Theogeny out the window

One of my favorite topics is Mythology. I hardly take the time to ever think about the transition from Pagan beliefs to Christianity. So after reading this section it's kind of wierd to see religious leaders trying to claim power in Rome. When I hear about Leo I claiming that Peter was chief of all apostles making the bishop of Rome the head of all bishops, its crazy to think that those claims weren't even considered before the fall of the Roman Empire. In Virgils Aenied, Aeneis' line is supposed to end with the founding of Rome, Romulus is supposedly the actual founder of Rome. I couldn't imagine having my beliefs at one period in my life, then rewriting the histories to make room for a whole other set of beliefs. Going from (for Romans)Jupiter(zeus) to God.
