Porthaon
In Greek mythology, Porthaon (Ancient Greek: Πορθάων, genitive Πορθάονος), sometimes referred to as Parthaon or Portheus (seems related to the verb portheō and perthō, "destroy'), was a king of Calydon and son of Agenor or Ares by Epicaste and thus brother of Demonice (also known as Demodice) and possibly Thestius.
