To this the daughter sent back word: "I am not able either to come to speech with Atossa or to see any other of the women who live here with me; for as soon as this man, whosoever he may be, succeeded to the kingdom, he separated us and placed us in different apartments by ourselves." When Otanes heard this, the matter became more and more clear to him, and he sent another message in to her, which said: "Daughter, it is right for thee, nobly born as thou art, to undertake any risk which thy father bids thee take upon thee: for if in truth this is not Smerdis the son of Cyrus but the man whom I suppose, he ought not to escape with impunity either for taking thee to his bed or for holding the dominion of Persians, but he must pay the penalty. Now therefore do as I say. When he sleeps by thee and thou perceivest that he is sound asleep, feel his ears; and if it prove that he has ears, then believe that thou art living with Smerdis the son of Cyrus, but if not, believe that it is with the Magian Smerdis." To this Phaidyme sent an answer saying that, if she should do so, she would run a great risk; for supposing that he should chance not to have his ears, and she were detected feeling for them, she was well assured that he would put her to death; but nevertheless she would do this. So she undertook to do this for her father: but as for this Magian Smerdis, he had had his ears cut off by Cyrus the son of Cambyses when he was king, for some grave offence. This Phaidyme then, the daughter of Otanes, proceeding to perform all that she had undertaken for her father, when her turn came to go to the Magian (for the wives of the Persians go in to them regularly each in her turn), came and lay down beside him: and when the Magian was in deep sleep, she felt his ears; and perceiving not with difficulty but easily that her husband had no ears, so soon as it became day she sent and informed her father of that which had taken place.

Then Otanes took to him Aspathines and Gobryas, 59 who were leading men among the Persians and also his own most trusted friends, and related to them the whole matter: and they, as it then appeared, had suspicions also themselves that it was so; and when Otanes reported this to them, they readily accepted his proposals. Then it was resolved by them that each one should associate with himself that man of the Persians whom he trusted most; so Otanes brought in Intaphrenes, 60 Gobryas brought in Megabyzos, and Aspathines brought in Hydarnes. When they had thus become six, Dareios the son of Hystaspes arrived at Susa, having come from the land of Persia, for of this his father was governor. Accordingly when he came, the six men of the Persians resolved to associate Dareios also with themselves.
