41. 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 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 of 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 45 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.
