thus the Romans, about ten years before the fall of the Parthian monarchy, obtained a firm and permanent establishment beyond the Euphrates.

Prudence as well as glory might have justified a war on the side of Artaxerxes, had his views been confined to the defence or acquisition of a useful frontier. but the ambitious Persian openly avowed a far more extensive design of conquest; and he thought himself able to support his lofty pretensions by the arms of reason as well as by those of power. Cyrus, he alleged, had first subdued, and his successors had for a long time possessed, the whole extent of Asia, as far as the Propontis and the Ægean Sea; the provinces of Caria and Ionia, under their empire, had been governed by Persian satraps, and all Egypt, to the confines of Æthiopia, had acknowledged their sovereignty. Their rights had been suspended, but not destroyed, by a long usurpation; and as soon as he received the Persian diadem, which birth and successful valor had placed upon his head, the first great duty of his station called upon him to restore the ancient limits and splendor of the monarchy. The Great King, therefore, (such was the haughty style of his embassies to the emperor Alexander,) commanded the Romans instantly to depart from all the provinces of his ancestors, and, yielding to the Persians the empire of Asia, to content themselves with the undisturbed possession of Europe. This haughty mandate was delivered by four hundred of the tallest and most beautiful of the Persians; who, by their fine horses, splendid arms, and rich apparel, displayed the pride and greatness of their master. Such an embassy was much less an offer of negotiation than a declaration of war. Both Alexander Severus and Artaxerxes, collecting the military force of the Roman and Persian monarchies, resolved in this important contest to lead their armies in person.

If we credit what should seem the most authentic of all records, an oration, still extant, and delivered by the emperor himself to the senate, we must allow that the victory of Alexander Severus was not inferior to any of those formerly obtained over the Persians by the son of Philip. The army of the Great King consisted of one hundred and twenty thousand horse, clothed in complete armor of steel; of seven hundred elephants, with towers filled with archers on their backs, and of eighteen hundred chariots armed with scythes. This formidable host, the like of which is not to be found in eastern history, and has scarcely been imagined in eastern romance, was discomfited in a great battle, in which the Roman Alexander proved himself an intrepid soldier and a skilful general. The Great King fled before his valor; an immense booty, and the conquest of Mesopotamia, were the immediate fruits of this signal victory. Such are the circumstances of this ostentatious and improbable relation, dictated, as it too plainly appears, by the vanity of the monarch, adorned by the unblushing servility of his flatterers, and received without contradiction by a distant and obsequious senate. Far from being inclined to believe that the arms of Alexander obtained any memorable advantage over the Persians, we are induced to suspect that all this blaze of imaginary glory was designed to conceal some real disgrace.

Our suspicious are confirmed by the authority of a contemporary historian, who mentions the virtues of Alexander with respect, and his faults with candor. He describes the judicious plan which had been formed for the conduct of the war. Three Roman armies were destined to invade Persia at the same time, and by different roads. But the operations of the campaign, though wisely concerted, were not executed either with ability or success. The first of these armies, as soon as it had entered the marshy plains of Babylon, towards the artificial conflux of the Euphrates and the Tigris, was encompassed by the superior numbers, and destroyed by the arrows of the enemy. The alliance of Chosroes, king of Armenia, and the long tract of mountainous country, in which the Persian cavalry was of little service, opened a secure entrance into the heart of Media, to the second of the Roman armies. These brave troops laid waste the adjacent provinces, and by several successful actions against Artaxerxes, gave a faint color to the emperor's vanity. But the retreat of this victorious army was imprudent, or at least unfortunate. In repassing the mountains, great numbers of soldiers perished by the badness of the roads, and the severity of the winter season. It had been resolved, that whilst these two great detachments penetrated into the opposite extremes of the Persian dominions, the main body, under the command of Alexander himself, should support their attack, by invading the centre of the kingdom. But the unexperienced youth, influenced by his mother's counsels, and perhaps by his own fears, deserted the bravest troops, and the fairest prospect of victory; and after consuming in Mesopotamia an inactive and inglorious summer, he led back to Antioch an army diminished by sickness, and provoked by disappointment.
