“Swine are held by the Egyptians to be unclean beasts. In the first place, if an Egyptian touches a hog in passing, he goes to the river and dips himself in it, clothed as he is; and in the second place, swineherds, though native born Egyptians, are alone of all men forbidden to enter any Egyptian temple; nor will any give a swineherd his daughter in marriage, nor take a wife from their women; but swineherds intermarry among themselves. [2] Nor do the Egyptians think it right to sacrifice swine to any god except the Moon and Dionysus; to these, they sacrifice their swine at the same time, in the same season of full moon; then they eat the meat. The Egyptians have an explanation of why they sacrifice swine at this festival, yet abominate them at others; I know it, but it is not fitting that I relate it. [3] But this is how they sacrifice swine to the Moon: the sacrificer lays the end of the tail and the spleen and the caul together and covers them up with all the fat that he finds around the belly, then consigns it all to the fire; as for the rest of the flesh, they eat it at the time of full moon when they sacrifice the victim; but they will not taste it on any other day. Poor men, with but slender means, mold swine out of dough, which they then take and sacrifice. (2:47)”
