Sandro —, Italian painter whose works include The Birth of Venus and Venus and Mars (10)

I believe the answer is:
botticelli
(Other definitions for botticelli that I've seen before include "Italian painter of The Birth of Venus, d. 1510" , "Italian painter, 1445-1510" , "Florentine C fifteen-sixteen artist (Primavera)" , "Famous Italian" , "who painted?" .)
