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.
Apollo (Michelangelo)
Hallmarks of his style and methods exist on the unfinished work that support the attribution of the statue to Michelangelo. The subject of the unfinished statue was never noted by Michelangelo, however, and contemporary historical sources disagree about the subject. According to Vasari it is an "Apollo", perhaps in the act of taking an arrow from a quiver. In the inventory of Cosimo I of 1553, however, it is identified as, "David", by whoever drew up the historic catalogue. Art critics therefore identify the sculpture as one or the other, or, by showing a hyphenated title, "Apollo-David" or "David-Apollo", to note the uncertainty. Factors favoring the identity as Apollo are: the body is stocky and mature, as Apollo often was portrayed, rather than the typical portrayal of a youthful David; no bow is represented in the carving and, no unfinished portion of the statue allows enough area for one.
