Leonardo Da Vinci

Who was Leonardo da Vinci?
· He had a keen eye and quick mind that led him to make important scientific discoveries, yet he never published his ideas.
· He was a gentle vegetarian who loved animals and despised war, yet he worked as a military engineer to invent advanced and deadly weapons.
· He was one of the greatest painters of the Italian Renaissance, yet he left only a handful of completed paintings.

Short Biography of Leonardo da Vinci

Leonardo da Vinci was, in every sense, a Renaissance man. He painted, sculpted, dissected bodies, designed buildings...and much more. He was interested in all branches of human knowledge, and became a skilled practitioner in most of them.
No one in modern culture can hope to master the skills and knowledge required to become an expert in all but a small minority of the arts and sciences. There can be no modern Leonardo da Vinci. But his curiosity about the world is an inspiration to all who have studied his life and works.
This short biography provides a brief overview of Leonardo da Vinci's life, and his main contributions, in the hope that others will be tempted to emulate his breadth of vision and, at least in some fields, his technical expertise.

Leonardo's Early Life
Leonardo da Vinci was born April 15, 1452 in Anchiano, near Vinci, Italy, and died May 2, 1519 in Cloux, France. His father, Ser Piero, was a respected Florentine businessman. His mother, Caterina, was a peasant women. Ser Piero's parents did not consider Caterina a worthy catch, so Ser Piero and Caterina remained unmarried. Caterina later married someone of her own station.
The kindly Ser Piero treated Leonardo as a legitimate son. But, although Ser Piero provided Leonardo with an excellent education, Leonardo did not reveal outstanding abilities as a child.

Leonardo in Florence
At the age of fifteen, Leonardo da Vinci was apprenticed to the artist Andrea del Verrocchio in Florence. Leonardo worked there for fourteen years. Many pen and pencil works remain from this period, including technical sketches of pumps, weapons, and other mechanical objects. Leonardo started to get good commissions, including the Adoration of the Magi for the monastery of San Donato a Scopeto. But this, and other commissions, were left unfinished when he moved to Milan.

The move to Milan
At the age of thirty, Leonardo da Vinci moved to Milan to work for Duke Ludovico. He spent seventeen years there, until Ludovico fell from power in 1499. Leonardo acted as a technical advisor to Ludovico in fields as diverse as architecture, weaponry, hydraulics and engineering. But Leonardo's goals at this time tended to be grandiose and boundless, and much work remained unfinished.
Fortunately for us, Leonardo managed to complete The Last Supper for the monastery of Santa Maria delle Grazie, and The Virgin of the Rocks for the Milanese Confraternity of the Immaculate Conception. But the twelve years Leonardo devoted to creating a monumental bronze statue of a horse were less successful. He created the clay model for the horse, but just before the bronze was to be poured it was diverted to making war cannons. Then Ludovico fell, and the clay model was destroyed in the ensuing war. With the French marching into Milan, Leonardo celebrated the new century by returning home. In January 1500 he left Milan, spent a few months in Mantua and Venice, and then returned to the scene of his apprentice years, Florence.

Leonardo in Florence again
In Florence, Leonardo da Vinci concentrated on mathematical studies before, after two years, taking a ten month break to work for Cesare Borgia. There he invented new cartographic techniques while mapping Borgia’s territories. He also met Nicholas Machiavelli, no doubt picking up some good tips for dealing with high officials!
During this second period in Florence, Leonardo worked on many grand projects. These included plans for a canal to the sea, and a monumental mural in the central square. But the canal remained only a plan, and the mural was never completed. He did, however, complete the Mona Lisa during this time.

Leonardo da Vinci and Science
Also during this second period in Florence, Leonardo da Vinci became especially interested in science, his main impetus being simply to see what was there. His genius enabled him to look deeply into nature-- his artistic vision became a superb tool for detailed scientific investigation.
Art and science combined in his investigations of the human form, which (like everything else he did) was pursued to its limits. He performed dissections in the hospital of Santa Maria Nuova, and provided a comprehensive account of the structure and function of the human body.
Leonardo studied various other natural phenomena, from the flight of birds to the movements of currents, and created vast collections of data pertaining to them.

