When Cambyses was back at Mit Rahina [31.25,29.85] (inhabited place), Giza, Upper Egypt, Egypt, AfricaMemphis, there appeared in Egypt [30,27] (nation), Africa Egypt that Apis [*](cp. Hdt. 2.38.) whom the Greeks call Epaphus; at whose epiphany the Egyptians put on their best clothing and held a festival.
Seeing the Egyptians so doing, Cambyses was fully persuaded that these signs of joy were for his misfortunes, and summoned the rulers of Mit Rahina [31.25,29.85] (inhabited place), Giza, Upper Egypt, Egypt, AfricaMemphis; when they came before him, he asked them why the Egyptians behaved so at the moment he returned with so many of his army lost, though they had done nothing like it when he was before at Mit Rahina [31.25,29.85] (inhabited place), Giza, Upper Egypt, Egypt, AfricaMemphis.
The rulers told him that a god, wont to appear after long intervals of time, had now appeared to them; and that all Egypt [30,27] (nation), Africa Egypt rejoiced and made holiday whenever he so appeared. At this Cambyses said that they lied, and he punished them with death for their lie.
Having put them to death, he next summoned the priests before him. When they gave him the same account, he said that if a tame god had come to the Egyptians he would know it; and with no more words he bade the priests bring Apis. So they went to fetch and bring him.
This Apis, or Epaphus, is a calf born of a cow that can never conceive again. By what the Egyptians say, the cow is made pregnant by a light from heaven, and thereafter gives birth to Apis.
The marks of this calf called Apis are these: he is black, and has on his forehead a three-cornered white spot, and the likeness of an eagle on his back; the hairs of the tail are double, and there is a knot under the tongue.
