Whilst Constantine contented himself with establishing his power in the three western provinces, Galerius undertook to avenge the death of Severus on Maxentius. He therefore came with an army to Italy, and advanced as far as Narni; but there he found himself so closely hemmed in by the forces of old Maximian, and so little supported, that he had to retreat and make peace. How it was concluded, we have in truth no account whatever. After the death of Severus, Galerius had given up Illyricum to Licinius, and had bestowed on him at the same time the title of Augustus; the east he had assigned to Maximinus Daza: he acknowledged Constantine as Augustus. Thus the Roman world had no more Cæsars, but six _Augusti_,—Galerius, Licinius, Maximin in the east; Maximian, Maxentius, and Constantine in the west. Notwithstanding this, there was no peace, and the artificial combination of Diocletian proved insufficient. Maximian had given his daughter Fausta in marriage to Constantine, who therefore divorced himself from his first wife Minervina. But dissensions arose between Maximian and his son Maxentius. Maxentius, who was a fell tyrant in the style of Caracalla, had no dutiful feelings towards a father who had raised him to the throne; and he answered the claims of his father to rule the state, by the counter demand that he should retire from public affairs. The prætorians, whom Maxentius had brought out again from the obscurity into which Diocletian had thrown them, decided that Maxentius should reign alone. Maximian now went to his daughter in Gaul, where at first he met with a friendly reception; but he soon got embroiled with Constantine. When the latter tried to secure himself against him, Maximian, who was not able to stand his ground at Arles, fled to Marseilles, where he was besieged, and delivered up as a victim by his own troops. He fell into Constantine’s power, who made him kind promises; notwithstanding which, under the pretext of his having set on foot a conspiracy, he was soon afterwards put to death.
