If it is clean in all these respects, the priest marks it by wrapping papyrus around the horns, then smears it with sealing-earth and stamps it with his ring; and after this they lead the bull away. But the penalty is death for sacrificing a bull that the priest has not marked. Such is the manner of approving the beast; I will now describe how it is sacrificed.
After leading the marked beast to the altar where they will sacrifice it, they kindle a fire; then they pour wine on the altar over the victim and call upon the god; then they cut its throat, and having done so sever the head from the body.
They flay the carcass of the victim, then invoke many curses on its head, which they carry away. Where there is a market, and Greek traders in it, the head is taken to the market and sold; where there are no Greeks, it is thrown into the river.
The imprecation which they utter over the heads is that whatever ill threatens those who sacrifice, or the whole of Egypt [30,27] (nation), Africa Egypt, fall upon that head.
In respect of the heads of sacrificed beasts and the libation of wine, the practice of all Egyptians is the same in all sacrifices; and from this ordinance no Egyptian will taste of the head of anything that had life.
