122. After these things they said this king went down alive to that place which by the Hellenes is called Hades, and there played at dice with Demeter, and in some throws he overcame her and in others he was overcome by her; and he came back again having as a gift from her a handkerchief of gold: and they told me that because of the going down of Rhampsinitos the Egyptians after he came back celebrated a feast, which I know of my own knowledge also that they still observe even to my time; but whether it is for this cause that they keep the feast or for some other, I am not able to say. However, the priests weave a robe completely on the very day of the feast, and forthwith they bind up the eyes of one of them with a fillet, and having led him with the robe to the way by which one goes to the temple of Demeter, they depart back again themselves. This priest, they say, with his eyes bound up is led by two wolves to the temple of Demeter, which is distant from the city twenty furlongs*, and then afterwards the wolves lead him back again from the temple to the same spot.
123. Now as to the tales told by the Egyptians, any man may accept them to whom such things appear credible; as for me, it is to be understood throughout the whole of the history that I write by hearsay that which is reported by the people in each place. The Egyptians say that Demeter and Dionysos are rulers of the world below; and the Egyptians are also the first who reported the doctrine that the soul of man is immortal, and that when the body dies, the soul enters into another creature which chances then to be coming to the birth, and when it has gone the round of all the creatures of land and sea and of the air, it enters again into a human body as it comes to the birth; and that it makes this round in a period of three thousand years. This doctrine certain Hellenes adopted, some earlier and some later, as if it were of their own invention, and of these men I know the names but I abstain from recording them.
