Iphimedeia

Means "ruling over with strength" from Greek ἶφι (iphi) "strongly, stoutly, mightily, by force" (compare the first element in Iphianassa, Iphigeneia, Iphidamas and Iphiklos) and the verbal root μέδ- (med-) from μεδω (medo) "to protect, to rule over" with the feminine noun suffix -εια (-eia). In Greek myth Iphimedeia was a Thessalian princess, the daughter of King Triopas (a son of Poseidon and Canace). She fell in love with Poseidon and bore him children including Otus and Ephialtes (who were called the Aloadae after their stepfather), as well as Cercyon and the bandit Sciron. She was one of the heroines whose spirits Odysseus encountered at the entrance of the Underworld.
