Only a few short fragments remain of the account given by Diodorus of the overthrow of Astyages. With him Cyrus is the son of Mandane, the daughter of Astyages, and Cambyses. His father brought him up as a king, and inflamed him with a desire for the mightiest achievements. As a young man he displayed a capacity in advance of his years, and clearly showed that he would undertake the most important enterprises. He was the first man of his time in bravery, wisdom, and all other virtues. Another fragment obviously comes after the defeat, which, according to Nicolaus, Astyages suffered in the final battle at Pasargadae. When defeated, Astyages, though he had himself disgracefully turned and fled, showed ferocious anger against his army. He deposed all the commanders and elected others in their place. Those who were to blame for the flight, he executed one and all, thinking that he should thus compel the others to show themselves brave men in danger. "For he was cruel and harsh in character. But he did not terrify the multitude by this severity; on the other hand, by the exasperation which such violence and caprice excited in every one, he roused them to a desire for revolution and deposition. The troops met in their divisions; treasonable speeches were uttered, and the majority urged each other to vengeance."[538] Xenophon, it is true, has not written a history of Cyrus, but has given a description of his life from his knowledge of the Persian life and character, and the conclusions he deduced therefrom, as to the possible origin of the empire, in order to explain and realise to the Greeks the difficulty which they found it so hard to solve--the manner in which great nations could form one community and be governed by one person. With him Cyrus is the son of Cambyses, who is the king of the Persians, and Mandane the daughter of Astyages of Media, whom Xenophon represents as reigning before Cyaxares. When Cyrus was twelve years of age, his mother went with him to Media, in order to show him to his grandfather, whom the boy astonished by his apt answers. At the age of sixteen, Cyrus performs his first deeds of arms. When Astyages died, he was succeeded on the throne by his son Cyaxares, the brother of Mandane. He entreats Cambyses to aid him against the Assyrians; Cambyses sends Cyrus, by whose services the Medes are defeated. After this he conquered the Lydians, who had come to aid the Assyrians against the Medes, and took Babylon; and his uncle Cyaxares, whom Xenophon does not describe as a pattern ruler, gives him his daughter in marriage, and Media as a dowry, for he was without male children. Cambyses and Mandane assented to this arrangement. After the death of Cambyses, Cyrus became king of Persia, and on the death of Cyaxares, Media also became his.
