The primary focus of the Myth of Sisyphus is the concept of eternal struggle and the human condition. Sisyphus, condemned to roll a boulder up a hill only for it to roll back down, represents the futility of certain human endeavors. This allegorical tale, famously interpreted by philosopher Albert Camus, explores themes of absurdism and the meaning of life despite its inherent struggles. Ultimately, Sisyphus becomes a symbol of resilience, demonstrating that embracing the absurd and continuing to strive can provide a sense of purpose.
