Leonardo da Vinci's lifes

Leonardo da Vinci

Leonardo di ser Piero da Vinci ( pronunciation (help·info)) (April 15, 1452 – May 2, 1519, Old Style) was an Italian Renaissance polymath: painter, sculptor, architect, musician, scientist, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist and writer whose genius, perhaps more than that of any other figure, epitomized the Renaissance humanist ideal. Leonardo has often been described as the archetype of the Renaissance Man, a man of "unquenchable curiosity" and "feverishly inventive imagination".[1] He is widely considered to be one of the greatest painters of all time and perhaps the most diversely talented person ever to have lived.[2] According to art historian Helen Gardner, the scope and depth of his interests were without precedent and "his mind and personality seem to us superhuman, the man himself mysterious and remote".[1] Marco Rosci points out, however, that while there is much speculation about Leonardo, his vision of the world is essentially logical rather than mysterious, and that the empirical methods he employed were unusual for his time.[3]
Born out of wedlock to a notary, Piero da Vinci, and a peasant woman, Caterina, at Vinci in the region of Florence, Leonardo was educated in the studio of the renowned Florentine painter, Verrocchio. Much of his earlier working life was spent in the service of Ludovico il Moro in Milan. He later worked in Rome, Bologna and Venice, and he spent his last years in France at the home awarded him by Francis I.

Life

Childhood, 1452–1466
Leonardo was born on April 15, 1452 (Old Style), "at the third hour of the night"[nb 5] in the Tuscan hill town of Vinci, in the lower valley of the Arno River in the territory of the Medici-ruled Republic of Florence.[8] He was the out-of-wedlock son of the wealthy Messer Piero Fruosino di Antonio da Vinci, a Florentine legal notary, and Caterina, a peasant.[7][9][nb 6] Leonardo had no surname in the modern sense, “da Vinci” simply meaning “of Vinci”: his full birth name was "Lionardo di ser Piero da Vinci", meaning "Leonardo, (son) of (Mes)ser Piero from Vinci".[8] The inclusion of the title "ser" indicated that Leonardo's father was a gentleman.
Little is known about Leonardo's early life. He spent his first five years in the hamlet of Anchiano in the home of his mother, then from 1457 he lived in the household of his father, grandparents and uncle, Francesco, in the small town of Vinci. His father had married a sixteen-year-old girl named Albiera, who loved Leonardo but died young.[10] When Leonardo was sixteen his father married again, to twenty-year-old Francesca Lanfredini. It was not until his third and fourth marriages that Ser Piero produced legitimate heirs.[11]

Professional life, 1476–1513
Florentine court records of 1476 show that Leonardo and three other young men were charged with sodomy and acquitted.[9][nb 10] From that date until 1478 there is no record of his work or even of his whereabouts.[21] In 1478 he left Verrocchio's studio and was no longer resident at his father's house. One writer, the "Anonimo" Gaddiano claims that in 1480 he was living with the Medici and working in the Garden of the Piazza San Marco in Florence, a Neo-Platonic academy of artists, poets and philosophers that the Medici had established.[9] In January 1478, he received his first of two independent commissions: to paint an altarpiece for the Chapel of St. Bernard in the Palazzo Vecchio and, in March 1481, The Adoration of the Magi for the Monks of San Donato a Scopeto.[22] Neither commission was completed, the second being interrupted when Leonardo went to Milan.
In 1482 Leonardo, who according to Vasari was a most talented musician,[23] created a silver lyre in the shape of a horse's head. Lorenzo de' Medici sent Leonardo to Milan, bearing the lyre as a gift, to secure peace with Ludovico il Moro, Duke of Milan.[24] At this time Leonardo wrote an often-quoted letter describing the many marvellous and diverse things that he could achieve in the field of engineering and informing Ludovico that he could also paint.
n Cesena, in 1502 Leonardo entered the service of Cesare Borgia, the son of Pope Alexander VI, acting as a military architect and engineer and travelling throughout Italy with his patron.[28] Leonardo created a map of Cesare Borgia's stronghold, a town plan of Imola in order to win his patronage. Maps were extremely rare at the time and it would have seemed like a new concept; upon seeing it, Cesare hired Leonardo as his chief military engineer and architect. Later in the year, Leonardo produced another map for his patron, one of Chiana Valley, Tuscany so as to give his patron a better overlay of the land and greater strategic position. He created this map in conjunction with his other project of constructing a dam from the sea to Florence in order to allow a supply of water to sustain the canal during all seasons.
Leonardo returned to Florence where he rejoined the Guild of St Luke on October 18, 1503, and spent two years designing and painting a mural of The Battle of Anghiari for the Signoria,[28] with Michelangelo designing its companion piece, The Battle of Cascina.[nb 13] In Florence in 1504, he was part of a committee formed to relocate, against the artist's will, Michelangelo's statue of David.[33]
In 1506 Leonardo returned to Milan. Many of his most prominent pupils or followers in painting either knew or worked with him in Milan,[10] including Bernardino Luini, Giovanni Antonio Boltraffio and Marco D'Oggione.[nb 14] However, he did not stay in Milan for long because his father had died in 1504, and in 1507 he was back in Florence trying to sort out problems with his brothers over his father's estate. By 1508 Leonardo was back in Milan, living in his own house in Porta Orientale in the parish of Santa Babila.


