Page: 69. With such words as these he resisted, fearing lest some evil might come to him from this; but the king answered him thus: "Be of good courage, Gyges, and have no fear, either of me, that I am saying these words to try thee, or of my wife, lest any harm may happen to thee from her. For I will contrive it so from the first that she shall not even perceive that she has been seen by thee. I will place thee in the room where we sleep, behind the open door; 7 and after I have gone in, my wife also will come to lie down. Now there is a seat near the entrance of the room, and upon this she will lay her garments as she takes them off one by one; and so thou wilt be able to gaze upon her at full leisure. And when she goes from the chair to the bed and thou shalt be behind her back, then let it be thy part to take care that she sees thee not as thou goest through the door."
10. He then, since he might not avoid it, gave consent: and Candaules, when he considered that it was time to rest, led Gyges to the chamber; and straightway after this the woman also appeared: and Gyges looked upon her after she came in and as she laid down her garments; and when she had her back turned towards him, as she went to the bed, then he slipped away from his hiding-place and was going forth. And as he went out, the woman caught sight of him, and perceiving that which had been done by her husband she did not cry out, though struck with shame, 8 but she made as though she had not perceived the matter, meaning to avenge herself upon Candaules: for among the Lydians as also among most other Barbarians it is a shame even for a man to be seen naked.
11. At the time then she kept silence, as I say, and made no outward sign; but as soon as day had dawned, and she made ready those of the servants whom she perceived to be the most attached to herself, and after that she sent to summon Gyges. He then, not supposing that anything of that which had been done was known to her, came upon her summons; for he had been accustomed before to go 9 whenever the queen summoned him. And when Gyges was come, the woman said to him these words: "There are now two ways open to thee, Gyges, and I give thee the choice which of the two thou wilt prefer to take. Either thou must slay Candaules and possess both me and the kingdom of Lydia, or thou must thyself here on the spot be slain, so that thou mayest not in future, by obeying Candaules in all things, see that which thou shouldest not. Either he must die who formed this design, or thou who hast looked upon me naked and done that which is not accounted lawful." For a time then Gyges was amazed at these words, and afterwards he began to entreat her that she would not bind him by necessity to make such a choice: then however, as he could not prevail with her, but saw that necessity was in truth set before him either to slay his master or to be himself slain by others, he made the choice to live himself; and he inquired further as follows: "Since thou dost compel me to take my master's life against my own will, let me hear from thee also what is the manner in which we shall lay hands upon him." And she answering said: "From that same place shall the attempt be, where he displayed me naked; and we will lay hands upon him as he sleeps."
