Fates in Greek and Roman mythology are any of three goddesses who determined human destinies and in particular the span of a person’s life and his allotment of misery and suffering. From the time of the poet Hesiod (8th century BC) the Fates were personified as three very old women who spin the threads of human destiny. Their names were Clotho (Spinner) Lachesis (Allotter) and Atropos (Inflexible). Clotho spun the “thread” of human fate Lachesis dispensed it and Atropos cut the thread (thus determining the individual’s moment of death). The Romans identified the Parcae originally personifications of childbirth with the three Greek Fates. The Roman goddesses were named Nona Decuma and Morta.
