TARTARUS

the infernal regions of ancient Greek mythology. The name was originally used for the deepest region of the world, the lower of the two parts of the underworld, where the gods locked up their enemies. It gradually came to mean the entire underworld. As such it was the opposite of Elysium, where happy souls lived after death. In some accounts Tartarus was one of the personified elements of the world, along with Gaea (Earth) and others. According to those accounts, Tartarus and Gaea produced the monster Typhon. Compare Hades.
