In Greek mythology, Cisus, (or Ceisus), son of Temenus, was a king of Argos.
Temenus had initially left his kingdom to his son in law, Deiphontes, despite having natural sons of his own. As a result, Deiphontes was slain through the stratagems of the sons of Temenus. The eldest son, Cisus, succeeded him and took possession of the kingdom.
In Greek mythology, Temenus /ˈtɛmɪnəs/ (Greek: Τήμενος, Tḗmenos) was a son of Aristomachus and brother of Cresphontes and Aristodemus.
Temenus was a great-great-grandson of Heracles and helped lead the fifth and final attack on Mycenae in the Peloponnese. He became King of Argos. He was the father of Ceisus, Káranos, Phalces (who was said to be founder of Sicyon), Agraeus, and Hyrnetho. Káranos was the first king of the ancient Greek kingdom of Macedonia and founder of the royal Macedonian dynasty–the Temenid or Argead dynasty–which culminated in the sons of Alexander the Great five centuries later.
In Greek mythology, Hyrnetho (Ancient Greek: Ὑρνηθώ, romanized: Hurnēthṓ) was a daughter of Temenus, and the wife of Deiphontes, by whom she became mother of Antimenes, Xanthippus, Argeius, and Orsobia.
Temenus favored his daughter Hyrnetho and her husband Deiphontes more than his sons, Hyrnetho's brothers, and planned on making Deiphontes his heir. His sons plotted against him and killed him, but nevertheless, the kingdom of Argos passed to Deiphontes and Hyrnetho, since the army supported them rather than Temenus' sons; alternately, the kingdom was seized by Ceisus, the eldest son of Temenus.
