In Greek mythology, Olynthus (Ancient Greek: Ὄλυνθος) 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.[1] According to Conon[2] and Stephanus of Byzantium,[3] Olynthus was son of king Strymon, and brother of Brangas and Rhesus.[2]
