When Cyrus had brought his life to an end, Cambyses received the royal power in succession, being the son of Cyrus and of Cassandane the daughter of Pharnaspes, for whose death, which came about before his own, Cyrus had made great mourning himself and also had proclaimed to all those over whom he bore rule that they should make mourning for her: Cambyses, I say, being the son of this woman and of Cyrus, regarded the Ionians and Aiolians as slaves inherited from his father; and he proceeded to march an army against Egypt, taking with him as helpers not only other nations of which he was ruler, but also those of the Hellenes over whom he had power besides.
