As a supplement to the reign of Marcus Aurelius, we ought to notice the rise of one great rebel, the sole civil disturber of his time, in Syria. This was Avidius Cassius, whose descent from Cassius (the noted conspirator against the great Dictator, Julius) seems to have suggested to him a wandering idea, and at length a formal purpose of restoring the ancient republic. Avidius was the commander-in-chief of the Oriental army, whose head-quarters were then fixed at Antioch. His native disposition, which inclined him to cruelty, and his political views, made him, from his first entrance upon office, a severe disciplinarian. The well known enormities of the neighboring Daphne gave him ample opportunities for the exercise of his harsh propensities in reforming the dissolute soldiery. He amputated heads, arms, feet, and hams: he turned out his mutilated victims, as walking spectacles of warning; he burned them; he smoked them to death; and, in one instance, he crucified a detachment of his army, together with their centurions, for having, unauthorized, gained a splendid victory, and captured a large booty on the Danube. Upon this the soldiers mutinied against him, in mere indignation at his tyranny. However, he prosecuted his purpose, and prevailed, by his bold contempt of the danger which menaced him. From the abuses in the army, he proceeded to attack the abuses of the civil administration. But as these were protected by the example of the great proconsular lieutenants and provincial governors, policy obliged him to confine himself to verbal expressions of anger; until at length, sensible that this impotent railing did but expose him to contempt, he resolved to arm himself with the powers of radical reform, by open rebellion. His ultimate purpose was the restoration of the ancient republic, or, (as he himself expresses it in an interesting letter, which yet survives,) "_ut in antiquum statum publica forma reddatur_;" _i.e._ that the constitution should be restored to its original condition. And this must be effected by military violence and the aid of the executioner--or, in his own words, _multis gladiis, multis elogiis_, (by innumerable sabres, by innumerable records of condemnation.) Against this man Marcus was warned by his imperial colleague Lucius Verus, in a very remarkable letter. After expressing his suspicions of him generally, the writer goes on to say--"I would you had him closely watched. For he is a general disliker of us and of our doings; he is gathering together an enormous treasure, and he makes an open jest of our literary pursuits. You, for instance, he calls a philosophizing old woman, and me a dissolute buffoon and scamp. Consider what you would have done. For my part, I bear the fellow no ill will; but again, I say, take care that he does not do a mischief to yourself, or your children."
