The Fates, known as the Moirai in Greek mythology, control the destinies of both gods and mortals. They include Clotho, who spins the thread of life, Lachesis, who measures its length, and Atropos, who cuts the thread, marking the end of life. This triad emphasizes the belief that fate is inescapable and predetermined, shaping the actions and lives of individuals. Their influence highlights the significance of destiny in Greek thought and the limited power of even the gods when confronted with the laws of fate.
