Michelangelo's famous Moses sculpture at San Pietro in Vincoli (St. Peter in chains), inspiration for weirdos as diverse as Sigmund Freud and Cecil B. DeMille (who cast Charlton Heston as Moses in The Ten Commandments simply due to the actor's physical resemblance to the statue--yes, I see the joke in that statement). The church also houses what are purported to be the actual chains with which St. Peter was imprisoned. The chains were originally housed in two separate locations, and when brought together in their current location miraculously snapped together to form one unbroken chain. Careful observers might see in this story a metaphor about the "unbroken chain" of papal succession dating all the way back to St. Peter, and by extension, Jesus.
