Pertĭnax Publius Helvius, a Roman emperor after the death of Commodus. He was descended from an obscure family, and, like his father, who was either a slave or the son of a manumitted slave, he for some time followed the mean employment of drying wood and making charcoal. His indigence, however, did not prevent him from receiving a liberal education, and indeed he was for some time employed in teaching a number of pupils the Greek and the Roman languages in Etruria. He left this laborious profession for a military life, and by his valour and intrepidity, he gradually rose to offices of the highest trust in the army, and was made consul by Marcus Aurelius for his eminent services. He was afterwards entrusted with the government of Mœsia, and at last he presided over the city of Rome as governor. When Commodus was murdered, Pertinax was universally selected to succeed to the imperial throne, and his refusal, and the plea of old age and increasing infirmities, did not prevent his being saluted emperor and Augustus. He acquiesced with reluctance, but his mildness, his economy, and the popularity of his administration, convinced the senate and the people of the prudence and the justice of their choice. He forbade his name to be inscribed on such places or estates as were part of the imperial domain, and exclaimed that they belonged not to him, but to the public. He melted all the silver statues which had been raised to his vicious predecessor, and he exposed to public sale all his concubines, his horses, his arms, and all the instruments of his pleasure and extravagance. With the money raised from these he enriched the empire, and was enabled to abolish all the taxes which Commodus had laid on the rivers, ports, and highways through the empire. This patriotic administration gained him the affection of the worthiest and most discerning of his subjects, but the extravagant and luxurious raised their clamours against him, and when Pertinax attempted to introduce among the pretorian guards that discipline which was so necessary to preserve the peace and tranquillity of Rome, the flames of rebellion were kindled, and the minds of the soldiers totally alienated. Pertinax was apprised of this mutiny, but he refused to fly at the hour of danger. He scorned the advice of his friends who wished him to withdraw from the impending storm, and he unexpectedly appeared before the seditious pretorians, and without fear or concern, boldly asked them whether they, who were bound to defend the person of their prince and emperor, were come to betray him and to shed his blood. His undaunted assurance and his intrepidity would have had the desired effect, and the soldiers had already begun to retire, when one of the most seditious advanced and darted his javelin at the emperor’s breast, exclaiming, “The soldiers send you this.” The rest immediately followed the example, and Pertinax, muffling up his head, and calling upon Jupiter to avenge his death, remained unmoved, and was instantly dispatched. His head was cut off, and carried upon the point of a spear as in triumph to the camp. This happened on the 28th of March, A.D. 193. Pertinax reigned only 87 days, and his death was the more universally lamented, as it proceeded from a seditious tumult, and robbed the Roman empire of a wise, virtuous, and benevolent emperor.
