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.
Transfiguration (Raphael)
From 11 to 12 December 1516, Michelangelo was in Rome to discuss with Pope Leo X and Cardinal Medici the facade of the Basilica of San Lorenzo in Florence. During this meeting, he was confronted with the commission of "The Raising of Lazarus" and it was here that he agreed to provide drawings for the endeavour, but not to execute the painting himself. The commission went to Michelangelo's friend Sebastiano del Piombo. As of this meeting the paintings would become emblematic of a paragone between two approaches to painting, and between painting and sculpture in Italian art.
