The Cornaro Chapel at the Santa Maria della Vittoria church in Rome sports many beautiful works of art, but I'm especially taken by the skeletal figure set into the floor tiles, whose upraised arms seem ready to snatch sinners into the underworld. The photo above was taken by Chris and memorialized in a fabulous post on Roman Patina, which also includes photos of many of the other works in the chapel.
