By the time that Marius had got fairly established in his new position, and was completely master of Rome, and the city had begun to recover a little from the shock and consternation produced by his executions, he fell sick. He was attacked with an acute disease of great violence. The attack was perhaps produced, and was certainly aggravated by, the great mental excitements through which he had passed during his exile, and in the entire change of fortune which had attended his return. From being a wretched fugitive, hiding for his life among gloomy and desolate ruins, he found himself suddenly transferred to the mastery of the world. His mind was excited, too, in respect to Sylla, whom he had not yet reached or subdued, but who was still prosecuting his war against Mithridates. Marius had had him pronounced by the Senate an enemy to his country, and was meditating plans to reach him in his distant province, considering his triumph incomplete as long as his great rival was at liberty and alive. The sickness cut short these plans, but it only inflamed to double violence the excitement and the agitations which attended them. [Sidenote: Marius delirious.] [Sidenote: Death of Marius.] As the dying tyrant tossed restlessly upon his bed, it was plain that the delirious ravings which he began soon to utter were excited by the same sentiments of insatiable ambition and ferocious hate whose calmer dictates he had obeyed when well. He imagined that he had succeeded in supplanting Sylla in his command, and that he was himself in Asia at the head of his armies. Impressed with this idea, he stared wildly around; he called aloud the name of Mithridates; he shouted orders to imaginary troops; he struggled to break away from the restraints which the attendants about his bedside imposed, to attack the phantom foes which haunted him in his dreams. This continued for several days, and when at last nature was exhausted by the violence of these paroxysms of phrensy, the vital powers which had been for seventy long years spending their strength in deeds of selfishness, cruelty, and hatred, found their work done, and sunk to revive no more.
