The three Fates in Greek mythology, known as the Moirae, are Clotho, Lachesis, and Atropos. Clotho spins the thread of life, Lachesis measures its length, and Atropos cuts it, determining the moment of death. Together, they represent the inescapable nature of fate and the belief that no one can alter their preordained destiny. Their influence underscores themes of inevitability and the human struggle against fate within Greek narratives.
