Sparagmos

Sparagmos (Ancient Greek: σπαραγμός, from σπαράσσω sparasso, "tear, rend, pull to pieces") is an act of rending, tearing apart, or mangling, usually in a Dionysian context.
In Dionysian rite as represented in myth and literature, a living animal, or sometimes even a human being, is sacrificed by being dismembered. Sparagmos was frequently followed by omophagia (the eating of the raw flesh of the one dismembered). It is associated with the Maenads or Bacchantes, followers of Dionysus, and the Dionysian Mysteries. Historically, however, there is little indication that women celebrating the rites of Dionysius dismembered animals or ate raw flesh.
