Anaxibia was one of the fifty Danaids (Daughters of Danaus) who took part in the mass marriage to the sons of Aigyptos. Anaxibia married Archelaus (the son of Aigyptos and a Phoenician woman). That night she along with forty-eight of her forty-nine sisters slew their husbands.
When Anaxibia and the other Danaids who had murdered their husbands they were sent to Tartarus and were forced to carry water from the river Styx in bowls (or jars according to some) with holes over to a tub which leaks at multiple parts. Anaxibia and the others were told only when they filled the tub could they wash away their sins. The Danaids continue this essentially impossible task to this very day.
