Xenophon, Cyropaedia
Walter Miller, Ed.

But all this is not so surprising after all, so very different was he from all other kings, both those who have inherited their thrones from their fathers and those who have gained their crowns by their own efforts; the Scythian king, for instance, would never be able to extend his rule over any other nation besides his own, although the Scythians are very numerous, but he would be well content if he could maintain himself in power over his own people; so the Thracian king with his Thracians, the Illyrian with his Illyrians, and so also all other nations, we are told. Those in Europe, at any rate, are said to be free and independent of one another even to this day. But Cyrus, finding the nations in Asia also independent in exactly the same way, started out with a little band of Persians and became the leader of the Medes by their full consent and of the Hyrcanians¹ by theirs; he then conquered Syria, Assyria, Arabia, Cappadocia, both Phrygias, Lydia, Caria, Phoenicia, and Babylonia; he ruled also over Bactria, India, and Cilicia; and he was likewise king of the Sacians, Paphlagonians, Magadidae, and very many other nations, of which one could not even tell the names; he brought under his sway the Asiatic Greeks also; and, descending to the sea, he added both Cyprus and Egypt to his empire.
