Who is Sisyphus from The Myth of Sisyphus and Other Essays and what is their importance?

Sisyphus is a character from Greek mythology who Camus believes represents the absurd man. Sisyphus rejected the gods in favor of earthly goods and his punishment was to continually roll a rock up a hill, after which it would roll back down the bottom. Sisyphus is an absurd man because he rejects the eternal and divine in favor of the present and earthly and because his existence is obviously meaningless—nothing could be more clearly without meaning than pointlessly pushing a rock up a hill for eternity. However, despite this punishment, Camus sees Sisyphus as ultimately free and happy, because he rejects any attempt to find meaning in his life and is content simply with experiencing.
