Callirrhoë (fair flowing) In Greek mythology, daughter of the river god Achelous; sister of Castalia and Peirene; unwittingly sent her husband Alcmaeon to his death by persuading him to obtain Harmonia’s necklace and robe from Alphesiboea. When Alphesiboea’s brothers discovered the attempt, they murdered him. Callirrhoë is also the name of a daughter of Oceanus and Tethys and the mother of the three-headed cowherd Geryon, Cerberus, and Echidna, according to some accounts. The name is also that of a daughter of the Trojan river god Scamander; she was married to Tros and mother of Assaracus, Cleopatra, Ilus, and Ganymede. She killed herself, and a fountain in Attica is named after her.
