Singular the Parcae in Roman mythology, the Moirae in Greek and the Norns in the Nordic. They are the goddesses of destiny, personifications of the fatum, which control the thread of life from birth to death. Three sisters spinners: Nona, tenth and Morta in latin. In Greek, Clotho, the youngest, spinning the threads of life with her spinning-wheel, Lachesis decided its length and Atropos, the mayor, also called Aisa, cut them with their inexorable scissors.
