In Greek mythology, Olynthus was a son of Heracles and Bolbe, from whom the ancient city of Olynthus, and the river Olynthus near Apollonia, were believed to have received their name according to Athenaeus. According to Conon and Stephanus of Byzantium Olynthus was son of king Strymon. When he had been killed during the chase by a lion, his brother Brangas buried him on the spot where he had fallen, and called the town which he subsequently built there Olynthus.
