Tartarus

In classic mythology, below Uranus, Gaia, and Pontus is Tartarus, or Tartaros (Greek Τάρταρος, deep place). It is a deep, gloomy place, a pit, or an abyss used as a dungeon of torment and suffering that resides beneath the underworld. In the Gorgias, Plato (c. 400 BC) wrote that souls were judged after death and those who received punishment were sent to Tartarus. As a place of punishment, it can be considered a hell. The classic Hades, on the other hand, is more similar to Old Testament Sheol.
