Lost in Tartarus
In Greek mythology Sisyphus or Sisyphos (/ˈsɪsɪfəs/; Ancient Greek: Σίσυφος Sísyphos) 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 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.
Sand man is an ongoing stop motion animation film project which is loosely besed on sisyphus myth.
