The negligence of the public administration was betrayed, soon afterwards, by a new disorder, which arose from the smallest beginnings. A spirit of desertion began to prevail among the troops: and the deserters, instead of seeking their safety in flight or concealment, infested the highways. Maternus, a private soldier, of a daring boldness above his station, collected these bands of robbers into a little army, set open the prisons, invited the slaves to assert their freedom, and plundered with impunity the rich and defenceless cities of Gaul and Spain. The governors of the provinces, who had long been the spectators, and perhaps the partners, of his depredations, were, at length, roused from their supine indolence by the threatening commands of the emperor. Maternus found that he was encompassed, and foresaw that he must be overpowered. A great effort of despair was his last resource. He ordered his followers to disperse, to pass the Alps in small parties and various disguises, and to assemble at Rome, during the licentious tumult of the festival of Cybele. 18 To murder Commodus, and to ascend the vacant throne, was the ambition of no vulgar robber. His measures were so ably concerted that his concealed troops already filled the streets of Rome. The envy of an accomplice discovered and ruined this singular enterprise, in a moment when it was ripe for execution. 19 18 (return) [ During the second Punic war, the Romans imported from Asia the worship of the mother of the gods. Her festival, the Megalesia, began on the fourth of April, and lasted six days. The streets were crowded with mad processions, the theatres with spectators, and the public tables with unbidden guests. Order and police were suspended, and pleasure was the only serious business of the city. See Ovid. de Fastis, l. iv. 189, &c.] 19 (return) [ Herodian, l. i. p. 23, 23.]
