San Pietro in Vincoli: Moses by Michelangelo (1989, 1995) My head goes to about his chest. He has horns because in those day the Bible was misinterrepted. They read Moses had 'horns' of light but it really says 'rays' of light. ANd this church also has a set of chains that supposedly were worn by St. Peter. Hence, the name of the church is really "St. Peter in chains."
