Michelangelo
With the completion of the "David" came another commission. In early 1504 Leonardo da Vinci had been commissioned to paint "The Battle of Anghiara" in the council chamber of the Palazzo Vecchio, depicting the battle between Florence and Milan in 1440. Michelangelo was then commissioned to paint the "Battle of Cascina". The two paintings are very different: Leonardo depicts soldiers fighting on horseback, while Michelangelo has soldiers being ambushed as they bathe in the river. Neither work was completed and both were lost forever when the chamber was refurbished. Both works were much admired, and copies remain of them, Leonardo's work having been copied by Rubens and Michelangelo's by Bastiano da Sangallo.
Medici Chapel
Though it was vaulted over by 1524, the ambitious projects of its sculpture and the intervention of events, such as the temporary exile of the Medici (1527), the death of Giulio, now Pope Clement VII and the permanent departure of Michelangelo for Rome in 1534, meant that Michelangelo never finished it. Though most of the statues had been carved by the time of Michelangelo's departure, they had not been put in place, being left in disarray across the chapel, and later installed by Niccolò Tribolo in 1545. By order of Cosimo I, Giorgio Vasari and Bartolomeo Ammannati finished the work by 1555.
