In Greek mythology, Sisyphus or Sisyphos was the founder and king of Ephyra (now known as Corinth). He was a devious tyrant who killed visitors to show off his power. This violation of the sacred hospitality tradition greatly angered the gods. They punished him for trickery of others, including his cheating death twice. The gods forced him to roll an immense boulder up a hill only for it to roll back 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 (/sɪsɪˈfiːən/).
