The Battle of Anghiari (Leonardo da Vinci)
In 1504 Leonardo da Vinci was given the commission by gonfaloniere Piero Soderini, a contract signed by Niccolò Machiavelli, to decorate the Hall of Five Hundred. At the same time his rival Michelangelo, who had just finished his "David", was designated the opposite wall. This was the only time that Leonardo da Vinci and Michelangelo worked together on the same project. The painting of Michelangelo depicted an episode from the Battle of Cascina, when a group of bathing soldiers was surprised by the enemy. However Michelangelo did not stay in Florence long enough to complete the project. He was able to finish his cartoon, but only began the painting. He was invited back to Rome in 1505 by the newly appointed Pope Julius II and was commissioned to build the Pope's tomb.
Sebastiano del Piombo
The last major work of the period was the "Raising of Lazarus", now in the National Gallery, London, which was commissioned in 1516 by Cardinal Giulio de Medici, archbishop of Narbonne in southern France, and the future Pope Clement VII, in blatant competition, engineered by Michelangelo, with a painting of the same size by Raphael, the "Transfiguration". Both were supposed to hang in Narbonne Cathedral. Michelangelo supplied at least drawings for the figure of Lazarus and the two men supporting him (British Museum), but probably did not do any work on the painting itself, if only because he was only briefly in Rome during the time it was painted. When the two paintings were hung together in the Vatican, just after Raphael's death in 1520, both were praised, but the Raphael generally preferred, as has remained the case ever since.
