In Greek mythology, Sisyphus or Sisyphos was the founder and king of Ephyra (now known as Corinth). Zeus punished him for cheating death twice by forcing him to roll an immense boulder up a hill only for it to roll down every time it neared the top, repeating this action for eternity. Through the classical influence on modern culture, tasks that are both laborious and futile are therefore described as Sisyphean.
