Hecatomb

[2] Hecatombs were offered to Greek gods Hera, Athena, and Apollo during special religious ceremonies.

The following is one instance, from Samuel Butler's translation: [T]hey arranged the holy hecatomb all orderly round the altar of the god.

They cut out the thigh-bones, wrapped them round in two layers of fat, set some pieces of raw meat on the top of them, and then [the priest] laid them on the wood fire and poured wine over them, while the young men stood near him with five-pronged spits in their hands.

When the thigh-bones were burned and they had tasted the inward meats, they cut the rest up small, put the pieces upon the spits, roasted them till they were done, and drew them off: then, when they had finished their work and the feast was ready, they ate it, and every man had his full share, so that all were satisfied.

As soon as they had had enough to eat and drink, pages filled the mixing-bowls with wine and water and handed it round, after giving every man his drink-offering.
