He was nobody's official son - and became the most complete mind the world has ever recorded.
On April 15, 1452, in the hillside village of Vinci in the Republic of Florence, a woman named Caterina gave birth to a boy outside of marriage. His father, Ser Piero da Vinci, was a Florentine notary - a respectable man with a career to protect and a legitimate family to maintain. The child was acknowledged but not legitimized. He could not inherit his father's profession. He could not join the major guilds. He could not attend university. Society had already written the first sentence of his story, and it said: you are less than the others.
At approximately 14, Ser Piero brought him to Florence and placed him in the workshop of Andrea del Verrocchio - one of the greatest artists in the city. Within a few years, according to the account passed down by Giorgio Vasari, Verrocchio saw that his pupil had already surpassed him. He put down his brush and never painted again.
At 30, Leonardo left Florence for Milan. He entered the court of Ludovico Sforza not as a painter but as a military engineer, a designer of weapons and festivals and waterways. He painted The Lady with an Ermine. He painted The Virgin of the Rocks. And between 1495 and 1498, on the refectory wall of Santa Maria delle Grazie, he painted The Last Supper - a fresco so revolutionary in its composition, its psychology, its use of light and gesture, that 500 years of art history have never caught up with it.
IT IS STILL ON THAT WALL IN MILAN TODAY.
But here's what nobody talks about when they tell the Leonardo story.
While he was painting, he was also writing. Filling notebooks - in mirror script, left to right in reverse, so that the pages could only be read by holding them to a glass. Anatomy: he dissected more than thirty human bodies, drew every muscle, every nerve, every organ with a precision that would not be matched for 200 years. Hydraulics. The flight of birds. The movement of water. The geology of mountains. The mechanics of the human eye. Jokes. Grocery lists. A plan for a flying machine. A plan for a tank. A design for a solar power concentrator.
SEVEN THOUSAND PAGES. ALMOST NONE OF IT PUBLISHED IN HIS LIFETIME.
In 1499, the French invaded Milan and Leonardo fled. He spent the next years moving - Venice, Florence, Rome, back north. He began the Mona Lisa around 1503 and worked on it for years, carrying it with him everywhere, never declaring it finished, never giving it to the man who commissioned it.
In 1516, King Francis I of France invited him to the Loire Valley as Premier Painter, Engineer, and Architect to the French Crown. Leonardo was 64. He packed the Mona Lisa and the notebooks and crossed the Alps for the last time.
He died on May 2, 1519 - 507 years ago today - at the Château du Clos Lucé in Amboise, France. According to the account of Giorgio Vasari, Francis I was at his side.
Italy's greatest son died in France. The notebooks passed to his young assistant Francesco Melzi, who preserved them. They were not fully studied for centuries. The anatomical drawings were rediscovered in the 1700s. Engineers were still finding unbuilt inventions in the notebooks in the 1900s.
He spent his life filling the future with answers - and the future kept finding them, one century at a time.
Some men are ahead of their time. Leonardo da Vinci was ahead of every time that has come since.
