Of his real exploits, we know little except their results; but in what we read respecting him there seems, though amidst constant fighting, very little cruelty. Xenophon has selected his life as the subject of a moral romance, which for a long time was cited as authentic history, and which even now serves as an authority, expressed or implied, for disputable and even incorrect conclusions. His extraordinary activity and conquests admit of no doubt. He left the Persian empire[379] extending from Sogdiana and the rivers Jaxartês and Indus eastward, to the Hellespont and the Syrian coast westward, and his successors made no permanent addition to it except that of Egypt. Phenicia and Judæa were dependencies of Babylon, at the time when he conquered it, with their princes and grandees in Babylonian captivity. They seem to have yielded to him, and become his tributaries,[380] without difficulty; and the restoration of their captives was conceded to them. It was from Cyrus that the habits of the Persian kings took commencement, to dwell at Susa in the winter, and Ekbatana during the summer; the primitive territory of Persis, with its two towns of Persepolis and Pasargadæ, being reserved for the burial-place of the kings and the religious sanctuary of the empire. How or when the conquest of Susiana was made, we are not informed; it lay eastward of the Tigris, between Babylonia and Persis proper, and its people, the Kissians, as far as we can discern, were of Assyrian and not of Arian race. The river Choaspês, near Susa, was supposed to furnish the only water fit for the palate of the Great King, and is said to have been carried about with him wherever he went.[381] [379] The town Kyra, or Kyropolis, on the river Sihon, or Jaxartês, was said to have been founded by Cyrus,—it was destroyed by Alexander (Strabo, xi, pp. 517, 518; Arrian, iv, 2, 2; Curtius, vii, 6, 16).
