Leonardo di ser Piero da Vinci[b] (15 April 1452 – 2 May 1519) was an Italian polymath of the High Renaissance who was active as a painter, draughtsman, engineer, scientist, theorist, sculptor and architect. An illegitimate son of Piero Fruosino di Antonio da Vinci, a Florentine notary, and Caterina, a peasant girl, he was brought up on the family estate in Anchiano by his paternal grandfather. His father married a sixteen-year old girl, Albiera, with whom Leonardo was close, but who died young. Leonardo was the oldest of 12 siblings and his family never treated his illegitimacy as a stigma. At the age of 14 Leonardo moved to Florence to begin an apprenticeship with Andrea del Verrocchio, an artist who had been a student of Early Renaissance master Donatello.
