FLORENCE, ITALY—Millions flocked to a museum in Florence this week to witness an image of Christ's face suspended on an ordinary piece of canvas. "It is Him!" said Paolo Bruni, 63, a merchant from Sorrento who traveled 200 miles to the diSforzi Museum to see the vision of Christ floating in the middle of a "golden rectangle." "It is truly a miracle," he said. Despite the clear depiction of Christ, many remain unconvinced. "It is a trick of the light," said German tourist Dieter Ühler, 34. "This is, ah, how do you say, an impossibility." The discovery of the miracle canvas comes just weeks after the supposed discovery of a 9x12-inch piece of paper with some fruit on it in a French museum.
