Zeus, angered by Sisyphus's actions and defiance, devised a fitting punishment for him in the afterlife. When Sisyphus died, he was condemned to an eternal and futile task. In the depths of the Underworld, he was tasked with rolling a massive boulder up a steep hill. However, just as he neared the summit, the boulder would invariably roll back down, forcing Sisyphus to start over again, repeating this Sisyphean task for all eternity.