Verrocchio's workshop, 1466–1476

In 1466, at the age of fourteen, Leonardo was apprenticed to the artist Andrea di Cione, known as Verrocchio, whose workshop was "one of the finest in Florence".[15] Other famous painters apprenticed or associated with the workshop include Domenico Ghirlandaio, Perugino, Botticelli, and Lorenzo di Credi.[10][16] Leonardo would have been exposed to both theoretical training and a vast range of technical skills[17] including drafting, chemistry, metallurgy, metal working, plaster casting, leather working, mechanics and carpentry as well as the artistic skills of drawing, painting, sculpting and modelling.[18][nb 7]
Much of the painted production of Verrocchio's workshop was done by his employees. According to Vasari, Leonardo collaborated with Verrocchio on his Baptism of Christ, painting the young angel holding Jesus' robe in a manner that was so far superior to his master's that Verrocchio put down his brush and never painted again.[19] On close examination, the painting reveals much that has been painted or touched up over the tempera using the new technique of oil paint, with the landscape, the rocks that can be seen through the brown mountain stream and much of the figure of Jesus bearing witness to the hand of Leonardo.[20] Leonardo may have been the model for two works by Verrocchio: the bronze statue of David in the Bargello and the Archangel Raphael in Tobias and the Angel.



Florence — Leonardo's artistic and social background
Florence, at the time of Leonardo's youth, was the centre of Christian Humanist thought and culture.[42] Leonardo commenced his apprenticeship with Verrocchio in 1466, the year that Verrocchio's master, the great sculptor Donatello, died. The painter Uccello, whose early experiments with perspective were to influence the development of landscape painting, was a very old man. The painters Piero della Francesca and Fra Filippo Lippi, sculptor Luca della Robbia, and architect and writer Leon Battista Alberti were in their sixties. The successful artists of the next generation were Leonardo's teacher Verrocchio, Antonio Pollaiuolo and the portrait sculptor, Mino da Fiesole whose lifelike busts give the most reliable likenesses of Lorenzo Medici's father Piero and uncle Giovanni.[43][44][45][46]
Leonardo's youth was spent in a Florence that was ornamented by the works of these artists and by Donatello's contemporaries, Masaccio whose figurative frescoes were imbued with realism and emotion and Ghiberti whose Gates of Paradise, gleaming with gold leaf, displayed the art of combining complex figure compositions with detailed architectural backgrounds. Piero della Francesca had made a detailed study of perspective,[47] and was the first painter to make a scientific study of light. These studies and Alberti's Treatise[48] were to have a profound effect on younger artists and in particular on Leonardo's own observations and artworks.

