connected with

 maternity. In a petition to Ludovico il Moro, dating from 1493, which shows that the work

had been carried out at least by 1490 - but the critics still consider it finished by 1486 -

Leonardo and Ambrogio De Predis (Evangelista died at the end of 1490 or early 1491)

demanded a compensation of 1,200 pounds, rejected by his brothers.
The litigation dragged on until April 27, 1506, when the experts stated that the board

 was incomplete and, established two years to finish the job, granted a compensation

of 200 pounds; October 23, 1508 Ambrose cashed the last installment and Leonardo ratified the payment.
Leonardo appears, given the non-payment of 1,200 lire to the Brotherhood,
had sold for 400 pounds the table, now in the Louvre, to the king of France, Louis XII,

providing, during litigation, a second version of the Virgin of the Rocks,
which remained in San Francesco Grande until the dissolution of the Brotherhood in 1781

and is now preserved the National Gallery in London, along with the two tablets of the De Predis.
It must be said that not all the copy of London's Leonardo:
for some, such as Carlo Pedretti, although drafted by the teacher, was conducted with the help

 of students;
that can be addressed Ambrogio de 'Predis to complete the work is plausible.
Giulio Carlo Argan shows that for all Leonardo is "immanence."
He looks at the reality and nature through the eyes of a scientist.
The landscape of this "is not a landscape seen nor a fantastic landscape:
is the image of nature naturans of themselves and get rid of cyclic transfer of matter

 from the solid state, to the liquid, all'atmosferico:
the figure is no longer the opposite of nature, but the deadline of its continuous evolution. "

   In the circle of the (Ludovico Maria Sforza)  

Belle Ferronnière (1490–1495), Parigi, Louvre 

In the early years in Milan Leonardo continued with his studies in mechanical engineering, inventions of military machines, the development of various technologies. In 1485 must have been entered in the
circle of Ludovico il Moro, for whom he designed with versatility irrigation systems,

he painted portraits, approntò designs for court festivities, etc..
A letter to remember those years, however, as the artist was dissatisfied with the
fees received, and tells his family was at the time.
He wrote Leonardo to the Duke in three years had received

 only fifty ducats, too few to feed "six mouths"
it was her, than those of the three students Marco d'Oggiono,
John Boltraffio and Gian Giacomo Caprotti said Salai, a laborer and, since 1493,
a maid named Catherine, perhaps the mother of Leonardo in the wake of his son after
be widowed. Salai, by Oren, at the service of Leonardo in 1490, when he was ten,

 he had his nickname by one heck of Morgante of Pulci:
Leonardo's assistant then called "thief, liar, stubborn, greedy," but always treated him

On completion of the Virgin of the Rocks Leonardo must engage in some Madonnas.
One was probably the d '"optimo painter" to be sent as a gift to King Matthias

Corvinus of Hungary in 1485
(Described as a "figure of Our Lady, how beautiful excelente et devotional Sapia more to do,
sparagno without spending any "in a letter dated April 13, 1485 Duke).
Another was probably the Madonna Litta, performed mostly by assistants,
especially Boltraffio and Marco d'Oggiono.
Another recurring theme is the portrait of the Milanese period, in which the artist was able to

capitalize on the anatomical studies
started in Florence, dealing especially the links between the faces and the

 "movements of the soul"
that is, the psychological and moral qualities that transpired on time by the appearance.
One of the first tests of this theme that has survived is the Portrait of a Musician,
perhaps the master of the Chapel of the Milan Cathedral Franchino Gaffurio.
Noteworthy are in this analytic attention and the psychological aspect in the eyes elusive

Another famous portrait of this period is the so-called Belle Ferronnière, a lady,
perhaps related to the Sforza court, with an intense look that aristocratically avoid the

 gaze of the viewer.
Certainly related to the ducal patronage is the Portrait of Cecilia Gallerani, said


la Dama con l'ermellino.   

         La presenza dell'animale, oltre a richiamare il cognome della donna

              (galé in greco),
alludeva anche all'onorificenza dell'Ordine dell'Ermellino,
ricevuta proprio nel 1488 dal Moro da parte di Ferrante d'Aragona.

 The marriage of Gian Galeazzo Sforza and Isabella of Aragon   

For two years after the ducal commissions became more and more frequent.
Received such payments for the project of the lantern of Milan Cathedral.
In early 1489 took care of the decorations, the Castello Sforzesco,
for the marriage of Gian Galeazzo Sforza and Isabella of Aragon, quickly suspended the
death of the mother of the bride, Ippolita d'Aragona, and sent back the following year,
as Leonardo wrote the book titled of the human figure.
The festivities resumed only January 13, 1490, for they, like the poet Bernardo Bellincioni in 1493,
"There was building, with great ingenuity and art to master Leonardo da Vinci in Florence,
heaven with all the seven planets (seven, because the moon was considered a planet)
going around and the planets were represented by homini. "
Another document, written shortly after the celebration and preserved in the Biblioteca Estense

in Modena, recalls the thrill of staging, the audience, the actors and the splendor of the dresses
"El Paradiso was de facto similarity half an egg, and which side was in tottu made ​​horo,
with the greatest number of lights ricontro the stars, with some fools where he was the

seven planets, segondo and their degree highs and lows. A back of the rim above the finger mezo round was there significant XII, with certain lights inside the'll see that they made a gallant et pretty sight:
in which Heaven had many songs soni et et suavi very sweet. "Heaven" invented by Leonardo,
taking advantage of the long tradition of sacred representations Florentine had to be full of

special effects, light effects and sounds, which remained for a long live in the memory of his contemporaries.

 The equestrian monument to Francesco Sforza    

In those years, Leonardo began the grand plan for an equestrian monument to Francesco Sforza,
as evidenced by a payment by way of advance on costs for a model,
paid on behalf of the Duke by the Superintendent of the Treasury of the court, Marquis Stanga.
On 22 July 1489, also Pietro Alamanni communicated to Lorenzo the Magnificent Ludovico

 request to obtain the co-founders of Florentine bronze:
"A master or two APTI to this work et although the Have made ​​this thing in Leonardo da Vinci,
I do not think much know the lead. "
The company was huge, not only for the size of the statue, which was to be cast in bronze,
but also for the purpose of sculpting a horse in the act of rearing up and fall on the enemy.
The artist spending months on the study of horses, attending the ducal stables
to look closely at the anatomy of these animals, especially with respect to the relaxation
and the tension of the muscles during the action.
The company was suspended to resume the celebrations marriage-Sforza d'Aragona.

A Pavia      

On 21 June 1490 he went to Italy, at the request of the Cathedral fabbricieri for advice.
He went there with Francesco di Giorgio Martini, an architect and author of the Treatise on Architecture, incorporating the De Architectura of Vitruvius.
Leonardo had to find particularly challenging in the reworking of the vulgar Latin text,
depth study of architecture:
of those years is in fact the so-called Manuscript B (Paris, Institut de France),

dedicated to planning, religious and military architecture.
Date from the same period in the studies on the human body and its perfect proportions,
which culminated in the execution of the famous drawing of the Vitruvian Man.

     The merger of the colossus  

Back in Milan is dedicated to various activities, including celebrations for the wedding of
Anna Maria Sforza and Alfonso I d'Este (1491) and those of Ludovico il Moro and

Beatrice d'Este (1494).
Slowly brought forward the project of an equestrian monument to Francesco Sforza,

Ludovico il Moro wanted to dedicate to the memory of his father.
The project went through several versions was of colossal dimensions,
coming, in 1491, the final phase of implementation of the final model
(in wax and then clay) and waited for the next lost wax casting of bronze.
The company had extremely difficult, to the great need of molten bronze to be paid,
for this, he dedicated himself to meticulous calculations at the design stage.
Meanwhile, in 1493, was for a while in the wake of the procession that accompanied

Germany Bianca Maria Sforza, wife of Emperor Maximilian of Hapsburg;
he went to Lake Como

(where he studied the famous intermittent source at the villa Pliniana Torno)
visited the Valsassina, Valtellina and Chiavenna.
Back in Milan on July 13 of that year he received perhaps the visit from her mother Catherine.
At the end of 1493, everything was ready for the fusion of the "Colossus". In the Old Court,
home for years workshop of Leonardo (on the site of the Royal Palace)
the clay model was ready and visible, but a sudden news stopped the availability of the metal:
the imminent invasion of Charles VIII of France, in Italy, for the war against the

 Aragonese Kingdom of Naples (1494),
made it urgent demand for bronze for the manufacture of weapons, defeating Leonardo's project,
which was deeply disappointed and saddened for the new economic problems caused
the failure commission.


