Lysippe was the daughter of
Proëtus and
Stheneboea. She was cured of her madness by
Melampus and married him, bearing him Abas, Mantius and Antiphater. Her name means '
horse releaser', which could be taken to be a 'powerful' name (for one who has power over horses), or else a 'chaotic' name (for one who loses control). If the latter, this could be a reference to Lysippe's madness. The two halves of her name are luo, 'to release' and hippos, 'horse', 'mare'.
