The saltcellar stolen from the Kunsthistorisches Museum in Vienna over the weekend was crafted by the great Renaissance sculptor and metalworker Benvenuto Cellini in the 1540s. It was called by some the “Mona Lisa” of sculpture to give a sense of its importance, and is said to be worth $57 million. “It was extremely fragile. It wasn’t cast in solid gold, but hammered into its delicate shape. I think if it comes back it will reappear all in pieces or as a ruin. The whole thing happened in less than one minute; in such a hurry [I can’t imagine] that a piece of this fragility could survive.”
