Happy Birthday Sandro Botticelli!! Italian painter from 1444, Botticelli was born in Florence. He worked closely with Filippino Lippi and was a pupil of Lippi's father. There is some confusion as to which paintings belong to whom in some cases since they worked quite similarly. Although he was commissioned to create frescoes for the Sistine Chapel, his best work is the tempera on panel, such as The Birth of Venus and the Mystic Nativity included here. He never did reach the status of contemporaries Raphael, da Vinci or Michelangelo.
