Clotho was one of the Three Fates or Moirai in Greek mythology, her sisters being Lachesis and Atropos. She was the one who spun the thread of the lives of all mortals, as well as the one to decide when a person would be born or killed, along with other similarly important decisions. It was also believed that the three sisters and Hermes created the alphabet.
She was the daughter of Zeus and Themis, although some sources mention her mother was Ananke (Necessity). Her Roman equivalent, Nona, was the daughter of Uranus and Gaea. Along with her sisters, Clotho played an important role in Greek myths; she forced Aphrodite to sleep with other gods; she killed the Titan Typhon; she restored Pelops back to life after he was torn to pieces and was cooked by his father Tantalus. She was also fooled by Alcestis, a mortal woman who intoxicated the Fates and told them to save her husband, Admetus, from dying. The Fates agreed but only if someone would take Admetus' place. Alcestis, unable to find anyone else, sacrificed herself.