       The Last Supper  

 In 1494 Leonardo, however, received a new commission,
linked to the convent of Santa Maria delle Grazie, a place dear to the Moor,
for the celebration of the Sforza family, which had just finished working Bramante.
Work proceeded with the decoration of the dining hall, a rectangular
where the Dominicans their meals.
It was decided to paint the walls with less traditional themes:
a Crucifixion, for which he was named Donato Montorfano who developed a traditional composition,
already completed in 1495, and entrusted to the

Last Supper Leonardo.
In this work, who raised him from the impending economic problems,

                                    Leonardo poured like a summa all studies
                       made by him in those years, representing a masterpiece.
The novelist Matteo Bandello, who knew Leonardo, wrote of him often

 seen "The morning to buon'hora to mount his su'l bridge, because the Cenacle is quite high off the ground;           
he used the rising sun not rising until all'imbrunita evening never the brush of his hand,
but scordatosi eating et drinking, without cease paint. He would then be dui,
three four days, that does not put v'averebbe hand, and yet lived talhora one or two hours a day

 and only contemplated, considered et essaminando to himself, his figures judged.

 I have also seen (According to the whim or caprice touching him) depart at noon, when the

Sun is in Leo, from the Old Court where that beautiful horse land composing, and venirsene

 straight to the Graces:
et ascended on the bridge pigliar the brush, et one or two strokes to give one of those figures

and immediately partirse et go elsewhere. "
Leonardo drew on the tradition of Florentine circles, but reinterpreting it in a very
original with a greater emphasis on the dramatic moment in which Christ says, "Some of you will betray me" and "movements of the soul" of the apostles upset. They are portrayed in

groups of three, as a series of successive waves of emotion, with a central and dominant isolated figure of Christ.
As we know Leonardo was not comfortable with the technique,
because the fast drying time of plaster required a decisive and quick, not compatible
with long studies, subsequent washes and his fine brushwork. Leonardo invented for this
a mixed technique of tempera and oil on two layers of plaster, which slowed down the execution phases work allowing them to make a greater harmony of colors and light effects and

 transparencies dear to him.
The work was completed in 1498, when it was mentioned in De divina proportione

 Luca Pacioli. The experiment, however, turned dramatically unsuited to a wet environment

such as the refectory, with the wall communicating with the kitchen: already in 1517

Antonio de Beatis wrote the first loss of color, at the time of Vasari were already evident, then were followed by restoration and repainting, as well as extremely dramatic events during the

Napoleonic occupation and the Second World War,
who had delivered a masterpiece extremely compromise, which has remedied, as far as possible,
the capillary restoration completed in 1999.

   The Danae and the work at the Castello Sforzesco   

On 31 January 1496, the successful staging of Paradise was replicated dall'allestimento
of Danae by Baldassare Taccone, performed in Milan in the house of the

Count of Caiazzo Francesco Sanseverino.
On the back of a Leonardo da Vinci folio, at the Metropolitan Museum,
is a preparatory study for the implantation stage:
the center of a niche was a character, perhaps Jupiter, flamboyant and an almond,
surrounded by a stage with curved wings, perhaps reserved to the musicians.
Other sources point out how the Olympians calassero top, remaining suspended in the air

between effects light to simulate a starry sky;
a system of winches and pulleys gave the actors the ability to move with ease.
At that time Leonardo worked together to decorate the dressing rooms in the

Castello Sforzesco, which stopped in 1496;
this year, by his note of the cost of a burial, he deduced his mother's death.
Work remains today only the decoration of the Hall Axis
plant with a dense network of high sensitivity nature, today appreciable only in general
by repainting necessitated several times to cover the gaps.
Of 2 October 1498 is the deed by which Ludovico il Moro gave him a vineyard in the

convent of Santa Maria delle Grazie and the monastery of San Vittore al Corpo.
Meanwhile, storm clouds were gathering on the horizon in Milan:
in March 1499 Leonardo would have gone to Genoa along with Ludovico, on which hung the
storm of war that he himself had helped to bring about;
while the Moor was in Innsbruck, trying in vain to ally the Emperor Maximilian,
October 6, 1499 Louis XII conquered Milan.
On December 14, Leonardo's 600 florins on the deposit
Hospital of Santa Maria Nuova in Florence and left Milan.

 The wandering period (1499-1508)   

The departure from Milan, occupied by the French, marked the beginning of a period of travel and wandering, that led him to visit shorter and cities, returning for a short time in Florence.

  A Mantova   

Fled to Mantua, host of Isabella d'Este, who had seen the Lady with an Ermine restandone affected.
It commissioned a portrait of Leonardo never completed, which keeps the preparatory cartoon,

now in the Louvre.
Despite the lure of Isabella, who wanted to make the court painter Leonardo replacing the old Mantegna, which did not appreciate the art of the portrait, Leonardo departed early, finding the environment Mantua perhaps too stuffy and altogether with limited income-generating opportunities for the continuing economic problems of the small duchy.

A Venezia    

This led him to Venice in March 1500.
The presence of the Florentine artist in Venice is evidenced by Luca Pacioli,

erhaps accompanied her in the city to prepare with the release of De divine proportion, which was illustrated with drawings perhaps derived from prototype Leonardo. Vasari did not mention the trip, perhaps because it is linked to the activities of engineer and mathematician rather than artistic disciplines. Here he was commissioned to design some defensive systems against the continuing

Turkish threat.
Leonardo devised a movable dam, to be placed on the Isonzo and on Vilpacco, able to cause flooding on principals land of the enemy. In any case also from Venice off again soon.
Perhaps in Venice did or still left some of his innovative studies on caricatures and grotesque

faces, whose influence law in some later works produced in Venice,
as The Old Giorgione or twelve Christ among the Doctors Dürer's stay in Venice.
Leonardo also had with him the cartoon for the Portrait of Isabella d'Este, who may have been
an example to push local artists in depth psychological portrait and greater
sensitivity to light effects.

Il ritorno a Firenze   

After visiting Rome and Tivoli in April 1501 he returned to Florence,
where not set foot in twenty years. Was welcomed at the canonical Amadori in Fiesole,
Albiera stepmother's brother, despite his father Piero was still alive;
probably the artist would have found uncomfortable in the house full of brothers who

did not even know and then turned out to be hostile to him after his father's death, about the inheritance.
During his absence, Florence had changed both politically and on the art scene.
Dead il Magnifico and chased his son Piero in 1494, had restored the full Republic,
headed by 1502 the standard-bearer for life Pier Soderini. New "stars" had risen to the fore,
including that of Michelangelo, more than twenty years younger than Leonardo,

with whom he never ran bad blood.
Leonardo was plagued by financial problems and in need of work.
So it was that the friend Filippino Lippi, who had previously received commissions

 left unfinished by Leonardo, relinquished the assignment in his favor of painting for the brothers Served an altarpiece for the high altar the Santissima Annunziata.
Leonardo, with Salai, then moved to the convent, but once again failed to complete the work

entrusted to him. The brothers had to settle for a cardboard with the Sant'Anna, then lost,
which enjoyed an extraordinary reputation among his contemporaries.
It remains a vivid description of Vasari
"Finally made a cardboard dentrovi a Madonna and a S. Anna, with Christ,
which also did not marvel all craftsmen, but she was finished,
in the room lasted two days to go and see her gl'uomini and women, young et old,
as you go to a solemn festival, to see the wonders of Leonardo, who made surprise all the people. '
(Giorgio Vasari, Lives of 'Most Excellent Painters, Sculptors, and Architects (1568),

The Life of Leonardo da Vinci.)
It now seems certain that the work is not the carton of St Anne in London today,
it is instead a work painted by Louis XII perhaps a little later, by 1505,
and from the Milanese house of accounts Arconati;
rather paperboard Florentine had to derive the Saint Anne, the Virgin and Child with lamb Louvre
completed, however, many years later.


    La Madonna dei Fusi   

Isabella d'Este in the meantime trying to get the services of Leonardo for his study
and a portrait, according to his plan to compete in the major painters of the period,
which was to involve also Giovanni Bellini, Giorgione and others.

Through the intercession of the Carmelite Pietro da Novellara asked the portrait

and in the alternative, "A small painting of the Madonna and sweet como devotee

 is its  natural," but the monk replied that
"They have his isperimenti mathematical distracted so much from

the paint that can not suffer the brush."                      
In the letter dated April 14, 1501 the brother informed her that Leonardo was performing a "shirker"
to the secretary of the king of France Florimond Robertret,

which depicted the Virgin in the act of "inaspare the time"                  
and Child while grabbing the reel as if it were a cross.
This is certainly the Madonna dei Fusi, of which there are many versions, no fully autograph.
The closest to the hand of Leonardo is believed that the collection of
Duke of Buccleuch in Drumlaring at Edinburgh Castle, perhaps the oldest,
and one in a private collection in New York.
The letters testify to that Leonardo was now in Florence, fully occupied as a painter.


The service of Cesare Borgia  

In 1502, Leonardo was hired by Cesare Borgia as a military architect and engineer.
The two have already got to know each other in Milan in 1499.
The son of Pope Alexander VI, called "Duke of Valentino," was one of the most brutal tyrants

of the moment and took Leonardo, who had arrived in Cesena, in various tasks related to the continuous military campaigns, how to detect and update the fortifications of the city of Romagna conquered.
For him, he developed a new type of gunpowder, consisting of a mixture of sulfur, charcoal 

and saltpeter, studied flying machines and tools for submarine warfare.
In August, spent some time in Italy, from where he set off to inspect the fortresses

of Lombardy Borgia;
also drew detailed maps for easy moves military-strategic forces.
In the wake of Valentino attended one of the most bloody and cruel campaigns of the time,
the sneak attack against Urbino. Just in Urbino Leonardo shook friendly relations

 with Niccolò Machiavelli, probably already known in Florence.

