Overview
In Greek mythology, Amphiaraus or Amphiaraos (; Ancient Greek: Ἀμφιάραος, Ἀμφιάρεως, "very sacred") was the son of Oicles, a seer, and one of the leaders of the Seven against Thebes. Amphiaraus at first refused to go with Adrastus on this expedition against Thebes as he foresaw the death of everyone who joined the expedition. His wife, Eriphyle, eventually compelled him to go.
Family
Amphiaraus was the son of Oicles. This made Amphiaraus a great-grandson of Melampus, himself a legendary seer, and a member of one of the most powerful dynastic families in the Argolid. The mythographer Hyginus says that Amphiaraus's mother was Hypermnestra, the daughter of Thestius. She was the sister of Leda, the queen of Sparta who was the mother of Helen of Troy, Clytemnestra, and the Dioscuri (Castor and Pollux). Hyginus also reports that "some authors" said that Amphiaraus was the son of Apollo.
Amphiaraus married Eriphyle, the sister of his cousin Adrastus (the grandson of Melampus' brother Bias), and by her was the father of two sons, Alcmaeon and Amphilochus. From the geographer Pausanias, we hear of three daughters, Eurydice, Demonissa and Alcmena.
He reports seeing on the Chest of Kypselos at Olympia, a scene showing Amphiararaus' departure for the expedition against Thebes. Pausanias identifies (possible from inscriptions) other participants in the scene as: the infant Amphilochus, Eryphyle, her daughters, Eurydice and Demonissa, and a naked Alcmaeon. He goes on to add that the poet Asius also has Alcmena as a daughter of Amphiaraus and Eriphyle. According to Plutarch, Alexida was a daughter of Amphiaraus.
The Clytidae (alternate spelling "Klytidiai"), a clan of seers at Olympia, claimed to be the descendants of a Clytius, who they said was the son of Amphiaraus' son Alcmaeon. According to Roman legends, the founder of the town of Tibur (modern Tivoli) near Rome, was a son of Amphiaraus.
