The measures of the conspirators were conducted with the deliberate coolness and celerity which the greatness of the occasion required. They resolved instantly to fill the vacant throne with an emperor whose character would justify and maintain the action that had been committed. They fixed on Pertinax, præfect of the city, an ancient senator of consular rank, whose conspicuous merit had broke through the obscurity of his birth, and raised him to the first honors of the state. He had successively governed most of the provinces of the empire; and in all his great employments, military as well as civil, he had uniformly distinguished himself by the firmness, the prudence, and the integrity of his conduct. He now remained almost alone of the friends and ministers of Marcus; and when, at a late hour of the night, he was awakened with the news, that the chamberlain and the præfect were at his door, he received them with intrepid resignation, and desired they would execute their master’s orders. Instead of death, they offered him the throne of the Roman world. During some moments he distrusted their intentions and assurances. Convinced at length of the death of Commodus, he accepted the purple with a sincere reluctance, the natural effect of his knowledge both of the duties and of the dangers of the supreme rank. Lætus conducted without delay his new emperor to the camp of the Prætorians, diffusing at the same time through the city a seasonable report that Commodus died suddenly of an apoplexy; and that the virtuous Pertinax had already succeeded to the throne. The guards were rather surprised than pleased with the suspicious death of a prince, whose indulgence and liberality they alone had experienced; but the emergency of the occasion, the authority of their præfect, the reputation of Pertinax, and the clamors of the people, obliged them to stifle their secret discontents, to accept the donative promised by the new emperor, to swear allegiance to him, and with joyful acclamations and laurels in their hands to conduct him to the senate house, that the military consent might be ratified by the civil authority.
