After this, when the bone had become diseased and the thigh had mortified, Cambyses the son of Cyrus was carried off by the wound, having reigned in all seven years and five months, and being absolutely childless both of male and female offspring. The Persians meanwhile who were present there were very little disposed to believe 57 that the power was in the hands of the Magians: on the contrary, they were surely convinced that Cambyses had said that which he said about the death of Smerdis to deceive them, in order that all the Persians might be moved to war against him. These then were surely convinced that Smerdis the son of Cyrus was established to be king; for Prexaspes also very strongly denied that he had slain Smerdis, since it was not safe, now that Cambyses was dead, for him to say that he had destroyed with his own hand the son of Cyrus.
67. Thus when Cambyses had brought his life to an end, the Magian became king without disturbance, usurping the place of his namesake Smerdis the son of Cyrus; and he reigned during the seven months which were wanting yet to Cambyses for the completion of the eight years: and during them he performed acts of great benefit to all his subjects, so that after his death all those in Asia except the Persians themselves mourned for his loss: for the Magian sent messengers abroad to every nation over which he ruled, and proclaimed freedom from military service and from tribute for three years.
68. This proclamation, I say, he made at once when he established himself upon the throne: but in the eighth month it was discovered who he was in the following manner:—There was one Otanes the son of Pharnaspes, in birth and in wealth not inferior to any of the Persians. This Otanes was the first who had had suspicion of the Magian, that he was not Smerdis the son of Cyrus but the person that he really was, drawing his inference from these facts, namely that he never went abroad out of the fortress, and that he did not summon into his presence any of the honourable men among the Persians: and having formed a suspicion of him, he proceeded to do as follows:—Cambyses had taken to wife his daughter, whose name was Phaidyme; 58 and this same daughter the Magian at that time was keeping as his wife and living with her as with all the rest also of the wives of Cambyses. Otanes therefore sent a message to this daughter and asked her who the man was by whose side she slept, whether Smerdis the son of Cyrus or some other. She sent back word to him saying that she did not know, for she had never seen Smerdis the son of Cyrus, nor did she know otherwise who he was who lived with her. Otanes then sent a second time and said: "If thou dost not thyself know Smerdis the son of Cyrus, then do thou ask of Atossa who this man is, with whom both she and thou live as wives; for assuredly it must be that she knows her own brother."