    Study of the the Battle of Anghiari    

Since March 1503 he was again in Florence, surviving almost to the collapse of the domains of Borgia.
In April Pier Soderini entrusted the task of decorating one of the great walls

of the new Salone in Palazzo Vecchio, great work in size and ambition, which would
expected in the following months.

In July, meanwhile, the Republic gave him a complex hydraulic project-military
for the dam Arno so as to head off rebel against Pisa:
Leonardo went to the city besieged by the Florentines, together

with Jerome Alexander and Filicaja Albizi, but his project failed due to a

calculation error, which he sent on a rampage Gonfaloniere Soderini.
Back in town, then took up the project in the Palazzo Vecchio.
In the Salone had to be shown some military victories of the Florentines,
celebrating the concept of libertas Republican foes and tyrants.
A Leonardo was given an episode of the clashes between the army of Florence and

Milan, 29 June 1440, the Battle of Anghiari, while on the opposite wall would have to work Michelangelo Buonarroti, the Battle of Cascina (July 29, 1364, against the Pisans).
For different reasons neither of these murals was completed, nor have they kept the original cartons,
although there remain some studies autographs and copies of other ancient authors.
Leonardo studied in particular a new technique that quickly raised by the fresco,
recovering from the Historia naturalis of Pliny the Elder encaustic.
As for the Last Supper This choice turned out to be unsuitable dramatically when it was too late.
The vastness of the painting did not allow it to reach fires with a temperature sufficient to dry the colors,
that flowed on the plaster, or tending to fade, if not disappear altogether.
In December 1503 the artist interrupted so the transfer of the painting from the wall cardboard,
frustrated by a new failure.
Among the best copies taken from Leonardo's cartoon is that of Rubens, now in the Louvre.
Also lost the cardboard, the last traces of the work were probably
covered in 1557 by the frescoes of Vasari.

       La Gioconda   
    In this time he began the masterpiece that made ​​him famous throughout the centuries,

 the Mona Lisa.
Traditionally identified as Lisa Gherardini,
born in 1479 and wife of Francesco Bartolomeo del Giocondo

(hence the name "Mona Lisa"), the painting is considered the most famous

 portrait in the world, goes far beyond the traditional boundaries of portraiture.

As he wrote Charles de Tolnay (1951)
"The Mona Lisa, the individual - a sort of miraculous creation of nature -

is at the same time the species:
the portrait exceeded the limits social acquires a universal value.
Leonardo worked on this both as a researcher and thinker, both as a painter and poet;
and yet the philosophical-scientific side remained unanswered. But the formal aspect -

the new layout, the nobility and dignity of the attitude of the resulting model - took action
termination on the portrait in Florence the next two decades [...]
Leonardo created the Mona Lisa with a new formula, more monumental and at the same

time more lively, more concrete, and yet more poetic than that of its predecessors. Before him,

 in the mystery of the missing portraits;
artists have shown that external forms without the soul or, when they characterized the soul itself,
it sought to reach the audience through gestures, symbolic objects written.
Only in Gioconda exudes a riddle:
the soul is present but inaccessible. "

The death of his father and the Treaty models birds    

On 9 July 1504 his father died Piero, Leonardo wrote several times to the fact,

 in apparent agitation:
«Wednesday at 7 o'clock died Ser Piero da Vinci, on the day July 9, 1504,

 Wednesday at 7 am near," and yet, 'Addi July 9, 1504 in Wednesday at 7 o'clock died

Piero da Vinci, notary at the palace of the Podesta, my father, at 7 o'clock.
Years old was 80. He left 10 children boys and two girls. "The father did not do it and heir,
against the brethren who opposed the illegitimacy of his birth,
Leonardo asked in vain for recognition of its reasons: because after the court which he

 promoted, only April 30, 1506 there was the liquidation of the estate, from which Leonardo

 was excluded.
In the early 1500 Leonardo deli pays particular attention to the study of the flight and the

 project a new flying machine. Realizing the business of human flight is
the challenge amiziosa and Leonardo pursues the idea of writing a treatise on the flight

 divided into four chapters.
At foglio3r Manuscript K Leonardo notes:
Divide the Treaty of birds in four books, of 'which is the first to fly the beat of Alie:
the second beat of the flight without wings, for the favor of the wind, the third of the fly in

common, such as birds, bats, fish, animals, insects, and the last movement of the instrument.
Leonardo did not ever complete the drafting of the Treaty on the flight but in 1505 please fill

in the Codex on the Flight of Birds, now housed in the Royal Library of Turin.
The Code of the flight is the collection of more mature thought of Leonardo inherent in the

study of the flight, and in the pages of this precious manuscript that Leonardo designed his most advanced flying machine:

The great Nibbio 

 The Great Nibbio, The Leonardo's flying machine in the Codex of Flight
In the three years following
Leonardo developed further his studies on the anatomy of the             

 birds and the air resistance and around 1515, on the fall of the weights 

 and  the motions of the air.
From this knowledge then tried to build original flying machines,

in some cases put in place, as seems to confirm a note autograph

unspecified   date:
"Piglierà the first flight of the great bird on the back of his magnum Cecero filling the universe with awe, filling with its fame all writings and eternal glory to                                     

the place where he was born. "
It is believed that Leonardo did experience the flight attendant to one of his trusted
Tommaso Masini said "Zoroaster" from the hill of Fiesole, but did not get a success:
it seems that the victim fell into ruin even breaking a leg.


Leonardo and Michelangelo    

The relationship between the two geniuses of the Renaissance, Leonardo and Michelangelo,
was difficult, often tense, due to the generational difference

 (Michelangelo was 23 years younger than Leonardo)
of different characters and artistic ideals irreconcilably far:
The first was thoughtful, versatile and interested in the natural world and the second most

impulsive, notoriously unruly and idealistic.
There is no direct evidence of their enmity, but several clues and indirect evidence.
In the Treatise on Painting, for example, Leonardo condemned the "excesses anatomical and muscular rhetoric" that are part of the style of Michelangelo and his followers, without ever directly mentioning the rival.
The Anonymous Gaddiano remembers them in a novel, in which the two artists,

in Piazza Santa Trinita, met and Michelangelo, contemptuous and argumentative,

 Leonardo pressed about the  interpretation of a verse of Dante, under discussion.
Leonardo's reticence to accept the provocation generated the wrath of Michelangelo,
that the derision about the failed project of the bronze horse ending:
"Et t'era who believed that from this 'caponi de' Milanesi?"
Misunderstandings and rivalry had come on even during double official commission in

Palazzo Vecchio, but, perhaps because of the lack of realization of the project,

the sources are silent about it.
Before leaving Florence there was another episode that affected the two:
Michelangelo had in fact completed his David and the Florentine artists were called in committee
to decide on the location of the statue in Piazza della Signoria, January 25, 1504.
Of Botticelli, Andrea della Robbia, the Chronicle, Filippino Lippi, Perugino, Lorenzo di Credi,
Giuliano and Antonio da Sangallo, Leonardo took the podium to advise,
following an idea of ​​Giuliano, a secluded location for the statue in the Loggia della Signoria,
close to the wall maybe short framed by a niche "so that no faults ceremonies delli official".
Its position, which obviously provoked the opposition of Buonarroti, had a follow-minority
Finally, the prevailing hypothesis of Filippino Lippi, to a position of maximum exposure outdoors
dominant and authoritative in front of Palazzo Vecchio, the most important building in the city,
as well as the nerve center of political and social life in Florence.

The second stay in Milano   

In Florence, Leonardo began to be flattered by the French governor of Milan,

 Charles d'Amboise, urged that, since 1506, to enter the service of Louis XII.
The following year saw the king himself to ask specifically Leonardo, who finally agreed

 to return to Milan in July 1508.
The second stay in Milan, which lasted until 1513, with some travel from October 1506 to January 1507 and from September 1507 to September 1508, was a very intense period.
He painted the Saint Anne, the Virgin and Child with lamb, completed in collaboration with the

 De Predis, the second version of the Virgin of the Rocks and took care of geological problems,

and urban basins.
Studied among other things a project for an equestrian statue in honor of Gian Giacomo Trivulzio,
the creator of the French conquest of the city.
He lived near San Babila and its financial status is the record of a commission obtained
for almost a year of 390 and 200 francs money from the king of France.
On 28 April 1509 he wrote that he solved the problem of squaring curvilinear angle

and the following year went to study anatomy with Marcantonio della Torre, a young professor

at the University of Pavia, for this purpose wrote, to give "the real story of the human figure,

which it is impossible that the ancient and modern writers I could never give real news,

without an immense and tedious and confusing writing and length of time;
but for this very short way figurarla "- which is representing directly with drawings,
"It will give full and true information. And so that this benefit I give unto men should

not perish, I teach how to reprint it in order ".
During his short trips visited Como, then ventured towards the slopes of Monte Rosa,
(At that time it was impossible to climb up to the summit which is 4,634 meters high well)
then with Salai and the mathematician Luca Pacioli lived in Vaprio d'Adda, near Bergamo,
where he was given by his father the young Francesco Melzi, the last and dearest of his

students who followed him until his death.
In 1511 the death of his supporter, Charles d'Amboise.
Two years later the new War of the League of Cambrai drove the French from Milan,

who returned to the Sforza.

