The Fates, known as the Moirae in Greek mythology, are three goddesses: Clotho, who spins the thread of life; Lachesis, who measures its length; and Atropos, who cuts it at its death. They symbolize the inevitability of fate and destiny, controlling the life and lifespan of every individual. Their power is absolute, and even the gods cannot alter the fate they decree, emphasizing the ancient Greek belief in the predestined nature of life.
