On proposing the expedition to the Argeian chiefs around him he found most of them willing auxiliaries; but Amphiaräus—formerly his bitter opponent, but now reconciled to him, and husband of his sister Eriphylê—strongly opposed him.[646] He denounced the enterprise as unjust and contrary to the will of the gods. Again, being of a prophetic stock, descended from Melampus, he foretold the certain death both of himself and of the principal leaders, should they involve themselves as accomplices in the mad violence of Tydeus or the criminal ambition of Polynikês. Amphiaräus, already distinguished both in the Kalydônian boar-hunt and in the funeral games of Pelias, was in the Thêban war the most conspicuous of all the heroes, and absolutely indispensable to its success. But his reluctance to engage in it was invincible, nor was it possible to prevail upon him except through the influence of his wife Eriphylê. Polynikês, having brought with him from Thêbes the splendid robe and necklace given by the gods to Harmonia on her marriage with Kadmus, offered it as a bribe to Eriphylê, on condition that she would influence the determination of Amphiaräus. The sordid wife, seduced by so matchless a present, betrayed the lurking-place of her husband, and involved him in the fatal expedition.[647] Amphiaräus, reluctantly dragged forth, and foreknowing the disastrous issue of the expedition both to himself and to his associates, addressed his last injunctions, at the moment of mounting his chariot, to his sons Alkmæôn and Amphilochus, commanding Alkmæôn to avenge his approaching death by killing the venal Eriphylê, and by undertaking a second expedition against Thêbes.

The treachery of “the hateful Eriphylê” is noticed in the Odyssey, xi. 327: Odysseus sees her in the under-world along with the many wives and daughters of the heroes.
