Thus fared the expedition against the Ethiopians: and those of the Persians who had been sent to march against the Ammonians set forth from Thebes and went on their way with guides; and it is known that they arrived at the city of Oasis, which is inhabited by Samians said to be of the Aischrionian tribe, and is distant seven days' journey from Thebes over sandy desert: now this place is called in the speech of the Hellenes the "Isle of the Blessed." It is said that the army reached this place, but from that point onwards, except the Ammonians themselves and those who have heard the account from them, no man is able to say anything about them; for they neither reached the Ammonians nor returned back. This however is added to the story by the Ammonians themselves:—they say that as the army was going from this Oasis through the sandy desert to attack them, and had got to a point about mid-way between them and the Oasis, while they were taking their morning meal a violent South Wind blew upon them, and bearing with it heaps of the desert sand it buried them under it, and so they disappeared and were seen no more. Thus the Ammonians say that it came to pass with regard to this army.
27. When Cambyses arrived at Memphis, Apis appeared to the Egyptians, whom the Hellenes call Epaphos: and when he had appeared, forthwith the Egyptians began to wear their fairest garments and to have festivities. Cambyses accordingly seeing the Egyptians doing thus, and supposing that they were certainly acting so by way of rejoicing because he had fared ill, called for the officers who had charge of Memphis; and when they had come into his presence, he asked them why when he was at Memphis on the former occasion, the Egyptians were doing nothing of this kind, but only now, when he came there after losing a large part of his army. They said that a god had appeared to them, who was wont to appear at intervals of long time, and that whenever he appeared, then all the Egyptians rejoiced and kept festival. Hearing this Cambyses said that they were lying, and as liars he condemned them to death.
28. Having put these to death, next he called the priests into his presence; and when the priests answered him after the same manner, he said that it should not be without his knowledge if a tame god had come to the Egyptians; and having so said he bade the priests bring Apis away into his presence: so they went to bring him. Now this Apis-Epaphos is a calf born of a cow who after this is not permitted to conceive any other offspring; and the Egyptians say that a flash of light comes down from heaven upon this cow, and of this she produces Apis. This calf which is called Apis is black and has the following signs, namely a white square 23 upon the forehead, and on the back the likeness of an eagle, and in the tail the hairs are double, and on 24 the tongue there is a mark like a beetle.
