Sisyphus & Tantalus
The gods had condemned Sisyphus to ceaselessly rolling a rock to the top of a mountain, whence the stone would fall back of its own weight. They had thought with some reason that there is no more dreadful punishment than fu tile and hopeless labor.

Tantalus was the son of Zeus and was the king of Sipylos. He was uniquely favored among mortals since he was invited to share the food of the gods. However, he abused the guest-host relationship and was punished by being "tantalized" with hunger and thirst in Tartarus: he was immersed up to his neck in water, but when he bent to drink, it all drained away; luscious fruit hung on trees above him, but when he reached for it the winds blew the branches beyond his reach.