Old age, 1513–1519
From September 1513 to 1516, Leonardo spent much of his time living in the Belvedere in the Vatican in Rome, where Raphael and Michelangelo were both active at the time.[34] In October 1515, Francis I of France recaptured Milan.[22] On December 19, Leonardo was present at the meeting of Francis I and Pope Leo X, which took place in Bologna.[10][35][36] Leonardo was commissioned to make for Francis a mechanical lion which could walk forward, then open its chest to reveal a cluster of lilies.[37][nb 15] In 1516, he entered François' service, being given the use of the manor house Clos Lucé[nb 16] near the king's residence at the royal Château d'Amboise. It was here that he spent the last three years of his life, accompanied by his friend and apprentice, Count Francesco Melzi, and supported by a pension totalling 10,000 scudi.
Some twenty years after Leonardo's death, Francis was reported by the goldsmith and sculptor Benevenuto Cellini as saying: "There had never been another man born in the world who knew as much as Leonardo, not so much about painting, sculpture and architecture, as that he was a very great philosopher.

Assistants and pupils
Gian Giacomo Caprotti da Oreno, nicknamed Salai or Il Salaino ("The Little Unclean One" i.e., the devil), entered Leonardo's household in 1490. After only a year, Leonardo made a list of his misdemeanours, calling him "a thief, a liar, stubborn, and a glutton", after he had made off with money and valuables on at least five occasions and spent a fortune on clothes.[60] Nevertheless, Leonardo treated him with great indulgence, and he remained in Leonardo's household for the next thirty years.[61] Salai executed a number of paintings under the name of Andrea Salai, but although Vasari claims that Leonardo "taught him a great deal about painting",[37] his work is generally considered to be of less artistic merit than others among Leonardo's pupils, such as Marco d'Oggione and Boltraffio. In 1515, he painted a nude version of the Mona Lisa, known as Monna Vanna.[62] Salai owned the Mona Lisa at the time of his death in 1525, and in his will it was assessed at 505 lire, an exceptionally high valuation for a small panel portrait.[63]
In 1506, Leonardo took on another pupil, Count Francesco Melzi, the son of a Lombard aristocrat, who is considered to have been his favourite student. He travelled to France with Leonardo and remained with him until Leonardo's death.[10] Melzi inherited the artistic and scientific works, manuscripts, and collections of Leonardo and administered the estate.

Early works
Leonardo's early works begin with the Baptism of Christ painted in conjunction with Verrocchio. Two other paintings appear to date from his time at the workshop, both of which are Annunciations. One is small, 59 centimetres (23 in) long and 14 centimetres (5.5 in) high. It is a "predella" to go at the base of a larger composition, in this case a painting by Lorenzo di Credi from which it has become separated. The other is a much larger work, 217 centimetres (85 in) long.[66] In both these Annunciations, Leonardo used a formal arrangement, such as in Fra Angelico's two well known pictures of the same subject, of the Virgin Mary sitting or kneeling to the right of the picture, approached from the left by an angel in profile with rich flowing garment, raised wings and bearing a lily. Although previously attributed to Ghirlandaio, the larger work is now generally attributed to Leonardo.


Painting

Despite the recent awareness and admiration of Leonardo as a scientist and inventor, for the better part of four hundred years his fame rested on his achievements as a painter and on a handful of works, either authenticated or attributed to him that have been regarded as among the masterpieces.[64]
These paintings are famous for a variety of qualities which have been much imitated by students and discussed at great length by connoisseurs and critics. Among the qualities that make Leonardo's work unique are the innovative techniques that he used in laying on the paint, his detailed knowledge of anatomy, light, botany and geology, his interest in physiognomy and the way in which humans register emotion in expression and gesture, his innovative use of the human form in figurative composition, and his use of the subtle gradation of tone. All these qualities come together in his most famous painted works, the Mona Lisa, the Last Supper and the Virgin of the Rocks.

