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. 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. 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. 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; 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, and the public tranquillity was confirmed by the execution of the surviving leaders of a guilty and unsuccessful faction. A severe inquisition was extended over all who, either from choice or from compulsion, had been involved in the cause of rebellion. Paul, surnamed Catena from his superior skill in the judicial exercise of tyranny, * was sent to explore the latent remains of the conspiracy in the remote province of Britain. The honest indignation expressed by Martin, vice-præfect of the island, was interpreted as an evidence of his own guilt; and the governor was urged to the necessity of turning against his breast the sword with which he had been provoked to wound the Imperial minister. The most innocent subjects of the West were exposed to exile and confiscation, to death and torture; and as the timid are always cruel, the mind of Constantius was inaccessible to mercy.
