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.
Galleria dell'Accademia
The Galleria dell'Accademia has housed the original "David" by Michelangelo since 1873. The sculpture was allegedly brought to the Accademia for reasons of conservation, although other factors were involved in its move from its previous outdoor location on Piazza della Signoria. The original intention was to create a 'Michelangelo museum', with original sculptures and drawings, to celebrate the fourth centenary of the artist's birth. Today, the gallery's small collection of Michelangelo's work includes his four unfinished "Prisoners", intended for the tomb of Pope Julius II, and a statue of Saint Matthew, also unfinished. In 1939, these were joined by a "Pietà" discovered in the Barberini chapel in Palestrina, though experts now consider its attribution to Michelangelo to be dubious.
