In Greek mythology, Maenalus (Ancient Greek: Μαίναλον or Μαίναλος Mainalos) was an Arcadian prince as one of the 50 sons of the impious King Lycaon[1] either by the naiad Cyllene,[2] Nonacris[3] or by unknown woman. He was the founder of Maenalus which was the most famous of the cities of Arcadia in ancient times.[4]
