As punishment, Sisyphus was condemned to push a huge boulder up a hill forever, only for it to roll back down each time.

The gods made Sisyphus’s punishment eternal and pointless. Every time he pushed the boulder close to the top of the hill, it would slip from his hands and fall back to the bottom. This meant he had to start all over again, making his task endless and frustrating. This story became a symbol of a never-ending, futile struggle.
