Daughter of Pronax and wife of Adrastus, Amphithea was the mother of the Argive royal children who bound the house to the war of the Seven — Argia, Deipyle, Aegialia, Aegialeus, and Cyanippus.1
Apollodorus gives her parentage and marriage in a single genealogical breath: Adrastus had by Amphithea, daughter of Pronax, three daughters and two sons. Through that brood she stands at the centre of the Argive side of the Theban wars — the marriages of Argia and Deipyle to Polynices and Tydeus, the birth of Thersander and Diomedes in the next generation, and the princes Aegialeus and Cyanippus who carried the Biantid line forward.2
Pausanias knew the family in art. At Delphi he describes Polygnotus' painting of the quarrel between Amphiaraus and Lycurgus son of Pronax, with Adrastus and Tydeus holding them apart — a scene that ties her father Pronax to the very seer who would march and vanish among the Seven.3
