25. After they had seen all, the spies departed to go back; and when they reported these things, forthwith Cambyses was enraged and proceeded to march his army against the Ethiopians, not having ordered any provision of food nor considered with himself that he was intending to march an army to the furthest extremities of the earth; but as one who is mad and not in his right senses, when he heard the report of the Ichthyophagoi he began the march, ordering those of the Hellenes who were present to remain behind in Egypt, and taking with him his whole land force: and when in the course of his march he had arrived at Thebes, he divided off about fifty thousand of his army, and these he enjoined to make slaves of the Ammonians and to set fire to the seat of the Oracle of Zeus, but he himself with the remainder of his army went on against the Ethiopians. But before the army had passed over the fifth part of the way, all that they had of provisions came to an end completely; and then after the provisions the beasts of burden also were eaten up and came to an end. Now if Cambyses when he perceived this had changed his plan and led his army back, he would have been a wise man in spite of his first mistake; as it was, however, he paid no regard, but went on forward without stopping. The soldiers accordingly, so long as they were able to get anything from the ground, prolonged their lives by eating grass; but when they came to the sand, some did a fearful deed, that is to say, out of each company of ten they selected by lot one of themselves and devoured him: and Cambyses, when he heard it, being alarmed by this eating of one another gave up the expedition against the Ethiopians and set forth to go back again; and he arrived at Thebes having suffered loss of a great number of his army. Then from Thebes he came down to Memphis and allowed the Hellenes to sail away home.
26. 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 upon the forehead, and on the back the likeness of an eagle, and in the tail the hairs are double, and on the tongue there is a mark like a beetle.
29. When the priests had brought Apis, Cambyses being somewhat affected with madness drew his dagger, and aiming at the belly of Apis, struck his thigh: then he laughed and said to the priests: "O ye wretched creatures, are gods born such as this, with blood and flesh, and sensible of the stroke of iron weapons? Worthy indeed of Egyptians is such a god as this. Ye however at least shall not escape without punishment for making a mock of me." Having thus spoken he ordered those whose duty it was to do such things, to scourge the priests without mercy, and to put to death any one of the other Egyptians whom they should find keeping the festival. Thus the festival of the Egyptians had been brought to an end, and the priests were being chastised, and Apis wounded by the stroke in his thigh lay dying in the temple.
