Astydameia was the mother of Ktesippus by Heracles. In one source, she is the daughter of Amyntor and Cleobule. Another account makes her the daughter of Ormenius, king of Pelasgiotis. Heracles, the same source relates, wooed her, but Ormenius would not marry her to him since Heracles was already married to Deianira. Heracles then led a war against Ormenius, killed him and took Astydameia by force.
