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.
Taddei Tondo
The tondo dates to Michelangelo's time in Florence before his move to Rome in 1505. According to Vasari, while working on his David, "also at this time he blocked out but did not finish two marble tondi, one for Taddeo Taddei, today in his house, and for Bartolomeo Pitti he began another... which works were considered outstanding and marvellous".
