Diocletian and Maximian, in abdicating, secured themselves in the possession of considerable property and peculiar revenues. Maximian could not accustom himself to the tranquillity of private life and seized the first opportunity to resume the purple. Diocletian on the contrary returned to his own country, Dalmatia, and lived there until his death (313) as a private person at Salona. On his property in the vicinity of the present Spalatro, he occupied himself with gardening and with the erection of enormous buildings, the remains of which show us that architecture had entirely lost its noble character, and that attempts were made to supply the place of the taste of the olden times by elaboration and splendour.
Constantius Chlorus, whose health had long been failing, died a year after the abdication of Diocletian (306). Before his death he had earnestly commended his son Constantine to the army, and as soon as Constantius was dead it proclaimed his son emperor. Galerius was at first in great anxiety, but was satisfied when Constantine agreed to content himself with the title of Cæsar, granting Severus, as the elder man, the honours of an augustus or emperor. Constantine was the son of Helena, a woman of humble origin. Constantius had divorced her by command of the emperors Diocletian and Maximian in 292, in order to marry Theodora.
STRIFE AMONG THE RULERS
[306-307 A.D.]
In the autumn of the same year, the relations of the rulers of the empire again changed. Galerius and Severus, by their oppressive measures, had roused the anger of the citizens and soldiers of Rome. They rebelled and proclaimed Maxentius, the son of Maximian, emperor.
Zosimus declares that Maxentius incited the rebellion, moved thereto by jealousy of Constantine, a quite plausible supposition. “When Constantine’s effigy according to custom was exhibited at Rome,” he says, “Maxentius, the son of Maximian, could not endure the sight of Constantine’s good fortune, who was the son of a harlot, while himself, who was the son of so great an emperor, remained at home in indolence, and his father’s empire was enjoyed by others. He therefore associated with himself in the enterprise Marcellianus and Marcellus, two military tribunes, and Lucianus, who distributed the swine’s flesh with which the people of Rome were provided by the treasury, and the court-guards called prætoriani. By them he was promoted to the imperial throne, having promised liberally to reward all that assisted him in it. For this purpose they first murdered Abellius, because he, being prefect of the city, opposed their enterprise.
“When Galerius learned this,” Zosimus continues, “he sent Severus Cæsar against Maxentius with an army. But while he advanced from Milan with several legions of Moors, Maxentius corrupted his troops with money, and even the prefect of the court, Anullinus, and thereby conquered him with great ease. On which Severus fled to Ravenna, which is a strong and populous city, provided with necessaries sufficient for himself and soldiers. When Maximian[53] knew this, he was doubtless greatly concerned for his son Maxentius, and therefore, leaving Lucania where he then was, he went to Ravenna. Finding that Severus could not by any means be forced out of this city, it being well fortified and stored with provisions, he deluded him with false oaths, and persuaded him to go to Rome. But on his way thither, coming to a place called the Three Tabernæ, he was taken by a stratagem of Maxentius. [Hoping to save his life, he renounced the dignity of emperor; notwithstanding which he was] immediately executed. Galerius could not patiently endure these injuries done to Severus, and therefore resolved to go from the east to Rome, and to punish Maxentius as he deserved. On his arrival in Italy, he found the soldiers about him so treacherous, that he returned into the east without fighting a battle.”
On the retreat from Italy, after this unsuccessful foray, Galerius allowed his army to commit the most horrible outrages and thereby gained the deadly hatred of all the inhabitants of the peninsula. Meanwhile, Maximian had gone to Gaul to ally himself with Constantine against Galerius. He married his daughter Fausta to the young cæsar and invested him with the title of Augustus, but did not attain his special object, as Constantine did not consider it wise to allow himself to be drawn into open war with Galerius. Soon after this, Maximian quarrelled with his own son, again tried without success to win over Constantine, and then formed the strange resolve to betake himself to Galerius.
