The underlying message of the myth of Sisyphus revolves around the themes of existential struggle and the futility of life’s endeavors. Sisyphus was condemned to roll a boulder up a hill only to have it roll back down for eternity. This endless task serves as a metaphor for human existence, illustrating the absurdity of certain pursuits. Albert Camus later interpreted Sisyphus as a symbol of resilience, suggesting that finding meaning in our struggles, even in absurdity, is a fundamental aspect of the human condition.
