Angels and Apollo
The round papal fortress of Castel Sant 'Angelo, seen in the film "Angels and Demons" has a connection to a Roman Emperor and a pagan sun god. It was built as a mausoleum for himself and his family by Emperor Hadrian. A bronze statue of Hadrian as Apollo driving the sun chariot topped the tomb in Hadrian's time. A pope replaced it with a bronze statue of the Archangel Michael.
