Wool merchant Agnolo di Francesco Doni died on 5 January 1539 in Florence. He was 65. Agnolo used some of his fortune to commission and collect works of art by leading Renaissance artists including Raphael, Michelangelo, Fra Bartolommeo, and Donatello. In 1504, Doni commissioned portraits of himself and his new bride Maddalena di Giovanni Strozzi from Raphael and soon thereafter hired Michelangelo to paint a round image, or tondo, showing the Holy Family enclosed in an elaborately carved frame.
