Cambyses liked Prexaspes' advice; the herald was pursued at once and brought; and when he came, Prexaspes put this question to him: “Fellow, you say that your message is from Cyrus' son Smerdis; tell me this now, and you may go away unpunished: was it Smerdis who appeared to you and gave you this charge, or was it one of his servants?” “Since King Cambyses marched to Egypt ,” answered the herald, “I have never seen Smerdis the son of Cyrus; the Magus whom Cambyses made overseer of his house gave me the message, saying that it was the will of Smerdis, son of Cyrus, that I should make it known to you.” So spoke the herald, telling the whole truth; and Cambyses said, “Prexaspes, having done what you were told like a good man you are free of blame; but who can this Persian be who rebels against me and usurps the name of Smerdis?” Prexaspes replied, “I think, sire, that I understand what has been done here; the rebels are the Magi, Patizeithes whom you left steward of your house, and his brother Smerdis.”
