lasted ninety-two years, from 193 to 284. During that time, thirty-two emperors, and twenty-seven pretenders to the empire, alternately hurried each other from the throne, by incessant civil warfare. Ninety-two years of almost incessant civil warfare taught the world _on what a frail foundation the virtue of the Antonines had reared the felicity of the empire_.” The full history of this period may be seen in Gibbon, i. pp. 50‒197. Of course it is impossible in these Notes to present anything like a complete account of the characteristics of those times. Yet the briefest summary may well show the general condition of the Roman empire then, and the propriety of representing it by the symbol of a red horse, as a period when peace would be taken from the earth, and when men would kill one another. Commodus himself is represented by Mr. Gibbon in the following words:――“Commodus was not, as he has been represented, a tiger, born with an insatiate thirst of human blood, and capable, from his infancy, of the most inhuman actions. Nature had formed him of a weak, rather than a wicked disposition. His simplicity and timidity rendered him the slave of his attendants, who gradually corrupted his mind. His cruelty, which at first obeyed the dictates of others, degenerated into habit, and at length became the ruling passion of his soul,” i. 51. During the first {148} three years of his reign “his hands were yet unstained with blood” (_Ibid._), but he soon degenerated into a most severe and bloody tyrant, and “when Commodus had once tasted human blood, he was incapable of pity or remorse,” i. 52. “The tyrant’s rage,” says Mr. Gibbon (i. 52), “after having shed the noblest blood of the senate, at length recoiled on the principal instrument of his cruelty. While Commodus _was immersed in blood and luxury_ he devolved the detail of public business on Perennis, a servile and ambitious minister, who had obtained his post by the murder of his predecessor,” &c. “Every sentiment of virtue and humanity was extinct in the mind of Commodus,” i. 55. After detailing the history of his crimes, his follies, and his cruelties, Mr. Gibbon remarks of him: “His cruelty proved at last fatal to himself. He had shed with impunity the best blood of Rome: he perished as soon as he was dreaded by his own domestics. Marcia, his favourite concubine, Eclectus, his chamberlain, and Lætus, his pretorian prefect, alarmed by the fate of their companions and predecessors, resolved to prevent the destruction which every hour hung over their heads, either from the mad caprice of the tyrant, or the sudden indignation of the people. Marcia seized the occasion of presenting a draught of wine to her lover, after he had fatigued himself with hunting some wild beasts. Commodus retired to sleep; but while he was labouring with the effects of poison and drunkenness, a robust youth, by profession a wrestler, entered his chamber, and strangled him without resistance,” i. 57.
