The Florentine painter Botticelli produced some of the most celebrated pictures of the Renaissance. His Primavera ('Spring') and Birth of Venus (both in the Uffizi, Florence) were painted for members of the powerful Medici family. He trained as a goldsmith before joining Filippo Lippi's workshop. The ideal beauty of his graceful madonnas and mythological figures emphasises expressive and sensuous forms rather than anatomical accuracy. He left Florence briefly (1481-2) to work on frescoes in the Sistine Chapel, Rome. His later paintings, are infused with an expressive intensity, influenced by the stern preaching of Savonarola.