   A Roma    

Uncertainty of the situation 24 September 1514 Leonardo went to Rome, bringing students

 closer together, Melzi and Salai. Here Giuliano de 'Medici, brother of Pope Leo X grants him his favor, obtaining for him an accommodation in the apartments of the Belvedere in the Vatican.

 Here the artist devoted himself to his scientific studies, mechanics, optics and geometry and

 tried on fossil near Monte Mario, but complained Giuliano that he should be prevented from his studies of anatomy in the Hospital of the Holy Spirit. There was no public commissions,
but he had the opportunity to review Bramante and Giuliano di Sangallo, who were occupying

 the building of St Peter, Raphael, who frescoed the papal apartments, and perhaps even Michelangelo, from whom he shared the ancient enmity.
He was involved in the draining of the Pontine marshes, whose work had been

contracted by Giuliano de 'Medici -
The project was approved by Pope Leo X December 14, 1514, but was not executed for

the death Giuliano is that of the pope in a few years - and of the port of Civitavecchia.
With Giuliano and the pope made ​​a trip to Bologna,
where he met directly Francis I of France.


  Leda e il cigno,   

According to Vasari, this during his short stay in Rome,
made 'for Messer Baldassarre Turini da Pescia, who was date of Leo,
a picture of a Madonna with child in arm with infinite diligence and art »
and drew "a little boy who is beautiful and graceful to a marvel, which are both in Pescia" but of the two works is lost every trace, together with Leda and the Swan, known at the time, and still seen by Cassiano dal Pozzo in 1623 in Fontainebleau:

"Leda standing, almost all naked, with the swan and two eggs at the foot of the figure."
In Rome also began to work on an old project, that of burning mirrors that would be

 used to convey the sun's rays to heat a tank of water, helping to drive the machines.
However, the project encountered a number of difficulties mainly because

 Leonardo did not get along with its German workers, specialists in mirrors, which were made on purpose to arrive from Germany.
At the same time were resumed his studies of anatomy, has already begun in

Florence and Milan, but this time things got complicated
an anonymous letter, sent probably in revenge by two workers Germans accused of witchcraft. In the absence of protection of Giuliano de 'Medici, and faced with a situation which heavy Leonardo was forced, once again, to leave.
This time he had decided to leave Italy.
He was old, needed peace and someone to appreciate and help.
The last news of his Roman period date to August 1516,
when measuring the size of the Basilica of St. Paul Outside the Walls,


    In France, in the service of Francis I      

In 1517 Leonardo left for France, where he arrived in May, together with Francesco Melzi
and the servant Battista de Vilanis, being housed by the king in the castle of Clos-Lucé,
near Amboise, and honored with the title of premier painter, architect, mecanicien et du roi,
with a pension of 5000 crowns.
Francis I was a sovereign cultured and refined, especially Italian art lover,
as demonstrated in the following years with honors welcoming other artists

(Primaticcio Rosso Fiorentino, Andrea del Sarto, Benvenuto Cellini).
The last three years in France were definitely the quietest time of his life,
assisted by two loyal students and though weakened by old age and a probable cerebral

thrombosis that paralyzed his right hand, he was able to continue with passion and dedication

to their studies and scientific research.
The high regard in which he enjoyed is also demonstrated by the visit received, October 10,
Cardinal of Aragon and its aftermath: Leonardo showed him "three square
one particular woman Fiorentina done from life to istantia of the late mag.co Juliano de Medici,
the other Joane de San Bap.ta young age one of the Madona et son that the standard seats

in the lap of Santa Anna tucti perfectissimi, et's true that he came to esserli certain paralesi it the Dextra, it can not be bona expectare more thing. Has created a well-facto Milanese who works

very well, although M. et p.to Lunardo can not Colorir with that dulceza that solea,
while serves to make drawings et teach other.
This gentilhomo composed of anatomy so particularmente with demonstratione de la pictura
So from members as of muscles, nerves, veins, joints, intestines of a lot of bodies

of homini that de done, has never been so de facto anchora by another person [...]

He also composed the nature of the waters, of several machines and other things, according to reported him countless volumes et tucti language vulgare,
if they come to light which will be very profitable et dilectevoli. "
Designed the Royal Palace in Romorantin, Francis I wanted to build for his mother Louise of Savoy.
This was the project of a small town, for which foresaw the movement of a river of water that enrich
fertilizzasse and the nearby countryside, "El river half does not receive turbid water,
but this water goes to them were of holes in the ground, with four molina entry and four exit [...]
the river has led to Romolontino Villafranca, and the like is made of its people [...]
if the river mn [Bonne Heure], a branch of the river was [Loire] is sent into the river Romolontino,
with his murky waters it Grassera campaigns over which it adacquerà, and make the land fertile. "
Participated in the celebrations for the baptism of the Dauphin and those for the wedding of

Lorenzo de 'Medici.
Among his works as a curator of festivals and equipment is reminiscent staged in Lyon

in 1515 and Argenton in 1517, in both cases, to celebrate the presence of Francis I.
It was the automaton of the lion, who was able to walk and then stop opening the chest
"All filled with lilies and other flowers, [...] who was a marvel to the king."
The last date found on a manuscript of Leonardo dates back to June 1518:
taken from calculations of geometry, studies are abruptly interrupted with a "etc.,

 because the soup is cold!"
This is a rare record of instinctive life, which makes the human dimension of the character,
pressed by the calls of someone, to break the concentration to eat.

      The death     

The tomb of Leonardo, Château d'Amboise
On 23 April 1519 he drafted a will before a notary William Boreau the presence of five witnesses
Francesco Melzi, and inseparable:
dispose of wanting to be buried in the church of Saint Florentin, with a funeral accompanied by
chaplains and by the Friars Minor, as well as sixty poor people, each regent a torch;
called for the celebration of three solemn masses, with deacon and sub-deacon,

 and thirty harvest "low", St. Gregory, Saint-Denis and in the Franciscan church.
A Francesco Melzi, executor, let "them books [...] and other INSTRUMENTI et
Portracti about his art et de Pictori industry, "as well as the collection of drawings and wardrobe;
the servant De Vilanis and Salai half for each "one Iardino that drilling of the walls of Milan [...]
in which the aforesaid Iardino Salay has built et constructa a house ";
the maid Maturina of cloth and two ducats to his brothers Florentine heritage in the Tuscan city,
ie 400 shields deposited in Santa Maria Nuova and a farm in Fiesole.
Leonardo died shortly thereafter, on May 2. Francis I, Saint-Germain-en-Laye where he was, he learned of the death directly from Melzi and let go of a weeping disconsolately.
On August 12, a record recalls how "he was buried in the cloister of the church
[Saint-Florentin in Amboise] M. Lionard de Vincy, Milanese nobleman and Premier Painter and Engineer and Architect of the King, meschanischien of State and
former director of the painting of the Duke of Milan. "
Fifty years later, violated the grave, his remains went missing in the unrest of the religious struggles
between Catholics and Huguenots.
Thirty years earlier he had written the words that sound prophetic in his case:
"Yes, as a day well spent gives happy sleep, so life well used gives die happy. '
Copies of Leonardo's writings on painting were already circulating in the sixteenth century:
Vasari reported by an anonymous artist from Milan, who showed him "some of the writings of Leonardo, while characters written with the left hand on the reverse side, which treat of painting

and de 'ways of drawing and coloring ";
Benvenuto Cellini had written of Leonardo's perspective.
Thanks to the efforts of Cassiano dal Pozzo, a collection of manuscripts of Leonardo,
drafting extremely short of that put together the pupil and heir, Francesco Melzi,
was published for the first time in Paris in 1651, together with the French translation,
with engravings taken from drawings by Nicolas Poussin;
another Italian edition of the Treatise on Painting, was published in Naples in 1733.
The painting, Leonardo, science, representing "the way with more truth and certainty the works of nature," while "the letters represent more truly the words to meaning."
But, he adds Leonardo shooting a Aristotelian concept,
is "the most wonderful science that represents the works of nature,
that what is [...] the works of men, as poetry, and the like, passing through the human language. "
Leonardo also studied first in Europe the ability to project images from life on a sheet where

they could be easily copied, with the so-called camera obscura Leonardian.
He also was among the pioneers of the use of oil painting in Italy, he used mainly in mixed media, mainly for touch-ups.
"I know that, not me letters, he judges that some presumptuous I could reasonably blame
coll'allegare I be man without letters. Foolish people!
Such people do not know that I could, even as Mario replied against 'Roman patricians,

