Sisyphus was a man out of Greek legends infamous for being evil and treacherous. He was rumored to attack travelers. He also gave away the secrets of the gods and even captured the god of death, Thanatos, and held him prisoner, so that no one who died could get to the underworld. Sisyphus was punished by the gods by being compelled to roll a huge stone up a steep hill; the stone always rolled back down as soon as he reached the top. He was doomed to repeat this process over and over again for eternity.
