(from βυξ ox, and σφαγή slaughter), in antiquity, an Athenian feast or ceremony, denominated from a bullock slain therein, with quaint formalities. For the origin of the buphonia, we are told it was forbidden by the laws of Attica to kill an ox: but it once happened, at the feast of the dipolia, that an ox eat the corn, others say the cakes, which had been dressed for the sacrifice. Thaulon the priest, enraged at this, presently killed him, and fled for it. On which the Athenians, fearing the resentment of the gods, and feigning themselves ignorant who had com- mitted the fact, brought the bloody axe before the judges, where it was solemnly arraigned, tried, found guilty, and condemned. And, in memory of this event, a feast was instituted under the denomination of buphonia. In which it was still customary for the priest to fly, and judgment to be given about the slaughter of the ox.
