Eutropia's confession about the father of Maxentius
Meanwhile Constantine after defeating the tyrant's generals at verona, went on to Rome. When he had reached the city, Maxentius came out and chose a plain above the Tiber as the place to do battle. There the usurper was defeated, and when all his men were put to flight, he was prevented from escaping by the crowd of fugitives, thrown from his horse into the river, and drowned. On the following day his body was recovered from the river, and the head was cut off and taken into Rome. When his mother was questioned about his parentage, she admitted that he was the son of a Syrian. He ruled for six years.
