Sandro Botticelli

I think the Venus painting Botticello did was his most famous one. It's interesting because in my ISMs book, they talk about Botticello in the secularism book, hence the Venus painting (pagan and mythological), but about.com is talking about his somewhat drastically religious at one point and destroyed some of his paintings (I'm guessing the more secular ones).

He's from the Florentine school of early Italian Rennaissance and is considered to be somewhat overshadowed by some the the more influencial artists from that time.

I read that his work is sort of old fashioned compared to some of the artists of his time. He has some paintings in the Sistine Chapel and was a patronized by members of the Medici family.
