In Greek mythology, Astydamia (/əˌstɪdəˈmiːə/; Ancient Greek: Ἀστυδάμεια, romanized: Astudámeia, lit. 'tamer of the city'), also called Hippolyta and sometimes simply identified as Cretheis in a patronymic manner (Κρηθηίς, meaning “the daughter of Cretheus”), is a princess and then queen of the ancient Greek city of Iolcus in Thessaly, the daughter of Cretheus and wife of Acastus. Astydamia fell in love with Peleus of Phthia and tried to seduce him during his short stay at Iolcus, but when her efforts failed she accused him of assault to her husband Acastus, an act that would make Peleus forever an enemy to the royal couple and their city.