I do answer, saying:
"Those who dall'altrui labors if they adorned themselves, my I do not want to grant the same."
Or they do not know that my things are more to be learned from experience, that the word of others,
which was teacher who wrote well, and so the teacher for an air and that in all cases will attach »
(Codex Atlanticus to 119 v)
"Omo without letters" stands for man who does not know the Latin
but he does not need the knowledge of the Latin for "I have so many words in my mother tongue,
ch'i 'm'ho rather by doler good understanding things, that the lack of words,
with which well express my concept of the mind ";
and when the vulgar has full ability to express any concept,
the problem remains the truth of what is argued.
The Vitruvian Man, a study of proportionality of the human body, Venice,
AccademiaSecondo the thought of Leonardo,
a first truth we can draw from the direct experience of nature, from the observation of phenomena:
"Much greater and more worthy thing to read" is not attach the authority of authors of books, but
attach the experience, which is the master of those authors. Those who argue citing the authority
other writers are swollen "and pompous,
clothes and ornaments, not of themselves, but of others' labors, and my not grant the same to me;
and if I despise inventor, how much more them, not inventors,
but trumpeters and reciters of the works of others, will be blamed. "
And if they criticize him, saying that "my evidence against all'alturità be of some days
men of great reverence hereafter to 'their inexperienced iudizi "
it is because they do not consider that "my things to be born under the simple and pure

 experience, which is true teacher. "
"I believe that instead of defining what is the soul, which is something that you can not see,
much better is to study those things that you can learn with experience,
because not only the experience gap.
And if you can not apply one of the mathematical sciences, we can not be sure. '
If the experience is to know the reality of things, but still does not give the rational necessity of phenomena, the law that is hidden in the manifestations of things: "Nature is forced by reason

of his law, that she infusamene lives "and" no effect in nature without reason;
you mean the reason and you do not need experience, "
in the sense that once it is within the law governing this phenomenon,
no need to repeat the observation, the intimate truth of the phenomenon is reached.
The laws that govern nature are expressed through mathematics:
"Nissuna human investigation can be questioning will true science, s'essa does not pass through
the mathematical demonstrations,"
standing still the principle that "if you say that the sciences, which Principiano and end up in the mind,
have truth, this is not allowed, but denies, for many reasons, and the first,
that does not happen in such discourses mental experience, without which nothing gives self-confidence. "
The rejection of metaphysics could not be expressed more clearly.
Even his conception of the nature of his research follows the approach:
"In its [nature] inventions nothing is lacking and nothing is superfluous and wrong

with counterweights, when it makes them members of the motion acts panels bodies animal

 models, but puts it into the soul of the container body,
that is the soul of the mother, who first made the figure of the man in the matrix and in due time awakens the soul inhabitant of that which ought to be, what the first was still asleep and protect

the soul of the mother, what the nurses and quickens the umbilical vein, "and adds that with

prudent irony "Definition as given the rest of the soul will leave the minds of 'brothers, fathers of' peoples, which inspired them to know all the secrets.
I leave the letters crowned star [the Scriptures] because they are supreme truth. "
But insists: "And if we doubt the certainty of each thing on the senses,
how much more are we to doubt the things they rebel senses,
as the essence of God and the soul and the like, which always takes place and contend.
It really happens where there is no reason that always make up for the cries,
which does not happen in certain things. "
Recognizes validity to the study of alchemy, "partoritrice of the simple and natural"
not already considered a magical art but "ministratrice de 'simple products of nature,
which office the fact that it can not be kind, because she is not organic instruments,
hills which it can deliver that instruction that uses homo by his hands, "that science by which man,
starting from the simple elements of nature, it produces compounds as a modern chemist;
However, the alchemist can not create any simple element, as evidenced by the ancient

 alchemists, than ever "s'abbatero to create the least thing that you can from it! create nature"
and would have been worthy of the highest praise if "fussino were not the inventors of harmful

things, as veneni and similar ruins of life and mind. "
Instead harshly censor of magic, "necromancy, ovver flag flying banner blowing in the wind,
guidatrice the foolish multitude. " The necromancers' have empiuti books,
stating that the charms and spirits endeavor and without language they speak, and without

organic instruments, without which you do not speak little, speak and bear serious weights,

 face and inundating rain and that men will be converted in cats, wolves and beasts,

 although the first beast when accessing those who say such a thing. "
Leonardo is best known for his paintings, for his studies on the flight,
probably much less for the many other things that it was instead a true precursor,
such as in the field of geology. He was among the first, in fact, to understand what they were fossils,
and because they were marine fossils in the mountains. Contrary to what was believed at that time,
namely that it was the evidence of the great flood, the biblical event which would have drowned

the whole earth, Leonardo imagined the movement of water masses on earth, like the blood circulation, with a slow but continuous change, coming to the conclusion that the places where the fossils surfaced, time must have been the seabed.
Although with very original reasoning, the conclusion of Leonardo was surprisingly accurate.
Leonardo's contribution to almost all scientific disciplines was decisive:
in astronomy had insights, as the heat of the sun, the twinkling of the stars,
on Earth, the Moon, the centrality of the Sun,
still for so many years would raise contrast and opposition.
But in his writings are also examples that show its ability to make
so dazzling of difficult concepts;
at that time was far from having formulated the laws of gravity, but Leonardo already compared
the planets magnets that attract each other, thus explaining very well the concept
of gravitational attraction.
In another of his writings, more on this topic, resorted to an image very suggestive;
Leonardo said: imagine to make a hole in the ground, a hole that passes through from side

 to side  through the center, a kind of "bottomless pit" if you throw a stone into the well,
the stone oltrepasserebbe the center of the earth, continued on its road going up the other side,

 and then would come back after again above the center,
dates back over here. This back and forth would last for many years,
before the stone is still definitely in the center of the Earth.
If this space was empty, that is totally devoid of air, it would, in theory, a possible
apparent, the model of perpetual motion, the possibility of which, moreover, Leonardo denies
writing that "nothing will move itself is insensitive, so, moving, fia disequale moved by weight;
ceased and the desire of the first motor, the second will cease immediately. "
Even in botany Leonardo made important observations:
first noticed that the leaves are arranged on the branches not randomly but according to

mathematical laws (Made only three centuries later) is a growth in fact, that the leaves,
that avoids the overlap to take advantage of the greater amount of light.
He found that the concentric rings in the trunks indicate the age of the plant,
an observation confirmed by Marcello Malpighi more than a century later.
He also noted the eccentricity in the diameter of the logs, due to the greater growth of the

shaded part.
Especially first discovered the phenomenon of the rise of water from the roots to the trunks by capillarity, anticipating the concept of sap ascending and descending.
To all this was added an experiment that anticipated many centuries hydroponics: having studied hydraulics, Leonardo knew that it was necessary to raise the water
perform work; then in plants, in which the water rises through the roots, a kind of work had to be done.
To understand the phenomenon took off the ground, placing the plant directly into the water,
and observed that the plant could still grow, albeit more slowly.
You can take a final judgment on the position that it is up to Leonardo in the history of science
quote Sebastiano Timpanaro: [80] "Leonardo da Vinci draws from the Greeks, the Arabs,

by Jordanus, by Biagio da Parma, by Albert of Saxony, John Buridan, doctors of Oxford,

the precursor of the unknown Duhem, but draws on ideas more or less questionable.
You and your new curiosity for every natural phenomenon and the ability to see to the

naked eye that which barely be seen with the aid of tools.
Because of his unique and powerful sense of observation, he differs from his predecessors

and Galileo.
His writings are essentially ordered and trying to translate them into treaties of the purest modern science, you pervert. Leonardo (you have to say it out loud) is not a super-Galileo is a great curious nature, not a scientist-philosopher. It may be that sometimes go even further than Galileo,
but there is another spirit.
Where Galileo would write a treatise, Leonardo writes one hundred or one hundred aphorisms notations from the truth; while Galileo is so consistent as to become in a few moments conseguenziario. Leonardo looks and note without worrying too much about theories.
Many times records the fact without even groped to explain it. "

            The inventor of the flying machine project        

On 25 November 1796 the manuscripts of Leonardo withdrawn from the Biblioteca Ambrosiana arrived in Paris and from their analysis, the Italian physicist Giovanni Battista Venturi,

 then in France, drew a Essai sur les ouvrages physico-mathématiques de Leonard de Vinci,
excluded from this study da Vinci on the flight, judging probably just a quirk chimerical.
In 1486 Leonardo expressed his faith in the possibility of human flight:
"You know the man with his own-designed and large wings, pushing down against the air

 resistance, winning, being able to subdue and rise above it. " From March 14 to April 15, 1505

wrote of what was to be an organic models Treaty birds, from which he wanted to extract the

secret of flight, extending his studies in 1508 to the anatomy of birds and air resistance and,

around 1515, adds the study of falling bodies and the movements of the air.
Call motorcycle instrumental human flight achieved with the use of a machine:
locates in the most simple parachute flight:
"If a man has a nappy clogged pavilion, which is 12 for face and upper arms 12,
will throw herself of any great height without injury to himself. "
By analogy with the weight and the wingspan of the bird tries to establish the wingspan that
the machine should have and what force should be used to move and sustain it.
Leonardo's faith in human flight appears to have remained unchanged throughout his life,
despite failures and the difficulty of the enterprise:
"Piglierà the first flight of the great bird on the back of his magnum Cecero (Mount Ceceri,
near Florence), filling the universe with awe, filling his fame all the scriptures and
Eternal glory to the place where he was born. "
An experiment in this direction took place and really made a guinea pig his friend

