Alessandro di Mariano di Vanni Filipepi, better known as Sandro Botticelli c. 1445 – May 17, 1510), was an Italian painter of the Early Renaissance. He belonged to the Florentine School under the patronage of Lorenzo de' Medici, a movement that Giorgio Vasari would characterize less than a hundred years later as a "golden age", a thought, suitably enough, he expressed at the head of his Vita of Botticelli. Botticelli's posthumous reputation suffered until the late 19th century; since then his work has been seen to represent the linear grace of Early Renaissance painting. Among his best known works are The Birth of Venus and Primavera.
