In Greek mythology Sisyphus (/ˈsɪsᵻfəs/; Greek: Σίσυφος, Sísuphos) was the king of Ephyra (now known as Corinth). He was punished for his self-aggrandizing craftiness and deceitfulness by being forced to roll an immense boulder up a hill, only to watch it roll back down, repeating this action for eternity.
