Hell in Greek mythology. It was part of Hades, the underworld and the worst people were sent their to be tormented.

For instance, one fellow was kept neck deep in a river but if he tried to drink the water sank away, leaving him with an everlong thirst. Another was forced to push a boulder up a hill. If he got to the top he could go the the Elysian Fields, but near the top, the boulder split and he had to start over.
