called upon him to take up arms, he readily exposed his person to eight winter campaigns, on the frozen banks of the Danube, the severity of which was at last fatal to the weakness of his constitution. His memory was revered by a grateful posterity, and above a century after his death, many persons preserved the image of Marcus Antoninus among those of their household gods.

If a man were called to fix the period in the history of the world, during which the condition of the human race was most happy and prosperous, he would, without hesitation, name that which elapsed from the death of Domitian to the accession of Commodus. The vast extent of the Roman empire was governed by absolute power, under the guidance of virtue and wisdom. The armies were restrained by the firm but gentle hand of four successive emperors, whose characters and authority commanded involuntary respect. The forms of the civil administration were carefully preserved by Nerva, Trajan, Hadrian, and the Antonines, who delighted in the image of liberty, and were pleased with considering themselves as the accountable ministers of the laws. Such princes deserved the honor of restoring the republic, had the Romans of their days been capable of enjoying a rational freedom.

The labors of these monarchs were overpaid by the immense reward that inseparably waited on their success; by the honest pride of virtue, and by the exquisite delight of beholding the general happiness of which they were the authors. A just but melancholy reflection imbittered, however, the noblest of human enjoyments. They must often have recollected the instability of a happiness which depended on the character of single man. The fatal moment was perhaps approaching, when some licentious youth, or some jealous tyrant, would abuse, to the destruction, that absolute power, which they had exerted for the benefit of their people. The ideal restraints of the senate and the laws might serve to display the virtues, but could never correct the vices, of the emperor. The military force was a blind and irresistible instrument of oppression; and the corruption of Roman manners would always supply flatterers eager to applaud, and ministers prepared to serve, the fear or the avarice, the lust or the cruelty, of their master.

These gloomy apprehensions had been already justified by the experience of the Romans. The annals of the emperors exhibit a strong and various picture of human nature, which we should vainly seek among the mixed and doubtful characters of modern history. In the conduct of those monarchs we may trace the utmost lines of vice and virtue; the most exalted perfection, and the meanest degeneracy of our own species. The golden age of Trajan and the Antonines had been preceded by an age of iron. It is almost superfluous to enumerate the unworthy successors of Augustus. Their unparalleled vices, and the splendid theatre on which they were acted, have saved them from oblivion. The dark, unrelenting Tiberius, the furious Caligula, the feeble Claudius, the profligate and cruel Nero, the beastly Vitellius, and the timid, inhuman Domitian, are condemned to everlasting infamy. During fourscore years (excepting only the short and doubtful respite of Vespasian's reign) Rome groaned beneath an unremitting tyranny, which exterminated the ancient families of the republic, and was fatal to almost every virtue and every talent that arose in that unhappy period.

Under the reign of these monsters, the slavery of the Romans was accompanied with two peculiar circumstances, the one occasioned by their former liberty, the other by their extensive conquests, which rendered their condition more completely wretched than that of the victims of tyranny in any other age or country. From these causes were derived, 1. The exquisite sensibility of the sufferers; and, 2. The impossibility of escaping from the hand of the oppressor.

I. When Persia was governed by the descendants of Sefi, a race of princes whose wanton cruelty often stained their divan, their table, and their bed, with the blood of their favorites, there is a saying recorded of a young nobleman, that he never departed from the sultan's presence, without satisfying himself whether his head was still on his shoulders. The experience of every day might almost justify the scepticism of Rustan. Yet the fatal sword, suspended above him by a single thread, seems not to have disturbed the slumbers, or interrupted the tranquillity, of the Persian. The monarch's frown, he well knew, could level him with the dust; but the stroke of lightning or apoplexy might be equally fatal; and it was the part of a wise man to forget the inevitable calamities of human life in the enjoyment of the fleeting hour. He was dignified with the appellation of the king's slave; had, perhaps, been purchased from obscure parents,
