known in English as the Fatesโwere the personifications of destiny. They were three sisters: Clotho (the spinner), Lachesis (the allotter), and Atropos (the inevitable, a metaphor for death). The role of the Moirai was to ensure that every being, mortal and divine, lived out their destiny as it was assigned to them by the laws of the universe.
