Histories

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.

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.

To Dionysus, on the evening of his festival, everyone offers a piglet which he kills before his door and then gives to the swineherd who has sold it, for him to take away.

The rest of the festival of Dionysus is observed by the Egyptians much as it is by the Greeks, except for the dances; but in place of the phallus, they have invented the use of puppets two feet high moved by strings, the male member nodding and nearly as big as the rest of the body, which are carried about the villages by women; a flute-player goes ahead, the women follow behind singing of Dionysus.

Why the male member is so large and is the only part of the body that moves, there is a sacred legend that explains.