Tommaso Masini.
During his lifetime, Leonardo invented many concepts, some of them, like the flying machine,
were real prototypes. Her notes contain several inventions in the military:
scorpions, a machine "that little 'draw stones, darts, sagitte»
which can also destroy the enemy machines;
the cortaldi, guns to use against ships; coils, suitable against the "galleys,
to offend the enemy from afar. Vole throw herself 4 pounds of lead ";
the zepate, rafts to burn enemy ships at ports
and designing ships with spikes that break the enemy hulls and incendiary bombs made

of coal, saltpeter, sulfur, tar, incense and camphor, a fire "is so eager to brusare,
that followed the timber right under the water. "
Another project would include the diver - there are those who thought even to the sub -
about which he wrote but did not want to disclose "to the evil nature of men,
them which userebbono them assassinementi ne 'funds seas with Navili break down and engulf
men with necks that are inside. " Do you think the current bike, chopper,
a model which has been realized in the park of the castle of Clos-Lucé,
a device for gearing that has been interpreted as the first mechanical calculator,
in a car driven by a spring mechanism and an automatic loom,
reconstructed from the National Museum of Science and Technology in Milan,
weaving cloth 2 inches per minute, designed the purple organist.
During his years in the Vatican invented an industrial use of solar energy,
through the use of concave mirrors to heat water.

      Studies in Anatomy  


Female anatomy, Windsor, RealiGli collected writings of anatomy prior to the work of Leonardo,
such as those of Mondino de 'Luzzi or Guy de Chauliac, resuscitating the tradition of Galen
and were therefore devoid of any experimental verification.
The insatiable desire to know, to understand everything he saw, brought Leonardo to explore everything.
Even the human body fascinated her as a perfect machine and much more complicated

machines made ​​of gears.
Leonardo wanted to know what was in it, how it works and what happens when it finally

stops with death.
For this, first to Milan at the end of the fifteenth century, and then in Florence in the early

 sixteenth century, used to go in secret morgues and using scissors and scalpel dissected corpses;
at least thirty, according to the report of his contemporaries.
In his drawings also show the instruments then in use by surgeons, saws and retractors.
The anatomy was in its infancy, the ideas on the human body were very confused.
He can rightly be considered the founder of the science,
together with at least the Belgian Andreas Vesalius (1514-1564),
De humani corporis whose work factory was to appear in 1543.

It is known the fact of a Florentine of his experiences: "this old man, a few hours before his death,
he told me he was over a hundred years, and he did not feel any lack of it the person, other than weakness; and so standosi to sit on top of a bed in the Hospital of Santa Maria Nuova in Florence
without other movement or result of distress, passed from this life. And I did anatomy,
to see the cause of such a gentle death. "

Leonardo studied anatomy in three distinct periods: in Milan, between 1480 and 1490, worked

on it, giving particular attention of the muscles and bones, as a function of his artistic activity;
subsequently in Florence, between 1502 and 1507, is applied in particular of body mechanics,

 and finally, 1508 to 1513, in Milan and Rome, became interested in the study of the internal

organs and blood circulation.
Movement of braccioLeonardo was the first to represent the interior of the human body with a

series of drawings;
it was also a whole new way to "look inside" the body, among other things, breaking old taboos.
There are hundreds of drawings now preserved at Windsor Castle, and owned by the

Queen of England, that display what was only described in words and fuzzy. Leonardo wrote:
"By what letters descriverai this heart, that you are not a wicked book, and how much longer

 write to the minute, the more you will confuse the mind of the listener, and always will need to

sponitori or return to Scanno, in you which is very short and gives news of a few things

compared to all of the subbietto you want INTEGRAR news. "

Leonardo invented the anatomical illustration.
He also invented a way to illustrate that is still used by modern designers,
the so-called "image exploded" an example is looking like Leonardo was a head section,
drawing the skull and the brain in sequence so as to show how they enter the one inside the other.
He studied the bones, muscles, arteries, veins, capillaries, failed to understand the age-related changes and even to realize arteriosclerosis. Escaped him instead the role of the heart,

studied in Rome until 1513:
"All the veins and arteries arise from the core, and the reason is that the

increased thickness that is in these veins arteries and is in conjunction with the core that they

have, and how much more if removano from the core, the more you thin and divide in the

most minute ramifications, "and this belief derives from the analogy with plants,

which have their roots in the lower part enlarged, "it is clear that the whole plant originates

such as thickness, and consequently the veins originate from the core,

where is their greater thickness "

Similarly his studies of the botanical astray, making him believe that the circulation worked
as the sap of plants, with an ascending and a descending sap.
But the heart had identified the nature of muscle:
"The core is a major muscle strength, and powerful muscles above the others"
but also as an equivalent of a stove to give heat to the body: "The heat is generated by the

 motion of the core; and this occurs because, when the heart faster you move, the more

heat multiply, as taught by the wrist de 'feverish, driven by the beating of the heart "
Among his anatomical drawings, the most spectacular and impressive are those that show

a fetus before birth:
images were completely new for its time, and certainly shocking
Leonardo also studied the mechanisms of the eye to understand how the

 three-dimensional view, due to the superimposition of two images which are slightly staggered.

Boiled a bull's-eye in a egg white, so that it can dissect and see what is inside.
He found the retina and the optic nerve, and reported these observations in his drawings.


Hydraulic Works 

The hydraulic studies water ca 1508 In the seventeenth century, Francis Arconati
son of Count Galeazzo da Vinci drew from the writings of these donated to the

Biblioteca Ambrosiana, a treaty which he called Del bike and measure the water, which,

however, will be published only in 1826.
Leonardo devoted himself to hydraulic studies from his stay in Milan, already full of canals,

and Lombardy, crossed by an extensive network of canals.
Collaborated with the Republic of Venice for the arrangement attitude of the river Brenta,
to prevent flooding and make it navigable, but do not know works on its projects,
some of which, particularly grandiose, are attested by his writings: a channel that combines

Florence to the sea, obtained by adjusting the course of the Arno, the draining of the Pontine Marshes, Lazio, which should have been made by diverting the river Ufente;
channeling the French region of Sologne, with the deviation of the Cher River, near Tours.
Leonardo also designed machines for the use of water power for the drying and the raising

of the water.
According to his custom, he studies the nature of water:
"The four elements below the second men grieve and second volatility.
This has never rest insino which is connected to its maritime element where
they are not harassed by the wind, is established and rests with its superfizie equidistant

from the center of the world " its origin, movement, certain features, such as foam:
"The water that falls from the top in the other water, encloses inside itself certain quantity of air,
which by the floods hit with it and with fast motion Kazing up reaching to the left superfizie

dressed in thin body moisture sperico, circularmente departing from the first percussion ».
Watch the visual effects on the water surface and finds that
"The image of the sun dimostrerrà more polished nell'onde minute that the big waves»
and that "the rocket of the sun, for the past rattles them [the bubbles] superfizie of water,
sends it to the bottom of water a simulacrum of it rattle in the shape of a cross.
I have not yet investigated the cause, but I estimate for the cause of other small rattlesnake

sien joint it rattle around more. "
Takes care of the fossils found in the mountains and joked with those who believe in the Flood:
"The foolishness and simplicity of those who want the animals in this Fussin lochi distant

 seas carried by the flood.
As another sect of ignorant state the nature or conceal them in such lochi created

for infrussi celestial [...] and if you tell them nichi [shells] that for them outside of Italy away

from them seas, in such a height is vegghino alli our times, it was because of the flood that

 left them there, I will say that believing that this flood superassi the highest mountain of

seven cubits - as those who wrote 'the measured! -
such nichi, which are always close to 'quarrels of the sea,
were to stand over these mountains, and not so little above the root of 'mountains.'
He is convinced that with time the earth will end up being completely submerged in water:
"Perpetual them are low lochi the bottom of the sea, and the other hand there are the tops of 'mountains;
idea keep the earth will sperica and all covered from the waters, and will inhabitabile. "

      Civil engineering and architecture of Leonardo    

Project centrally planned church, Paris, Institut de France
Vasari writes that Leonardo "architecture still fe 'many designs such as plants of other edifices
and was the first still that boy, discorresse over the river Arno to put it into channel from Pisa to Florence " evidence that, apart from that on the occasion of the project for deviating the Arno,

 which occurred in 1503, Leonardo was not "young man", shows that the interests of Leonardo

or requests addressed to him concerned especially projects of hydraulic engineering or military.
On the other hand, note letter to Ludovico il Moro in 1492, Leonardo has his powers of a military nature, but adds that in time of peace thinks "Perfect satisfaction compared to any other in de architectura, in the composition of public and private buildings,
et in guiding water from one place to another. "

In Milan will in fact only the title of "ingegnarius"
while in his second stay in Florence can boast the title of architect and painter.

It is certain that for the advancement of engineering knowledge is availed of personal

knowledge of the Sienese Francesco di Giorgio Martini and his writings: it has a note and a

copy of his Treatise military and civil architecture, designing fortifications with bastions

 bristling with thick corners that can oppose the enemy artillery.

