[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.
