sisyphesque

From the name of Sisyphus (from Ancient Greek σίσυφος, sísyphos), the mythological son of Aeolus, son of Hellen and Enarete, founder of Corinth, reputed to be the most cunning of men. For daring to defy the gods, Sisyphus was condemned to eternally roll a stone up a hill, which would roll back down just before reaching the top.
