Such, amidst the sacred security and inviolability of the office, was the hazardous tenure of the individual. Nor did his dangers always arise from persons in the rank of competitors and rivals. Sometimes it menaced him in quarters which his eye had never penetrated, and from enemies too obscure to have reached his ear. By way of illustration we will cite a case from the life of the Emperor Commodus, which is wild enough to have furnished the plot of a romance--though as well authenticated as any other passage in that reign. The story is narrated by Herodian, and the circumstances are these: A slave of noble qualities, and of magnificent person, having liberated himself from the degradations of bondage, determined to avenge his own wrongs by inflicting continual terror upon the town and neighborhood which had witnessed his humiliation. For this purpose he resorted to the woody recesses of the province, (somewhere in the modern Transylvania,) and, attracting to his wild encampment as many fugitives as he could, by degrees he succeeded in forming and training a very formidable troop of freebooters. Partly from the energy of his own nature, and partly from the neglect and remissness of the provincial magistrates, the robber captain rose from less to more, until he had formed a little army, equal to the task of assaulting fortified cities. In this stage of his adventures, he encountered and defeated several of the imperial officers commanding large detachments of troops; and at length grew of consequence sufficient to draw upon himself the emperor's eye, and the honor of his personal displeasure. In high wrath and disdain at the insults offered to his eagles by this fugitive slave, Commodus fulminated against him such an edict as left him no hope of much longer escaping with impunity. Public vengeance was now awakened; the imperial troops were marching from every quarter upon the same centre; and the slave became sensible that in a very short space of time he must be surrounded and destroyed. In this desperate situation he took a desperate resolution: he assembled his troops, laid before them his plan, concerted the various steps for carrying it into effect, and then dismissed them as independent wanderers. So ends the first chapter of the tale.