Paintings of the 1480s
In the 1480s Leonardo received two very important commissions and commenced another work which was also of ground-breaking importance in terms of composition. Two of the three were never finished, and the third took so long that it was subject to lengthy negotiations over completion and payment. One of these paintings is that of St. Jerome in the Wilderness. Bortolon associates this picture with a difficult period of Leonardo's life, as evidenced in his diary: "I thought I was learning to live; I was only learning to die."[10]
Although the painting is barely begun, the composition can be seen and it is very unusual.[nb 21] Jerome, as a penitent, occupies the middle of the picture, set on a slight diagonal and viewed somewhat from above. His kneeling form takes on a trapezoid shape, with one arm stretched to the outer edge of the painting and his gaze looking in the opposite direction. J. Wasserman points out the link between this painting and Leonardo's anatomical studies.[69] Across the foreground sprawls his symbol, a great lion whose body and tail make a double spiral across the base of the picture space. The other remarkable feature is the sketchy landscape of craggy rocks against which the figure is silhouetted.


Paintings of the 1490s
Leonardo's most famous painting of the 1490s is The Last Supper, painted for the refectory of the Convent of Santa Maria della Grazie in Milan. The painting represents the last meal shared by Jesus with his disciples before his capture and death. It shows specifically the moment when Jesus has just said "one of you will betray me". Leonardo tells the story of the consternation that this statement caused to the twelve followers of Jesus.[16]
The novelist Matteo Bandello observed Leonardo at work and wrote that some days he would paint from dawn till dusk without stopping to eat and then not paint for three or four days at a time.[72] This was beyond the comprehension of the prior, who hounded him until Leonardo asked Ludovico to intervene. Vasari describes how Leonardo, troubled over his ability to adequately depict the faces of Christ and the traitor Judas, told the Duke that he might be obliged to use the prior as his model.


Paintings of the 1500s
Among the works created by Leonardo in the 16th century is the small portrait known as the Mona Lisa or "la Gioconda", the laughing one. In the present era it is arguably the most famous painting in the world. Its fame rests, in particular, on the elusive smile on the woman's face, its mysterious quality brought about perhaps by the fact that the artist has subtly shadowed the corners of the mouth and eyes so that the exact nature of the smile cannot be determined. The shadowy quality for which the work is renowned came to be called "sfumato" or Leonardo's smoke. Vasari, who is generally thought to have known the painting only by repute, said that "the smile was so pleasing that it seemed divine rather than human; and those who saw it were amazed to find that it was as alive as the original".[77][nb 22]
Other characteristics found in this work are the unadorned dress, in which the eyes and hands have no competition from other details, the dramatic landscape background in which the world seems to be in a state of flux, the subdued colouring and the extremely smooth nature of the painterly technique, employing oils, but laid on much like tempera and blended on the surface so that the brushstrokes are indistinguishable.[nb 23] Vasari expressed the opinion that the manner of painting would make even "the most confident master ... despair and lose heart."[80] The perfect state of preservation and the fact that there is no sign of repair or overpainting is rare in a panel painting of this date.[81]
In the painting Virgin and Child with St. Anne the composition again picks up the theme of figures in a landscape which Wasserman describes as "breathtakingly beautiful"[82] and harkens back to the St Jerome picture with the figure set at an oblique angle. What makes this painting unusual is that there are two obliquely set figures superimposed. Mary is seated on the knee of her mother, St Anne. She leans forward to restrain the Christ Child as he plays roughly with a lamb, the sign of his own impending sacrifice.[16] This painting, which was copied many times, influenced Michelangelo, Raphael, and Andrea del Sarto,[83] and through them Pontormo and Correggio. The trends in composition were adopted in particular by the Venetian painters Tintoretto and Veronese.


