" He was forty years old, and for six years he had been struggling to claim the crown of the imperator. Less than twenty-four hours before, he had finally beaten the sitting emperor of Rome, twenty-nine-year-old Maxentius, at the Battle of the Milvian Bridge. Constantine’s men had fought their way forward across the bridge, toward the city of Rome, until the defenders broke and ran. Maxentius drowned, pulled down into the mud of the riverbed by the weight of his armor. The Christian historian Lactantius tells us that Constantine’s men marched into Rome with the sign of Christ marked on each shield; the Roman* writer Zosimus adds that they also carried Maxentius’s waterlogged head on the tip of a spear. Constantine had dredged the body up and decapitated it.1 "
