When Prexaspes said that he was ready to do this too, the Magi summoned the Persians together, and brought him up on to a tower and bade him speak. Then, deliberately forgetting all the Magi's instructions, he traced the lineage of Cyrus from Achaemenes downwards; when he came at last to the name of Cyrus, he recounted all the good which that king had done to Persia , and after he had narrated this, he revealed the truth, saying that he had concealed it before, as it had not been safe for him to tell what had happened, but at the present time necessity forced him to reveal it: and he said that he himself, forced by Cambyses, had killed Smerdis son of Cyrus, and that the Magi were in power. Then, invoking a terrible curse on the Persians if they did not win back the throne and take vengeance on the Magi, he threw himself headlong down from the tower; so Prexaspes, a man who was always well thought of, perished in this way.
