who has to push the rock up the hill
Sisyphus In Greek mythology Sisyphus or Sisyphos (/ˈsɪsɪfəs/;[2] 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 for it to roll down when it nears 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 (/ˌsɪsɪˈfiːən/).
