In Greek mythology, Thyraeus (Ancient Greek: Θυραίου or Θυραῖόν means 'at the door') was an Arcadian prince, one of the 50 sons of the impious King Lycaon.^[1] His mother was either the naiad Cyllene,^[2] Nonacris^[3] or an unknown woman. He was the reputed eponymous founder of the Arcadian city of Thyraeum. The Arcadians believed that both Thyrea in Argolis and the Thyrean Gulf were named after Thyraeus.^[4]
