Megapenthes (son of Proetus) explained

In Greek mythology, Megapenthes (; Ancient Greek: Μεγαπένθης Megapénthēs means "great sorrow") was a king of Argos.

Family

Megapenthes was the son and successor of Proetus^[1] and father of either Argeus^[2] or Anaxagoras (in some accounts, Anaxagoras was his grandson through Argeus). He also had a daughter Iphianeira, who married Melampus.^[3]

Megapenthes exchanged kingdoms (Argos for Tiryns) with his cousin Perseus^[4] whom he killed much later.^[5]
