It is a terrible shame. But the beauty of Michelangelo’s conception comes through in spite of it. The same goes for most of the Greek statues that have reached our times all broken and crushed. They are still beautiful!It seems that every fragment keeps the strange power of the whole. No earthquake, no vandalism, no damnatio temporis can harm the angel inside.