Scientific studies

Leonardo's approach to science was an observational one: he tried to understand a phenomenon by describing and depicting it in utmost detail and did not emphasize experiments or theoretical explanation. Since he lacked formal education in Latin and mathematics, contemporary scholars mostly ignored Leonardo the scientist, although he did teach himself Latin. In the 1490s he studied mathematics under Luca Pacioli and prepared a series of drawings of regular solids in a skeletal form to be engraved as plates for Pacioli's book De Divina Proportione, published in 1509.[16]
It appears that from the content of his journals he was planning a series of treatises to be published on a variety of subjects. A coherent treatise on anatomy was said to have been observed during a visit by Cardinal Louis 'D' Aragon's secretary in 1517.[89] Aspects of his work on the studies of anatomy, light and the landscape were assembled for publication by his pupil Francesco Melzi and eventually published as Treatise on Painting by Leonardo da Vinci in France and Italy in 1651 and Germany in 1724,[90] with engravings based upon drawings by the Classical painter Nicholas Poussin.[citation needed] According to Arasse, the treatise, which in France went into sixty two editions in fifty years, caused Leonardo to be seen as "the precursor of French academic thought on art".

Journals and notes
Renaissance humanism recognized no mutually exclusive polarities between the sciences and the arts, and Leonardo's studies in science and engineering are as impressive and innovative as his artistic work.[16] These studies were recorded in 13,000 pages of notes and drawings, which fuse art and natural philosophy (the forerunner of modern science), made and maintained daily throughout Leonardo's life and travels, as he made continual observations of the world around him.[16]
Leonardo's writings are mostly in mirror-image cursive. The reason may have been more a practical expediency than for reasons of secrecy as is often suggested. Since Leonardo wrote with his left hand, it is probable that it was easier for him to write from right to left.
His notes and drawings display an enormous range of interests and preoccupations, some as mundane as lists of groceries and people who owed him money and some as intriguing as designs for wings and shoes for walking on water. There are compositions for paintings, studies of details and drapery, studies of faces and emotions, of animals, babies, dissections, plant studies, rock formations, whirlpools, war machines, helicopters and architecture.

Engineering and inventions
During his lifetime Leonardo was valued as an engineer. In a letter to Ludovico il Moro he claimed to be able to create all sorts of machines both for the protection of a city and for siege. When he fled to Venice in 1499 he found employment as an engineer and devised a system of moveable barricades to protect the city from attack. He also had a scheme for diverting the flow of the Arno River, a project on which Niccolò Machiavelli also worked.[94][95] Leonardo's journals include a vast number of inventions, both practical and impractical. They include musical instruments, hydraulic pumps, reversible crank mechanisms, finned mortar shells, and a steam cannon.[10][16]
In 1502, Leonardo produced a drawing of a single span 720-foot (220 m) bridge as part of a civil engineering project for Ottoman Sultan Beyazid II of Constantinople. The bridge was intended to span an inlet at the mouth of the Bosporus known as the Golden Horn. Beyazid did not pursue the project because he believed that such a construction was impossible. Leonardo's vision was resurrected in 2001 when a smaller bridge based on his design was constructed in Norway.[96] On May 17, 2006, the Turkish government decided to construct Leonardo's bridge to span the Golden Horn.

Anatomy
Leonardo's formal training in the anatomy of the human body began with his apprenticeship to Andrea del Verrocchio, who insisted that all his pupils learn anatomy. As an artist, he quickly became master of topographic anatomy, drawing many studies of muscles, tendons and other visible anatomical features.
As a successful artist, he was given permission to dissect human corpses at the Hospital of Santa Maria Nuova in Florence and later at hospitals in Milan and Rome. From 1510 to 1511 he collaborated in his studies with the doctor Marcantonio della Torre. Leonardo made over 200 pages of drawings and many pages of notes towards a treatise on anatomy. These papers were left to his heir, Francesco Melzi, for publication, a task of overwhelming difficulty because of its scope and Leonardo's idiosyncratic writing.[92] It was left incomplete at the time of Melzi's death more than fifty years later, with only a small amount of the material on anatomy included in Leonardo's Treatise on painting, published in France in 1632.[16][92] During the time that Melzi was ordering the material into chapters for publication, they were examined by a number of anatomists and artists, including Vasari, Cellini and Albrecht Dürer who made a number of drawings from them.
