all beat themselves for mourning, and when they have finished beating themselves they set forth as a feast that which they left unburnt of the sacrifice.  The clean males then of the ox kind, both full-grown animals and calves, are sacrificed by all the Egyptians; the females however they may not sacrifice, but these are sacred to Isis; for the figure of Isis is in the form of a woman with cow’s horns, just as the Hellenes present Io in pictures, and all the Egyptians without distinction reverence cows far more than any other kind of cattle; for which reason neither man nor woman of the Egyptian race would kiss a man who is a Hellene on the mouth, nor will they use a knife or roasting-spits or a caldron belonging to a Hellene, nor taste the flesh even of a clean animal if it has been cut with the knife of a Hellene.  And the cattle of this kind which die they bury in the following manner:—­the females they cast into the river, but the males they bury, each people in the suburb of their town, with one of the horns, or sometimes both, protruding to mark the place; and when the bodies have rotted away and the appointed time comes on, then to each city comes a boat from that which is called the island of Prosopitis (this is in the Delta, and the extent of its circuit is nine schoines).  In this island of Prosopitis is situated, besides many other cities, that one from which the boats come to take up the bones of the oxen, and the name of the city is Atarbechis, and in it there is set up a holy temple of Aphrodite.  From this city many go abroad in various directions, some to one city and others to another, and when they have dug up the bones of the oxen they carry them off, and coming together they bury them in one single place.  In the same manner as they bury the oxen they bury also their other cattle when they die; for about them also they have the same law laid down, and these also they abstain from killing.

Now all who have a temple set up to the Theban Zeus or who are of the district of Thebes, these, I say, all sacrifice goats and abstain from sheep:  for not all the Egyptians equally reverence the same gods, except only Isis and Osiris (who they say is Dionysos), these they all reverence alike:  but they who have a temple of Mendes or belong to the Mendesian district, these abstain from goats and sacrifice sheep.  Now the men of Thebes and those who after their example abstain from sheep, say that this custom was established among them for the cause which follows:—­Heracles (they say) had an earnest desire to see Zeus, and Zeus did not desire to be seen of him; and at last when Heracles was urgent in entreaty Zeus contrived this device, that is to say, he flayed a ram and held in front of him the head of the ram which he had cut off, and he put on over him the fleece and then showed himself to him.  Hence the Egyptians make the image of Zeus with the face of a ram; and the Ammonians do so also after their example, being settlers both
