Here is something interesting at the Discover Channel website: Lost Michelangelo Painting Found? A priest hears the confession of a former alter boy who romped around the church and discoverd a signature on the painting. He waited until he was in his 60s to confess. This prompted the priest to remove a part of the alter wall that then exposed the signature. This gave viable proof to Michelangelo as the painter. You gotta love kids running around the church!
