What's in an Italian last name? Ask Leonardo da Vinci. Piero della Francesca. Alessandro Botticelli. Or Domenico Ghirlandaio. They were all great artists of the Italian Renaissance, and their surnames paint a picture too.
On the Map
Historically, many Italian last names were based on where a person lived or was born. Leonardo da Vinci's family was from Vinci, a town in eastern Tuscany—hence his last name, meaning "from Vinci." Ironically, during his lifetime, he was referred to solely by his first name.
