Sisyphus
Sisyphus, in Greek mythology, was the founder and king of Ephyra (Corinth), but a man of notorious cruelty and immorality, as a punishment for which he was condemned, after his death at the hand of Theseus, to roll eternally uphill a huge block of marble, which no sooner reached the top than it rolled down again.
