"Fair-flowing." A daughter of Achelous and the second wife of Alcmaeon, whom she induced to procure her the peplus and necklace of Harmonia, by which she caused her husband's death. Callirrhoe then requested Zeus, with whom she lived in close intimacy, to grant that her sons by Alcmaeon might grow up to manhood at once, in order that they might be able to avenge the death of their father. Zeus granted the request, and Amphoterus and Acarnan killed the murderers of their father, the sons of Phegeus, at Delphi, and afterwards Phegeus himself also.
