Artaxerxes, however, resisted in this quarter, and unable to overcome the resistance, which he may have regarded as deriving its effectiveness (in part at least) from the support lent it by Rome, determined (ab. A.D. 229) to challenge the empire to an encounter. Aware that Artabanus, his late rival, against whom he had measured himself, and whose power he had completely overthrown, had been successful in his war with Macrinus, had gained the great battle of Nisibis, and forced the Imperial State to purchase an ignominious peace by a payment equal to nearly two millions of our money, he may naturally have thought that a facile triumph was open to his arms in this direction. Alexander Severus, the occupant of the imperial throne, was a young man of a weak character, controlled in a great measure by his mother, Julia Mamaea, and as yet quite undistinguished as a general. The Roman forces in the East were known to be licentious and insubordinate; corrupted by the softness of the climate and the seductions of Oriental manners, they disregarded the restraints of discipline, indulged in the vices which at once enervate the frame and lower the moral character, had scant respect for their leaders, and seemed a defence which it would be easy to overpower and sweep away. Artaxerxes, like other founders of great empires, entertained lofty views of his abilities and his destinies; the monarchy which he had built up in the space of some five or six years was far from contenting him; well read in the ancient history of his nation, he sighed after the glorious days of Cyrus the Great and Darius Hystaspis, when all Western Asia from the shores of the AEgean to the Indian desert, and portions of Europe and Africa, had acknowledged the sway of the Persian king. The territories which these princes had ruled he regarded as his own by right of inheritance; and we are told that he not only entertained, but boldly published, these views. His emissaries everywhere declared that their master claimed the dominion of Asia as far as the AEgean Sea and the Propontis. It was his duty and his mission to recover to the Persians their pristine empire. What Cyrus had conquered, what the Persian kings had held from that time until the defeat of Codomannus by Alexander, was his by indefeasible right, and he was about to take possession of it.
