Zeuxippe was a Naiad. She married her nephew Pandion, king of Athens, and bore him twin sons, Erechtheus and Butes, and twin daughters, Procne and Philomela. Her name may be simply propitious, since it means 'she who yokes horses', from zeugos, 'yoke of beasts', 'pair of horses' and hippos, 'horse'. (Greek zeugos and English 'yoke' are related words.) But could not this 'pair of horses' actually refer to her two sets of twins?
