Tantalus

The son of Zeus and the father of Pelops and Niobe; his transgressions against the Olympians earned his eternal punishment by Hades (lord of the Underworld) by being placed in a pool of water from which he could never drink and under a fruit tree from which he could never eat.

Tantalus either tried to steal the food of the Immortals or he killed his son, Pelops, and served the flesh to the Olympians; another version of his punishment is given in the fragmentary remains of the Returns; he was permitted to live with the Immortals and allowed to ask for anything he desired; his pleasures were so self-indulgent that Zeus surrounded him with earthly pleasures and placed a giant stone over his head to prevent him from enjoying them.
