Argeius (Ancient Greek: Ἀργεῖος, but also sometimes Argeus) was one of the Elean deputies sent to the Persian Empire to co-operate with Pelopidas in 367 BCE on counteracting Spartan negotiation and attaching Artaxerxes II of Persia to the Theban cause.
He is again mentioned by the writer Xenophon, in his account of the war between the Arcadians and Eleans in 365 , as one of the leaders of the democratic party at Elis.
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.
Deiphontes (/diː.ɪˈfɒntiːz/; Ancient Greek: Δηϊφόντης) was king of Argos. He was a son of Antimachus, and husband of Hyrnetho, the daughter of Temenus the Heracleide, by whom he became the father of Antimenes, Xanthippus, Argeius, and Orsobia. Deiphontes was descended from Ctesippus, the son of Heracles by Deianira.
