(M178) Learning from these Scythian invaders many arts, not before practiced in war, such as archery and cavalry movements, Cyaxares was prepared to extend his empire to the west over Armenia and Asia Minor, as far as the river Halys. He made war in Lydia with the father of Crœsus. But before these conquests were made, he probably captured Nineveh and destroyed it, B.C. 625. He was here assisted by the whole force of the Babylonians, under Nabopolassar, an old general of the Assyrians, but who had rebelled. In reward he obtained for his son, Nebuchadnezzar, the hand of the daughter of Cyaxares. The last of the Assyrian monarchs, whom the Greeks have called Sardanapalus, burned himself in his palace rather than fall into the hands of the Median conqueror. (M179) The fall of Nineveh led to the independence of Babylon, and its wonderful growth, and also to the conquests of the Medes as far as Lydia to the west. The war with Lydia lasted six years, and was carried on with various success, until peace was restored by the mediation of a Babylonian prince. The reason that peace was made was an eclipse of the sun, which happened in the midst of a great battle, which struck both armies with superstitious fears. On the conclusion of peace, the son of the Median king, Astyages, married the daughter of the Lydian monarch, Alyattes, and an alliance was formed between Media and Lydia. (M180) At this time Lydia comprised nearly all of Asia Minor, west of the Halys. The early history of this country is involved in obscurity. The dynasty on the throne, when invaded by the Medes, was founded by Gyges, B.C. 724, who began those aggressions on the Grecian colonies which were consummated by Crœsus. Under the reign of Ardys, his successor, Asia Minor was devastated by the Cimmerians, a people who came from the regions north of the Black Sea, between the Danube and the Sea of Azov, being driven away by an inundation of Scythians, like that which afterward desolated Media. These Cimmerians, having burned the great temple of Diana, at Ephesus, and destroyed the capital city of Sardis, were expelled from Lydia by Alyattes, the monarch against whom Cyaxares had made war.
