There was a problem to be solved in the minds of some art historians. Despite these interesting findings, there was a scene missing from the story of Saint Peter. It is the scene where Jesus says "You are Peter, and on this Rock I build my Church." This part of the story is of the greatest importance to the Roman Catholic Church because Peter was the first Bishop of Rome, and so the Pope rules as his direct line. The scene is usually shown by Jesus giving Peter the "Keys of Heaven". "The Keys", for hundreds of years, have been the symbol of the Pope. But the story of "the Keys" is completely missing.
