Sisyphus
Sisyphus is a figure from Greek mythology who was condemned by the gods to roll a boulder up a hill for eternity, only to watch it roll back down each time he neared the summit. In the Greek telling, his punishment was for tricking Death and chaining Thanatos; the boulder was the instrument of his endless futility. But in Albert Camus's reinterpretation in The Myth of Sisyphus, Sisyphus becomes something more than a cautionary tale: he becomes the archetype of the Absurd hero — the one who persists in an activity the universe has rendered meaningless, and who finds happiness not in success but in the act of rebellion itself. The Sisyphus of Camus is not a victim of fate; he is a strategist of consciousness who has withdrawn his demand that the universe validate his effort.
The Sisyphus figure has become a central symbol in discussions of meaning-making, persistence, and the psychology of repetition without progress. He is the systems-theoretic limit case: a feedback loop with no equilibrium, an attractor that never settles, a process that is its own product.
