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)
Donatello's bronze statue of David (circa 1440s) is famous as the first unsupported standing work of bronze cast during the Renaissance, and the first freestanding nude male sculpture made since antiquity. It depicts David with an enigmatic smile, posed with his foot on Goliath's severed head just after defeating the giant. The youth is completely naked, apart from a laurel-topped hat and boots, and bears the sword of Goliath.
The creation of the work is entirely undocumented, and it has been given a range of datings. According to one theory, it was commissioned by the Medici family in the 1430s to be placed in the centre of the courtyard of the old Medici Palace. Alternatively it may have been for that position in the new Palazzo Medici Riccardi, where it certainly was placed later, which would place the commission in the mid-1440s or even later. The statue is recorded there by Vasari and other sources. The Medici family were exiled from Florence in 1494, and the statue was moved to the courtyard of the Palazzo della Signoria (the marble "David" was already in the palazzo). It was moved to the Palazzo Pitti in the 17th century, to the Uffizi in 1777, and then finally, in 1865, to the Museo Nazionale del Bargello, where it remains today.
