anything at once so great and so beneficent as the government of Hadrian. But one thing was wanting to the many-tongued and many-tempered peoples ruled by him, that they should of their own will accept the worship of one God, and so the matchless empire receive the only true principle of coherence and permanence in the common possession of one religion. And the thoughtful student of history can hardly restrain himself from indulging his fancy as to what might then have been the result, and into how great a structure provinces worthy of being kingdoms might then have grown by the process of an unbroken civilisation instinct with the principles of the pure Christian Faith. Then the northern flood of barbarism and the eastern tempest of a false religion, which together were to break up the fabric of a thousand years, might have been beaten back from its boundaries, and from them the messengers of light have so penetrated the world in all directions that the advance of the truth should not have been impeded by any great civil destruction, but the nations of Europe have developed themselves from their Roman cradle by a continuous growth, in which there had been no ages of conquest, violence, and confusion, no relapse into chaos, no struggle back into an intricate and yet imperfect order, but the serene advance from dawn to day. So, however, it was not to be. The time of probation in the reigns of Hadrian and Antoninus Pius, wherein a sort of toleration had seemed to be allowed to Christians, passed away, and the beginning of a far different destiny broke upon the empire. With the accession of Marcus Aurelius the great old enemies, the North and the East, awoke from their trance in fresh vigour. A Parthian war of four years, a German war of twelve, with pestilence, earthquakes, and famines through a large part of the empire, try to the utmost the vigour and temper of one of the most upright sovereigns known to heathenism. Marcus Aurelius meets both enemies with equal courage and ability, but he dies prematurely, and leaves the rule carried so temperately by four great sovereigns successively adopted to empire at mature age, in the untried hands of the heir of his blood, a youth of nineteen, born in the purple. In this at least the great Roman was wanting both to Stoic greatness and to Roman duty. And it was a fatal error. During thirteen years this son of the most virtuous heathen shows himself the most vicious of tyrants. At a single bound Rome passes from a ruler more just than Trajan to a ruler more abandoned than Nero; and in the palace of Marcus Aurelius endures an emperor who has a double harem of three hundred victims;(197) who spares the blood of no senator, and respects the worth of no officer.
