receive or to oppose them. Provoked by such treatment, which they considered as trifling and perfidious, the Alani had recourse to their own valor for their payment and revenge; and as they moved with the usual swiftness of Tartars, they had soon spread themselves over the provinces of Pontus, Cappadocia, Cilicia, and Galatia. The legions, who from the opposite shores of the Bosphorus could almost distinguish the flames of the cities and villages, impatiently urged their general to lead them against the invaders. The conduct of Tacitus was suitable to his age and station. He convinced the barbarians of the faith, as well as the power, of the empire. Great numbers of the Alani, appeased by the punctual discharge of the engagements which Aurelian had contracted with them, relinquished their booty and captives, and quietly retreated to their own deserts, beyond the Phasis. Against the remainder, who refused peace, the Roman emperor waged, in person, a successful war. Seconded by an army of brave and experienced veterans, in a few weeks he delivered the provinces of Asia from the terror of the Scythian invasion.

But the glory and life of Tacitus were of short duration. Transported, in the depth of winter, from the soft retirement of Campania to the foot of Mount Caucasus, he sunk under the unaccustomed hardships of a military life. The fatigues of the body were aggravated by the cares of the mind. For a while, the angry and selfish passions of the soldiers had been suspended by the enthusiasm of public virtue. They soon broke out with redoubled violence, and raged in the camp, and even in the tent of the aged emperor. His mild and amiable character served only to inspire contempt, and he was incessantly tormented with factions which he could not assuage, and by demands which it was impossible to satisfy. Whatever flattering expectations he had conceived of reconciling the public disorders, Tacitus soon was convinced that the licentiousness of the army disdained the feeble restraint of laws, and his last hour was hastened by anguish and disappointment. It may be doubtful whether the soldiers imbrued their hands in the blood of this innocent prince. It is certain that their insolences was the cause of his death. He expired at Tyana in Cappadocia, after a reign of only six months and about twenty days.

The eyes of Tacitus were scarcely closed, before his brother Florianus showed himself unworthy to reign, by the hasty usurpation of the purple, without expecting the approbation of the senate. The reverence for the Roman constitution, which yet influenced the camp and the provinces, was sufficiently strong to dispose them to censure, but not to provoke them to oppose, the precipitate ambition of Florianus. The discontent would have evaporated in idle murmurs, had not the general of the East, the heroic Probus, boldly declared himself the avenger of the senate. The contest, however, was still unequal; nor could the most able leader, at the head of the effeminate troops of Egypt and Syria, encounter, with any hopes of victory, the legions of Europe, whose irresistible strength appeared to support the brother of Tacitus. But the fortune and activity of Probus triumphed over every obstacle. The hardy veterans of his rival, accustomed to cold climates, sickened and consumed away in the sultry heats of Cilicia, where the summer proved remarkably unwholesome. Their numbers were diminished by frequent desertion; the passes of the mountains were feebly defended; Tarsus opened its gates; and the soldiers of Florianus, when they had permitted him to enjoy the Imperial title about three months, delivered the empire from civil war by the easy sacrifice of a prince whom they despised.

The perpetual revolutions of the throne had so perfectly erased every notion of hereditary title, that the family of an unfortunate emperor was incapable of exciting the jealousy of his successors. The children of Tacitus and Florianus were permitted to descend into a private station, and to mingle with the general mass of the people. Their poverty indeed became an additional safeguard to their innocence. When Tacitus was elected by the senate, he resigned his ample patrimony to the public service; an act of generosity specious in appearance, but which evidently disclosed his intention of transmitting the empire to his descendants. The only consolation of their fallen state was the remembrance of transient greatness, and a distant hope, the child of a flattering prophecy, that at the end of a thousand years, a monarch of the race of Tacitus should arise, the protector of the senate, the restorer of Rome, and the conqueror of the whole earth.

The peasants of Illyricum, who had already given Claudius and Aurelian to the sinking empire, had an equal right to glory in the elevation of Probus. Above twenty years before, the emperor Valerian, with his usual penetration, had discovered the rising merit of the young soldier, on whom he conferred the
