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.
The Creation of Adam
Under the patronage of the Pope, Michelangelo experienced constant interruptions to his work on the tomb in order to accomplish numerous other tasks. Although Michelangelo worked on the tomb for 40 years, it was never finished to his satisfaction. It is located in the Church of S. Pietro in Vincoli in Rome and is most famous for his central figure of "Moses", completed in 1516. Of the other statues intended for the tomb, two known as the "Rebellious Slave" and the "Dying Slave", are now in the Louvre.
