In Greek mythology, the main role of the Fates is to control the destiny of all beings, including gods and mortals. Composed of three sisters—Clotho (the spinner), Lachesis (the allotter), and Atropos (the unchangeable)—they weave, measure, and cut the thread of life. The Fates underscore the theme of inevitability and the limitations of free will, symbolizing the belief that a predetermined plan governs existence. Their influence emphasizes the interconnectedness of actions and fates across the human experience.
