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.
Pietà (Michelangelo)
Sculpting of the work took less than two years. Following completion, the "Pietà"'s first home was the Chapel of Santa Petronilla, a Roman mausoleum near the south transept of St. Peter's, which the Cardinal chose as his funerary chapel. The chapel was later demolished by Bramante during his rebuilding of the basilica. According to Giorgio Vasari, shortly after the installation of his "Pietà", Michelangelo overheard (or asked visitors about the sculptor) someone remark that it was the work of another sculptor, Cristoforo Solari, whereupon Michelangelo signed the sculpture. Michelangelo carved (Michelangelo Buonarroti, Florentine, made this) on the sash running across Mary's chest. The signature echoes one used by the ancient Greek artists, Apelles and Polykleitos. It was the only work he ever signed. Vasari also reports the anecdote that Michelangelo later regretted his outburst of pride and swore never to sign another work of his hands.
