Adrastus (he who stands his ground) In Greek mythology, a king of Argos; son of Talaus and Lysimache (or Eurynome or Lysianassa); married to Amphithea; father of Argeia, Aegialeia, Aegialeus, Cyanippus, Deipyle, and Hippodameia. Adrastus led the “Seven against Thebes” in an ill-fated expedition to restore Polynices, son of Oedipus, to the throne of Thebes. In a fight between the three ruling houses in Argos—the Biantidae, Melampodidae, and Proetidae—Adrastus was driven out by Amphiaraus. Adrastus fled to his maternal grandfather, King Polybus of Cicyoun, and later inherited his kingdom. Adrastus was reconciled to Amphiaraus, to whom he gave his sister Eriphyle. He later returned and ruled over Argos, where one stormy night a great scuffle was heard outside the palace. Two fugitives, Polynices and Tydeus (one wrapped in a lion’s skin, the other in a boar’s skin), had sought refuge in the front court and were fighting for a night’s lodging. Adrastus recognized this as the fulfillment of an oracle that had told him to marry his daughters to a lion and a boar. Adrastus gave his daughter Argeia to Polynices and Deipyle to Tydeus. He promised to conduct the two exiles to Thebes and install Polynices on the throne. This is the subject of Aeschylus’s play Seven Against Thebes. In the ensuing war only Adrastus escaped destruction by fleeing on his winged horse Arion. Ten years later, with the sons (called the Epigoni) of the slain warriors of this ill-fated expedition and his son Aegialeus, Adrastus marched on Thebes.
He took the city but lost his son and died of grief on his way home.
