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.
David (Donatello)
David is the title of two statues of the biblical hero David by the Italian early Renaissance sculptor Donatello. They consist of an early work in marble of a clothed figure (1408–09), and a far more famous bronze figure that is nude between its helmet and boots, and dates to the 1440s or later. Both are now in the Museo Nazionale del Bargello in Florence.
