The adjective gadarene describes something headlong or precipitate, such as a gadarene rush to pass legislation. It derives from a story in the gospel of Matthew in which Jesus visits the land of the Gadarenes and casts out demons from someone possessed by them. The exorcised demons invade a herd of swine, driving the animals mad, sending them to plunge to their deaths in the Sea of Galilee. From another version of the story in the Book of Mark comes a phrase that may be more familiar: My name is Legion. This is part of a complete episode.
