Klotho was one of the Three Fates, sisters who determined the destinies of gods and men. Klotho worked a great spindle from which she spun the thread of life, and was known as “the Weaver.” She was associated with births and beginnings, and had the power to return to life those which she deemed had died before their time. Her role in the tale of Alcestis and Admetos is pivotal.
Alcestis was the wife of King Admetus of Pherae, in Thessaly. When he became ill and died, Alcestis mourned him incessantly, until at last she appealed to the Fates to restore him. Alcestis plied Klotho with wine, until she revealed that Admetus could be released from the underworld if someone were found to take his place. As no one offered to help, Alcestis herself made the sacrifice, sinking toward death as Admetus returned to life. But Heracles visited the palace just as Death came for Alcestis; the hero wrestled with Death and forced him to release Alcestis, who was reunited with her husband.
Astrologically, Klotho represents beginnings, the origins of things, and circumstances as matters are initiated; expectations of normal development; and preliminary conditions or understanding.