Leonardo returns to Milan
King Louis XII of France greatly admired Leonardo da Vinci. After requests from Charles d'Amboise, the French governor in Milan, Leonardo returned to Milan in 1508. Leonardo's advice was sought mainly on architectural matters, but his own interests centred on science. His experiments in anatomy proceeded quickly with the collaboration of Marcantonio della Torre, an anatomist from Pavia. Leonardo also continued with botanical, mathematical, optical, mechanical, and geological studies.
Leonardo became convinced that basic mechanical forces produced all organic and inorganic forms, and that they operated in accordance with orderly, harmonious laws. So Leonardo was one of the first to outline a fully scientific vision of nature and the physical universe.

Leonardo is driven to Rome
In 1513 the French were forced to leave Milan, and Leonardo da Vinci moved to Rome. He hoped to find employment through his patron Giuliano de Medici, brother of the pope. Giuliano gave Leonardo rooms in his residence, the Belvedere in the Vatican, and a considerable monthly wage. But the competition was fierce. Donato Bramante was building St. Peter's; Rome was full of young talent. Leonardo could get no commissions and stuck to mathematical studies, experiments, and investigating Rome’s monuments. Feeling underemployed, in 1516, Leonardo accepted the invitation of King Francis I to serve in France and left Italy forever.
The last three years of Leonardo’s life were spent in Cloux (now Clos-Lucé), near the king's summer palace at Amboise on the Loire. Leonardo spent most of his time working on scientific manuscripts and studying anatomy. In a final work, Visions of the End of the World, or Deluge, he depicts the primal forces that rule nature with a growing pessimism. Leonardo died at Cloux and was buried in the church of Saint-Florentin

Leonardo da Vinci - summary
Leonardo da Vinci had an unlimited desire for knowledge, and visual perception was the main tool he used in pursuit of that knowledge. Leonardo believed that only the faculty of sight allowed you to take in experience immediately, correctly, and with certainty.
Seeing was paramount for Leonardo, which is why he excelled in the visual arts. But his penetrating vision was used to further many other branches of knowledge, including anatomy and engineering.

Leonardo described and sketched ideas for many inventions hundreds of years ahead of their time. But it seems the very few of these were ever built and tested during his life. Though his notes suggest that he wished to organize and publish his ideas, he died before he could accomplish this important goal. After his death, his notebooks were hidden away, scattered, or lost, and his wonderful ideas were forgotten. Centuries passed before other inventors came up with similar ideas and brought them to practical use. Click on the pictures of the modern inventions to see how Leonardo envisioned them in his notebooks over 500 years ago.

Here is a modern parachute used in the sport of skydiving. The first reported successful parachute jump was made from the top of a tower in France in 1783.

This is a U.S. Navy helicopter capable of carrying heavy loads. The first helicopter that could carry a person was designed and flown by Paul Cornu in 1907.

This drawing shows a modern army tank. Tanks were first used during World War One in Cambrai, France in 1917.

With its landing gear down, this U.S. Navy plane is ready to take off or land. Once the plane is in the air, the landing gear folds up to give the plane a more efficient, streamlined shape. The first airplane with retractable landing gear was built in 1933

Modern SCUBA divers can swim freely underwater while breathing compressed air from tanks on their backs. Jacques-Yves Cousteau and Emile Gagnon invented this self-contained breathing apparatus in 1943.

In fact Leonardo has been one of the most important minds in history. We can find in his books research on anatomy, civil and military engineers, architecture, hydraulics, astronomy, geology....He is “a man of Renaissance” good at art and also good at science.
Some of his work is kept in a museum in his hometown.

He filled many pages with his ideas and sketches, but only some of them have come to us. we know how intelligent he was, and we know how particular he also was; that’s why Leonardo is always on the news, because from time to time someone appears saying, even proving, to have found a hidden message from Leonardo in one of his works.
Do those hidden messages exist or not? What we really know is that we don’t know much about his private life and believes.
