The reign of Artaxerxes, which, from the last defeat of the Parthians, lasted only fourteen years, forms a memorable æra in the history of the East, and even in that of Rome. His character seems to have been marked by those bold and commanding features, that generally distinguish the princes who conquer, from those who inherit, an empire. Till the last period of the Persian monarchy, his code of laws was respected as the groundwork of their civil and religious policy. Several of his sayings are preserved. One of them in particular discovers a deep insight into the constitution of government. “The authority of the prince,” said Artaxerxes, “must be defended by a military force; that force can only be maintained by taxes; all taxes must, at last, fall upon agriculture; and agriculture can never flourish except under the protection of justice and moderation.” Artaxerxes bequeathed his new empire, and his ambitious designs against the Romans, to Sapor, a son not unworthy of his great father; but those designs were too extensive for the power of Persia, and served only to involve both nations in a long series of destructive wars and reciprocal calamities. The Persians, long since civilized and corrupted, were very far from possessing the martial independence, and the intrepid hardiness, both of mind and body, which have rendered the northern barbarians masters of the world. The science of war, that constituted the more rational force of Greece and Rome, as it now does of Europe, never made any considerable progress in the East. Those disciplined evolutions which harmonize and animate a confused multitude, were unknown to the Persians. They were equally unskilled in the arts of constructing, besieging, or defending regular fortifications. They trusted more to their numbers than to their courage; more to their courage than to their discipline. The infantry was a half-armed, spiritless crowd of peasants, levied in haste by the allurements of plunder, and as easily dispersed by a victory as by a defeat. The monarch and his nobles transported into the camp the pride and luxury of the seraglio. Their military operations were impeded by a useless train of women, eunuchs, horses, and camels; and in the midst of a successful campaign, the Persian host was often separated or destroyed by an unexpected famine.
