But Cambyses, the Egyptians say, owing to this wrongful act immediately went mad, although even before he had not been sensible. His first evil act was to destroy his full brother Smerdis, whom he had sent away from Egypt to Persia out of jealousy, because Smerdis alone could draw the bow brought from the Ethiopian by the Fish-eaters as far as two fingerbreadths, but no other Persian could draw it. Smerdis having gone to Persia , Cambyses saw in a dream a vision, in which it seemed to him that a messenger came from Persia and told him that Smerdis sitting on the royal throne touched heaven with his head. Fearing therefore for himself, lest his brother might slay him and so be king, he sent Prexaspes, the most trusted of his Persians, to Persia to kill him. Prexaspes went up to Susa and killed Smerdis; some say that he took Smerdis out hunting, others that he brought him to the Red Sea and there drowned him.
