Leonardo da Vinci
Early period: Florence
Leonardo’s parents were unmarried at the time of his birth. His father, Ser Piero, was a Florentine notary and landlord, and his mother, Caterina, was a young peasant woman who shortly thereafter married an artisan. Leonardo grew up on his father’s family’s estate, where he was treated as a “legitimate” son and received the usual elementary education of that day: reading, writing, and arithmetic. Leonardo did not seriously study Latin, the key language of traditional learning, until much later, when he acquired a working knowledge of it on his own. He also did not apply himself to higher mathematics—advanced geometry and arithmetic—until he was 30 years old, when he began to study it with diligent tenacity.
Leonardo’s artistic inclinations must have appeared early. When he was about 15, his father, who enjoyed a high reputation in the Florence community, apprenticed him to artist Andrea del Verrocchio. In Verrocchio’s renowned workshop Leonardo received a multifaceted training that included painting and sculpture as well as the technical-mechanical arts. He also worked in the next-door workshop of artist Antonio Pollaiuolo. In 1472 Leonardo was accepted into the painters’ guild of Florence, but he remained in his teacher’s workshop for five more years, after which time he worked independently in Florence until 1481. There are a great many superb extant pen and pencil drawings from this period, including many technical sketches—for example, pumps, military weapons, mechanical apparatus—that offer evidence of Leonardo’s interest in and knowledge of technical matters even at the outset of his career.
