All Egyptians sacrifice unblemished bulls and bull-calves; they may not sacrifice cows: these are sacred to Isis.

For the images of Isis are in woman's form, horned like a cow, exactly as the Greeks picture Io, and cows are held by far the most sacred of all beasts of the herd by all Egyptians alike.

For this reason, no Egyptian man or woman will kiss a Greek man, or use a knife, or a spit, or a cauldron belonging to a Greek, or taste the flesh of an unblemished bull that has been cut up with a Greek knife.

Cattle that die are dealt with in the following way. Cows are cast into the river, bulls are buried by each city in its suburbs, with one or both horns uncovered for a sign; then, when the carcass is decomposed, and the time appointed is at hand, a boat comes to each city from the island called Prosopitis,

an island in the Delta, nine schoeni in circumference. There are many other towns on Prosopitis; the one from which the boats come to gather the bones of the bulls is called Atarbekhis;No doubt from Athor or Hathor, under which name Isis was often worshipped. a temple of Aphrodite stands in it of great sanctity.

From this town many go out, some to one town and some to another, to dig up the bones, which they then carry away and all bury in one place. As they bury the cattle, so do they all other beasts at death. Such is their ordinance respecting these also; for they, too, may not be killed.
