When Persian history first fairly opens upon us in the pages of Xenophon and of Nicolaus Damascenus, this is the condition of things which we find existing. Cambyses, the father of Cyrus the Great--called Atradates by the Syrian writer--is ruler of Persia, and resides in his native country, while his son Cyrus is permanently, or at any rate usually, resident at the Median Court, where he is in high favor with the reigning monarch, Astyages. According to Xenophon, who has here the support of Herodotus, he is Astyages’ grandson, his father, Cambyses, being married to Mandane, that monarch’s daughter. According to Nicolaus, who in this agrees with Ctesias, he is no way related to Astyages, who retains him at his court because he is personally attached to him. In the narrative of the latter writer, which has already been preferred in these volumes, the young prince, while at the Court, conceives the idea of freeing his own country by a revolt, and enters into secret communication with his father for the furtherance of his object. His father somewhat reluctantly assents, and preparations are made, which lead to the escape of Cyrus and the commencement of a war of independence. The details of the struggle, as they are related by Nicolaus, have been already given. After repeated defeats, the Persians finally make a stand at Pasargadae, their capital, where in two great battles they destroy the power of Astyages, who himself remains a prisoner in the hands of his adversary. In the course of the struggle the father of Cyrus had fallen, and its close, therefore, presented Cyrus himself before the eyes of the Western Asiatics as the undisputed lord of the great Arian Empire which had established itself on the ruins of the Semitic. Transfers of sovereignty are easily made in the East, where independence is little valued, and each new conqueror is hailed with acclamations from millions. It mattered nothing to the bulk of Astyages’ subjects whether they were ruled from Ecbatana or Pasargadae, by Median or Persian masters. Fate had settled that a single lord was to bear sway over the tribes and nations dwelling between the Persian Gulf and the Euxine; and the arbitrament of the sword had now decided that this single lord should be Cyrus. We may readily believe the statement of Nicolaus that the nations previously subject to the Medes vied with each other in the celerity and zeal with which they made their submission to the Persian conqueror. Cyrus succeeded at once to the full inheritance of which he had dispossessed Astyages, and was recognized as king by all the tribes between the Halys and the desert of Khorassan.
