Themisto

In Greek mythology, Themisto (; ) was a Thessalian princess as the daughter of King Hypseus of Lapiths and the naiad Chlidanope. Her name is derived from the Ancient Greek word: "θεμιστος" which means "belonging to the law", or "belonging to the customs".

== Family == Themisto's sisters were Cyrene, Alcaea and Astyagyia. She was the third and last wife of Athamas, a Boeotian king. According to some sources, the couple had four children: Leucon, Erythrius, Schoeneus, and Ptous. In other sources, there were but two: Sphincius and Orchomenus, or else Schoeneus and Leucon. Some say that the father of Leucon was Poseidon (see also Leuconoe).
