To the preceding maybe added Theodosius the Great, the last Roman emperor before the division of the empire. He was a member of the Christian church, and in his zeal against paganism, and what he deemed heresy, surpassed all who were before him. The Christian writers of his time speak of him as a most illustrious model of justice, generosity, magnanimity, benevolence, and every virtue. And yet Theodosius denounced capital punishments against those who held 'heretical' opinions, and commanded inter-marriage between cousins to be punished by burning the parties alive. On hearing that the people of Antioch had demolished the statues set up in that city, in honor of himself, and had threatened the governor, he flew into a transport of fury, ordered the city to be laid in ashes, and all the inhabitants to be slaughtered; and upon hearing of a resistance to his authority in Thessalonica, in which one of his lieutenants was killed, he instantly ordered a _general massacre_ of the inhabitants; and in obedience to his command, seven thousand men, women and children were butchered in the space of three hours. The foregoing are a few of many instances in the history of Rome, and of a countless multitude in the history of the world, illustrating the truth, that the lodgement of arbitrary power, in the best human hands, is always a fearfully perilous experiment; that the mildest tempers, the most humane and benevolent dispositions, the most blameless and conscientious previous life, with the most rigorous habits of justice, are no security, that, in a moment of temptation, the possessors of such power will not make their subjects their victims; illustrating also the truth, that, while men may exhibit nothing but honor, honesty, mildness, justice, and generosity, in their intercourse with those of their own grade, or language, or nation, or hue, they may practice towards others, for whom they have contempt and aversion, the most revolting meanness, perpetrate robbery unceasingly, and inflict the severest privations, and the most barbarous cruelties. But this is not all: history is full of examples, showing not only the effects of arbitrary power on its victims, but its terrible reaction on those who exercise it; blunting their sympathies, and hardening to adamant their hearts toward _them_, at least, if not toward the human race generally. This is shown in the fact, that almost every tyrant in the history of the world, has entered upon the exercise of absolute power with comparative moderation; multitudes of them with marked forbearance and mildness, and not a few with the most signal condescension, magnanimity, gentleness and compassion. Among these last are included those who afterwards became the bloodiest monsters that ever cursed the earth. Of the Roman Emperors, almost every one of whom perpetrated the most barbarous atrocities, Vitellius seems to have been the only one who cruelly exercised his power from the _outset_.