His designs are known for both the dome of the Duomo in Milan for both stately buildings,
for which thinks of hanging gardens and innovative interior solutions, such as stairs double,

quadruple and inside the houses "with mill'll generate wind every time the state;
I will raise the water surgitiva and fresh, which will PEL half of the tables divided [...]
and more water will run PEL garden, adacquando them pomeranci and cedars to their needs [...]
farassi through the mill, many conduits of water for the house, and sources in different lochia,
and any transit where, who you will, for all parties under the water to jump upward. "

But it also deals with the modern conception of "a polished stable" to arrive at imagine an

ideal city, structured multi-level road, where the lower level flowed wagons,
and in the upper one had comfortable for pedestrians.

In 1502 Leonardo da Vinci produced a drawing of a single span bridge of 300 meters,
as part of a civil engineering project for Ottoman Sultan Bayazed II.
It was expected that a pylon of the bridge would be placed on one of the inlet at the mouth

of the Bosphorus, the Golden Horn, but it was never built. The turkish government in

the early years of the twenty-first century has decided to build
a bridge that follows the project Leonardo.

     The personality of Leonardo    

Portrait of Gian Giacomo Caprotti, known as Salai, anonymous,
ca 1495, Vaduz, Aloisi Foundation reported that a contemporary of Leonardo's alleged homosexuality, from anonymous complaint in 1476 (which also ended in acquittal), the lack of relationships with women, notes the ambiguity of Vasari and the relationship with his pupils

Melzi and Caprotti, much younger than him and comely.
The note of Leonardo himself, "it's my first ricordazione of my childhood it seemed to me,

 when I was in the cradle, that a kite to come to me and opened my mouth with its tail,
and many times I percotessi with this tail inside the lips, "derived the interpretation of

Sigmund Freud, in his book A childhood memory of Leonardo da Vinci, in 1910,

as the fantasy of a sex act oral while the kite would androginicamente the mother;
by infantile sexual curiosity of the artist derives his artistic curiosity and scientific
never satisfied and complete.
If homosexuality of Leonardo remains probable although not certain, with all possible

disquisitions on how this may have influenced his art or not , its irreligion and skepticism are indisputable, related to the observations of Vasari, for whom "many were his caprices, that, philosophizing of natural things, expected to understand the properties of herbs, continuing et observing the motion of the sky, the course of the moon and the trends of the sun.

To which made it a spiritual concept yes heretic, which is not approached in any religion, for estimating the adventure much more to be Christian philosopher. "
Aretino, according to its habit of inventing facts that would make uplifting the lives of biografati
for which he felt respect and sympathy, writes that "seeing himself near death, disputing of things Catholic back in the good way, was reduced to the Christian faith with many tears. Hence

confessed and contrite, well if you could not stand up, turned devoutly seize the Blessed

Sacrament forth from 'the bed, " then dying in the arms of King Francis I.
Angel, detail of the Baptism of Christ, ca 1473Molte his notes show contempt for the men of the Church:
the priests who say Mass: "Many fien those who, exercising their art, vestiran you richly,
and this seem to be done according to the custom of 'aprons' [93] on the churches:
"Much will that leave them exercises and the hardships and poverty of life and stuff, and they

will live in wealth buildings and triumphant, showing this to be the means to be a friend of God ";
on selling the Paradise: "Infinite multitude sell public and peacefully things of great price,
without license of the owner of those, and that they were never them, nor in their power,
and this will not provide the human justice "or even" The invisible coins

[The promises of eternal life] faran triumph of those many spenders ";
or the convents, "Those who are dead [the saints], after a thousand years,

fien those expenses that will live for many [Friars] ';
or ironically rites: "Those who go with white with vestimente arrogant movement threatening
with metal and fire [the censer with incense] who did not make them any detriment

 "[and the devotion of the images:
"They will talk about them men alli men who do not feel; orange eyes open and do not see;
speak to those and not fie answered them; chiederan who plows through his ears, and hear not;
faran light to those who are one-eyed. "
Vasari relates of his generosity, his greatness of soul and pride:
"Going to the bench for the provision that every month from Pier Soderini used to take,
the cashier turned to some bags of money, and he turned them to turn,
answering: "I do not have money to painter" 'the pleasantness of his conversation and his love
for the animals, "often going places where you could buy birds, gouging out his hand to the cage,
and pagatogli who sold them the price they had asked, let them fly in the air,

 restoring the lost freedom. "
And his compassion and tenderness towards animals is linked to the news, reported by

Andrea Corsali, that Leonardo was a vegetarian.
But from his writings reflected the image of a man much less sociable than hagiography

Vasari wants to impose:
"If you're alone, you will be all yours, and if you will be accompanied by a single companion,

 you will be through you, and less so the greater will be the indiscretion of his practice.

And if you're more, will fall more in similar incident 'and elsewhere writes that "savage is

 what you save," and in many parts of his manuscripts is distrust and pessimism of

'"human race."
His research and his work was in fact carried out preferably in solitude,
as noted by the vivid description of the master at work at the Last Supper by Matteo Bandello

in his novel LVIII.
It was not usually follow strict rules or habits fixed, preferring to satisfy the creativity and inspiration

of the moment. His almost fanatical search for perfection, with endless tweaks and changes

 (as was the Mona Lisa) stem from his belief that painting, unlike music, is here to stay and

not to run out in the individual performance:
"The painting does not die immediately after its creation as does the music, but long will witness

 your ignorance [...] but if you study [...] let you work that will give you more honor than the

 pecuniary. "
Given the breadth of his interests maximum and unrepeatable event of the Renaissance,
Leonardo, not tied to any city, state or prince, is the first example of the cosmopolitanism of Italian intellectuals, unique in Europe, the expression of a rift between culture and people

 destined to extend to the present day.


     The library of Leonardo  

Leonardo's library was bequeathed to the faithful that Francesco Melzi,
following the death of his teacher, moved from Amboise to his family villa in Vaprio d'Adda,
carrying books, manuscripts and instruments shop belonged to Leonardo.
Of this collection spoke to the Anonymous Gaddiano (1537-1542),

 Giorgio Vasari (1568) and John Paul Lomazzo (1590),
who remember how jealously guarded. Vasari also remembered as a painter in Milan

(Aurelio Luini?) possess some writings of Leonardo "written with the left-handed upside down."
From the analysis of codes Vincian, it was possible to obtain at least a part of the texts

possessed by Leonardo for his studies.
In 1504 it declared in one of his writings to have over a hundred books
more than fifty collections of his writings: twenty-five "small" sixteen "biggest"
two "major", you are in "parchment" and one with "coverta suede green."

Lost original by Leonardo   


It is not difficult to imagine the rapid dispersion of the large amount of books,
sheets and notes once owned by Leonardo.
The heirs of Francesco Melzi in fact sold all the assets left to him by his master,
giving rise to the dispersion of Leonardo.

     The manuscripts    

In the characteristic mirror writing, turning from right to left, that they can be read easily
only by placing the sheets in front of a mirror, the manuscripts of Leonardo, data inherited by Francesco Melzi, They reached after the death of these to the sculptor Pompeo Leoni that,

 in the trader more easily, divided them into different groups, changing its original appearance.
Collected largely in the seventeenth century by Count Galeazzo Milanese Arconati
were donated to the Biblioteca Ambrosiana in Milan from which they were transferred

 in 1796 in Paris, from where he returned to Milan after the fall of Napoleon,

the only Codex Atlanticus, while others, to an error of the Distributor Austrian,

remained at the Institut de France.
Other codes had long since ended up in England.
Today there are more than 8,000 sheets of notes (over 16,000 pages)
with many tens of thousands of drawings left by Leonardo, but it is believed that only

a small part of what he has written and illustrated. Some think that he wrote 60,000,

 perhaps 100,000 pages, now lost.
But maybe something is still there, buried in some ancient archive in 1966, for example,

 were found two new codes in Madrid. It is written pages about "casting", so much so that experts Leonardo said:
"seem to hear him talk like a tape recorder.


        Leonardo writer      
Leonardo's prose is considered among the best of the Italian Renaissance;
devoid of any rhetorical fireworks and sounds, it's all responsive to things referring to

the spoken language, it has color, robustness, conciseness, in order to give energy and fluency expression.
For Francesco Flora, inventor Leonardo proved also in writing, so as to appear more modern

 than its predecessors so that his contemporaries:
"We will not say more on Boccaccio father of Italian prose [...] as a whole the prose of

Boccaccio tends to the syntax lyric [...] Was the prose of the Convivio Dante and of some

 chronicles and treatises, but the great prose, the first prose largest in Italy,
is to be found in the writings of Leonardo: the highest prose of the early Renaissance,
although in completely alien to the humanistic model and freely exemplified the common

 speech. " His most important work is the Treatise on Painting, posthumous collection

edited by an anonymous student.


