According to the Greek myth, Sisyphus or Sisyphos was the king of Ephyra (now known as Corinth).

Sisyphus is condemned to roll a rock up to the top of a mountain, only to have the rock roll back down to the bottom every time he reaches the top.

Sisyphus was the son of King Aeolus of Thessaly and Enarete. He was the father of Glaucus, Ornytion, Almus, and Thersander by the nymph Merope, the brother of Salmoneus, and the grandfather of Bellerophon through Glaucus.
