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.
Leda and the Swan
Also lost, and probably deliberately destroyed, is Michelangelo's tempera painting of the pair making love, commissioned in 1529 by Alfonso d'Este for his palazzo in Ferrara, and taken to France for the royal collection in 1532; it was at Fontainebleau in 1536. Michelangelo's cartoon for the work—given to his assistant Antonio Mini, who used it for several copies for French patrons before his death in 1533—survived for over a century. This composition is known from many copies, including an by Cornelis Bos, c. 1563; the marble sculpture by Bartolomeo Ammanati in the Bargello, Florence; two copies by the young Rubens on his Italian voyage, and the painting after Michelangelo, ca. 1530, in the National Gallery, London. The Michelangelo composition, of about 1530, shows Mannerist tendencies of elongation and twisted pose (the "figura serpentinata") that were popular at the time. In addition, a sculptural group, similar to the Prado Roman group illustrated, was believed until at least the 19th century to be by Michelangelo.
