Sisyphus was sentenced by the gods to roll that rock up the hill for all eternity only to see it roll back down. So, was he condemned to a life in vain because no effort on his part could ever get that rock over the top? I think he eventually replaced that impossible goal with a different one: the sport (or the art?) of playfully testing the limits of a prison he knew he could never escape. By redefining his task, he made his condemnation work for him: he suffused it with form and meaning.
