The David is considered a masterpiece, an ideal male form combining heroic strength and human uncertainty. It is erected in 1504 in the public plaza of Florence, the Piazza della Signoria.
When he created his David, Michelangelo was not even thirty, but had already produced works of great value such as the Tondo Doni which can be found in the Uffizi today. His David was so successful that he was called back to Rome by the Pope himself, Giulio II, for whom he would then paint the famous Sistine Chapel.
