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.
Michelangelo
Michelangelo, with Leonardo da Vinci and Raphael, is one of the three giants of the Florentine High Renaissance. Although their names are often cited together, Michelangelo was younger than Leonardo by 23 years, and older than Raphael by eight. Because of his reclusive nature, he had little to do with either artist and outlived both of them by more than forty years. Michelangelo took few sculpture students. He employed Francesco Granacci, who was his fellow pupil at the Medici Academy, and became one of several assistants on the Sistine Chapel ceiling. Michelangelo appears to have used assistants mainly for the more manual tasks of preparing surfaces and grinding colours. Despite this, his works were to have a great influence on painters, sculptors and architects for many generations to come.
