St. George
Soldier Martyr, Roman general and convert to Christianity. Exposed as a Christian, but the military tribunal decided he was a good soldier who had made a mistake, told him to reconsider. He was set free but promptly burned down a pagan temple. He is represented riding a horse and killing a snake-like dragon (symbol of cosmic evil) with his spear.