        The features of Leonardo     


Three-dimensional representation of the self-magnification scale of

Leonardo 10:1 -Viareggio 2012Le features of Leonardo is known for an alleged portrait senile
dating back to around 1515 and preserved in the Royal Library of Turin. The work, from which

 they derive other portraits ideals, is now part of the collective.
On the features of Leonardo's age young or mature are some identifying assumptions

 in his works or of other artists, as the young man standing at the far right of the

Adoration of the Magi, in Verrocchio's David, or the figure of Plato in the School of Athens by Raphael.
There are also a variety of sources which, while not describe his physical appearance

 in a precise manner, speak of his ways and celebrate its beauty. For example, the Gaddiano Anonymous wrote: "[Nature] not only the beauty of the body, that granted him very well,

 he turned to endow it, but many rare virtues anchora it turned teacher. [...]
It was a beautiful person, proportioned, et gratiata beautiful appearance.

 beggar wore a pink short to the knee, which then s'usavano the vestiri long haveva until

 mezo in a beautiful chest capellaia et ringed et well composed. "
Vasari took the aspect docile and loving of his character:
"He with the splendor of its air, which was beautiful, sad mood calmed each,
and the words turned to each indurata yes no intention et al. He believed with all his

forces violent fury.
[...] With the donations collected and was tending his every friend, poor and rich,

 but that he had talent and virtue.
[...] For the great gift that was really Fiorenza in the birth of Leonardo,

and loss rather than infinite in his death. "


The critical success of the painter   

The critical success of the painter was immediate and has never suffered blackouts.
Already for the Vasari "wanted so much the nature favor, that wherever you turned the thought,

the brain and the mind, showed so much divinity in things and in his readiness to perfection, divinity, goodness, vagueness and grace no one else was ever the same. " For the Lomazzo
"Leonardo in giving the light shows that habbi always feared not to give too clear,
reserve it for a better spot and he has tried to intense dark, ritrovar them to the extreme.
Waves with such art has achieved in the faces and bodies, that has really done wonders,

 all you can do nature.
In this part has been superior to all, so that in a word, we may say that 'the light of

Leonardo is divine. "
Not by chance, the historic Arezzo ascribed the start of the "Modern Way"
placing it at the beginning of the third part of the screw.
For Goethe, "Leonardo reveals great primarily as a painter.
Regularly and perfectly formed, it appeared, against the common humanity,

a perfect example of it.
As the clarity and insight of the eye refers more properly to the intellect,
such clarity and intelligence were of the artist. Did not indulge last
impetus of its original and unparalleled talent, slowing momentum every spontaneous

and random, just wanted every part was considered and rimeditato. "
For the painter Delacroix, Leonardo "arrives without error, without weakness,
without exaggeration, almost a leap, then naturalism judicious and wise,
away also servile imitation and a perfect vacuum and chimerical.
Strange thing! The most methodical of men, who among the masters of his time was more

occupied methods of execution, which taught them with such precision that the works of his best students are always confused with his, this man, whose manner is so typical, not rhetoric.

Always attentive to nature, consulting it relentlessly, never imitates himself,

 the most learned of the masters is also the most naive, and none of his followers,

Michelangelo and Raphael, as he deserves such praise. "
Hippolyte Taine wrote that "there is perhaps the world an example of genius so universal,

inventive, unable to be satisfied, greedy of infinity and of course refined, leaning forward,
beyond his own century and the following ones. His figures express a feeling and an

incredible spirit;
overflow of ideas and feelings unexpressed. Next to them, the characters of Michelangelo

that athletes are not heroic;
virgins of Raphael are nothing but placid girls, whose soul is not asleep he lived.
Her, feel and think with each stroke of the face and countenance;
it takes some time to establish a dialogue with them, not that the sentiment they express is too poorly defined;
on the contrary, it comes from the whole aspect, but it is too thin, too complicated, too far out and beyond the town, impenetrable and inexplicable.
The stillness and the silence they leave guess two or three overlapping thoughts,
and others, concealed behind the farthest; dimly glimpsed this world intimate and secret
as a delicate unknown vegetation below the depth of the water is transparent. "
For Wölfflin, "is the first artist to systematically studied the proportions in the bodies of men
and animals and has become aware of the mechanical ratios, in going, climbing,
in lifting and carrying objects;
but also the one who discovered the most distant facial characteristics, meditating on the expression of a coordinated movements of the soul.
The painter is for him the clear eye of the world, dominating all things visible. "
The Virgin of Leonardo roccePer Octave Siren "was Florence to the core,

 although most sagacious, more flexible,
more intelligent than its predecessors. Later became interested in the problems of painting

 as they she was studying scientific ones, which results in the presence in his art, new trends
and traits unknown to his contemporaries. The transition from fine detail, hard-edged,
the gradations of light and shade, the fullness of sfumato, summarizes a general trend in Renaissance painting;
but what about Leonardo did not put into effect until two or three generations,
he became mature in the space of twenty or thirty years. "
Emilio Cecchi "he originated a painting unsurpassed intensity, where the rough chiaroscuro

 and luminosity of Masaccio is ingeniously deduced in a number of plastic expression,
if once again we must recall the memory of Greece, you can not compare that to the

 mysterious and sublime grace of the sculpture of Praxiteles »
André Chastel, having made their insecurity and ambiguity of human life,
"the meaning of an ambiguous position between the man and the exquisite horrible,

between what is certain and what is illusory, Leonardo was more pronounced in the years:

 there is in his painting a parallel development of chiaroscuro.
The principle of it was primarily the interest of contrast that enhances the opposite terms [...]
he is so pleased with the sweet lights to slide imperceptibly into the shadows delicious,
thus overcoming the conflict between design and molded [...] By declaring that, as Giotto and Masaccio, should only be children of nature, he means to say that all the problems

of painting, in all grades, must be rethought entirely. The gradient resolves the difficulties

of drawing and get the unity of the forms within the space enveloping atmosphere. "
For Argan Finally, in Leonardo "everything is immanence. The experience of reality

must be direct, not affected by any a priori certainty: not the authority of dogma and scripture,
not the logic of philosophical systems, not the perfection of the ancients.

But the reality is immense, we can take it only in special phenomena [...] and the

 phenomenon is when, in particular, manifests the totality of reality. " If the art of Michelangelo dominates the moral sentiment, for which by nature must redeem our spiritual existence

 with which we are linked to God, Leonardo predominates in the feeling of nature,

"that for which we feel the pulsating rhythm of our lives in unison with that of the cosmos. "

          Leonardo "esoteric"    


Leonardo has always been a character shrouded in mystery,
both because of his unique personality, to the incredible versatility of his interests,
that arouse curiosity today.
Not lacking in his character some sides 'dark', that can lead to uncertainty and perplexity,
as the methods by which he could to carry out investigations anatomical or his approach to the material and immanent, almost agnostic, so forerunner of time.
To this must be added the cryptic writing from right to left and the habit, for fun,
to invent code phrases, anagrams and puzzles.
These and other factors have created a huge reservoir from which to draw to reread his human,
as well as artistic and intellectual, according to new interpretations, sometimes real misrepresentation or exploitation that have little to do with the true meaning
of his complex personality.
The most striking case is emblematic and certainly in the novel

The Da Vinci Code by Dan Brown, with its resounding success in publishing and media

around the world.
In it, including puzzles, murder and a dense web of history, esotericism, art and theology,
tells of a shocking secret to Christianity handed down over the centuries by a sort of

secret society, the Priory of Sion, but kept hidden by the ecclesiastical hierarchy and,

 in recent times, by Opus Dei.
The secret concerns the human nature of Christ, his marriage to Mary Magdalene
(Symbolized by the Holy Grail itself) and the existence of their offspring.
Between historical events actually occurred and other pure fantasy, it is argued that

Leonardo coated the office of Grand Master of the Priory, hiding in some of his works, through innuendo and coded messages, a number of references to his active participation and secret.
Among the various works chosen by Dan Brown are the Mona Lisa and the Last Supper:
the first conceals a self-portrait of the artist dressed as women, the second would be a representation the "secret", with John, who would be identified as Mary Magdalene.
Despite the endless controversy generated by the book, the questionable historical

reconstructions and documentary and the naive errors iconographic curiosity and almost

maniacal attention generated on almost everything
regarding Leonardo had after all the merit of bringing into the spotlight the genius of Vinci,
with exhibitions, conferences, surveys and documentaries passed on all the world's media

     Leonardo and the Shroud of Turin  

According to some scholars Leonardo would be the author of the Holy Shroud.
Victory for Haziel, was drawn using a red-hot iron on an old canvas, with a self-portrait

for the face.
The technique, according to the Haziel, reminiscent of Leonardo's sfumato.
The Haziel also published in 1998 a book about it, The Passion According to Leonardo.
Even an American artist Lillian Schwartz says that the Shroud is a self-portrait of Leonardo.
Schwartz used the computer-generated images to support the similarity of the

Shroud with self-portrait of Leonardo.
The Schwartz is the painter who claimed to be in the eighties even the Mona Lisa a

self-portrait of Leonardo.
However, according to John Jackson, director of a research center on the Holy Shroud in the

 United States, the hypothesis of false Leonardo unfounded: he argues that there is a commemorative medallion, dating from the mid-fourteenth century and preserved in the

Museum of Cluny, so the first news about the Shroud of about 100 years precede the birth of Leonardo.
