In Greek mythology, Automedusa (Ancient Greek: Αὐτομεδούση or Αὐτομέδουσα) was a Megarian princess as the daughter of King Alcathous either by his first wife, Pyrgo or second spouse, Evaechme, daughter of King Megareus of Megara.[1] Thus, she was the sister of Ischepolis,[2] Callipolis,[3] Iphinoe[1] and Periboea.[4] Automedusa married Heracles's half-brother Iphicles and had by him a son Iolaus, who became the charioteer of Heracles.[5]
