Deiphontes
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.
When Temenus, in the division of Peloponnesus, had obtained Argos as his share, he bestowed all his affections upon Hyrnetho and her husband, for which he was murdered by his sons, who thought themselves neglected. But after the death of Temenus, the army declared Deiphontes and Hyrnetho his rightful successors. ( The Theogony of Apollodorus II)
According to Pausanias ( Description of Greece by Pausanias Book 2), the sons of Temenus formed indeed a conspiracy against their father and Deiphontes; but after Temenus's death it was not Deiphontes that succeded him, but Ceisus. Deiphontes. on the other hand, is said to have lived at Epidaurus, whither he went with the army which was attached to him, and from whence he expelled the Ionian king, Pityreus. (Pais. ii. 26. § 2.)
His brothers-in-law, however, who grudged him the possession of their sister Hyrnetho, went to Epidaurus, and tried to persuade her to leave her husband; and when this attempt failed, they carried her off by force. Deiphontes pursued them, and after having killed one of them, Cerynes, he wrestled with the other, who held his sister in his arms. In this struggle, Hyrnetho was killed by her own brother, who then escaped. Deiphontes carried her body back to Epidaurus, and there erected a sanctuary to her. (Paus. ii. 28. § 3.)
From Smith's Dictionary of Greek and Roman Biography and MythologyFrom Description of Greece by Pausanias Book 2
[2.26.1] At Lessa the Argive territory joins that of Epidaurus. But before you reach Epidaurus itself you will come to the sanctuary of Asclepius. Who dwelt in this land before Epidaurus came to it I do not know, nor could I discover from the natives the descendants of Epidaurus either. But the last king before the Dorians arrived in the Peloponnesus was, they say, Pityreus, a descendant of Ion, son of Xuthus, and they relate that he handed over the land to Deiphontes and the Argives without a struggle.
[2.28.6] Realizing what he had done to his sister, he began to drive the chariot more recklessly, as he was anxious to gain a start before all the Epidaurians could gather against him. Deiphontes and his children--for before this children had been born to him, Antimenes, Xanthippus, and Argeus, and a daughter, Orsobia, who, they say, after-wards married Pamphylus, son of Aegimius--took up the dead body of Hyrnetho and carried it to this place, which in course of time was named Hyrnethium.
From The Theogony of Apollodorus II
Now Temenus, passing over his sons Agelaus, Eurypylus, and Callias, favoured his daughter Hyrnetho and her husband Deiphontes; hence his sons hired some fellows to murder their father. On the perpetration of the murder the army decided that the kingdom belonged to Hyrnetho and Deiphontes.
