The dragon legend

One explanation of the dragon legend involves a large crocodile with wings. Basically the dragon would eat anyone who spent too long outside the city walls. A couple of sheep were sacrificed everyday to keep the monster satisfied. When there were no more sheep, they started on the children. But when it was time for the king's daughter to become the sacrifice, St. George steps in, does battle with the dragon and goes down in history.

It's quite plausible of course that George killed a crocodile, and the story got a little exagerated and spun out. Read the whole story and make your own mind up.
