Why do you call Raphael by his first name instead of his last name?
Many great artists, such as Michelangelo and Raphael, usually take their surnames by their first names. Da Vinci is not the surname of Da Vinci, but he was born in Wenxi City. Leonardo di ser Piero da Vinci's full name is Leonardo, the son of Messer Piero in Wenxi. His father's name is Sir Piero.
