Antheleia was one of the fifty Danaids (Daughters of Danaus) who took part in the mass marriage to the sons of Aigyptos (Danaus' twin brother). Antheleia married Kisseus whose mother Kaliadne happened to be the sister of Polyxo (Antheleia's mother) this made the relations between Anthelia and her husband even more incestuous. The night of the marriage Antheleia along with all but one of the daughters of Danaus slew their husbands.
Danaus & Polyxo
Spouse & Lovers
When Anthelia 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. Anthelia 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.
"The twelve sons of a Naias Nymph named Kaliadne [and Aigyptos]drew lots for the daughters of Polyxo, also a Naias [and Danaus]. The sons were named Eurylokhos, Phantes, Peristhenes, Hermos, Dryas, Potamon, Kisseus, Lixos, Imbros, Bromios, Polyktor, and Khthonios; the girls were Autonoe, Theano, Elektra, Kleopatra, Eurydike, Glaukippe, Antheleia, Kleodore, Euippe, Erato, Stygne, and Bryke."
