The pride of Magnentius was reduced, by repeated misfortunes, to sue, and to sue in vain, for peace. He first despatched a senator, in whose abilities he confided, and afterwards several bishops, whose holy character might obtain a more favorable audience, with the offer of resigning the purple, and the promise of devoting the remainder of his life to the service of the emperor. But Constantius, though he granted fair terms of pardon and reconciliation to all who abandoned the standard of rebellion, 92 avowed his inflexible resolution to inflict a just punishment on the crimes of an assassin, whom he prepared to overwhelm on every side by the effort of his victorious arms. An Imperial fleet acquired the easy possession of Africa and Spain, confirmed the wavering faith of the Moorish nations, and landed a considerable force, which passed the Pyrenees, and advanced towards Lyons, the last and fatal station of Magnentius. 93 The temper of the tyrant, which was never inclined to clemency, was urged by distress to exercise every act of oppression which could extort an immediate supply from the cities of Gaul. 94 Their patience was at length exhausted; and Treves, the seat of Prætorian government, gave the signal of revolt, by shutting her gates against Decentius, who had been raised by his brother to the rank either of Cæsar or of Augustus. 95 From Treves, Decentius was obliged to retire to Sens, where he was soon surrounded by an army of Germans, whom the pernicious arts of Constantius had introduced into the civil dissensions of Rome. 96 In the mean time, the Imperial troops forced the passages of the Cottian Alps, and in the bloody combat of Mount Seleucus irrevocably fixed the title of rebels on the party of Magnentius. 97 He was unable to bring another army into the field; the fidelity of his guards was corrupted; and when he appeared in public to animate them by his exhortations, he was saluted with a unanimous shout of “Long live the emperor Constantius!” The tyrant, who perceived that they were preparing to deserve pardon and rewards by the sacrifice of the most obnoxious criminal, prevented their design by falling on his sword; 98 a death more easy and more honorable than he could hope to obtain from the hands of an enemy, whose revenge would have been colored with the specious pretence of justice and fraternal piety. The example of suicide was imitated by Decentius, who strangled himself on the news of his brother’s death. The author of the conspiracy, Marcellinus, had long since disappeared in the battle of Mursa, 99 and the public tranquillity was confirmed by the execution of the surviving leaders of a guilty and unsuccessful faction.
