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.
Head of a Faun
Head of a faun is a lost sculpture by Italian Renaissance master Michelangelo, dating from c. 1489. His first known work of sculpture in marble, it was sculpted when he was 15 or 16 as a copy of an antique work with some minor alterations. According to Giorgio Vasari's biography of the artist, it was the creation of this work that secured the young Michaelangelo the patronage of Lorenzo de' Medici.
