Incomplete, Pietà Rondanini, 1564. Marble. Castello Sforzesco, Milan, Italy.
The bookman came across his archives of photographs which in 1994, he photographed Michelangelo Buonarroti’s last incomplete sculpture, the Pietà Rondanini at the Castello Sforzesco, Milan, Italy. This shows the desired which Michelangelo believed that one should never stop at what they are beholden to. Unlike the urge of sex which kept Pablo Picasso's desire for art going, but soon withered after his lost his virility.
Michelangelo could carve his sculpture from a single block of marble and he could alter the form as he visualized it in the process.
