The illegitimate son of a 25-year-old notary, Ser Piero, and peasant girl, Caterina, Leonardo was born on April 15, 1452, in Vinci, Italy, just outside Florence. His father took custody of the little fellow shortly after his birth, while his mother married someone else and moved to a neighboring town. They kept on having kids, although not with each other, and they eventually supplied him with a total of 17 half sisters and brothers. Growing up in his father's Vinci home, Leonardo had access to scholarly texts owned by family and friends. He was also exposed to Vinci's longstanding painting tradition, and when he was about 15 his father apprenticed him to the renowned workshop of Andrea del Verrochio in Florence. Even as an apprentice, Leonardo demonstrated his colossal talent. Indeed, his genius seems to have seeped into a number of pieces produced by the Verrocchio's workshop from the period 1470 to 1475. Leonardo got his start as an artist around 1469. Verocchio's specialty was perspective, which artists had only recently begun to get the hang of, and Leonardo quickly mastered its challenges.

For example, one of Leonardo's first big breaks was to paint an angel in Verrochio's "Baptism of Christ," and Leonardo was so much better than his master's that Verrochio allegedly resolved never to paint again. Leonardo stayed in the Verrocchio workshop until 1477 when he set up a shingle for himself. In search of new challenges and the big bucks, he entered theservice of the Duke of Milan in 1482, abandoning his first commission in Florence, "The Adoration of the Magi". He spent 17 years in Milan, leaving only after Duke Ludovico Sforza's fall from power in 1499. It was during these years that Leonardo hit his stride, reaching new heights of scientific andartistic achievement. One of his most popular early works, "The Adoratio...
