The son of Eleios,—or, according to other accounts, of the god Hêlios, of Poseidôn, or of Phorbas,[312]—is Augeas, whom we find mentioned in the Iliad as king of the Epeians or Eleians. Nestôr gives a long and circumstantial narrative of his own exploits at the head of his Pylian countrymen against his neighbors the Epeians and their king Augeas, whom he defeated with great loss, slaying Mulios, the king’s son-in-law, and acquiring a vast booty.[313] Augeas was rich in all sorts of rural wealth, and possessed herds of cattle so numerous, that the dung of the animals accumulated in the stable or cattle enclosures beyond all power of endurance. Eurystheus, as an insult to Hêraklês, imposed upon him the obligation of cleansing this stable: the hero, disdaining to carry off the dung upon his shoulders, turned the course of the river Alpheios through the building, and thus swept the encumbrance away.[314] But Augeas, in spite of so signal a service, refused to Hêraklês the promised reward, though his son Phyleus protested against such treachery, and when he found that he could not induce his father to keep faith, retired in sorrow and wrath to the island of Dulichiôn.[315] To avenge the deceit practised upon him, Hêraklês invaded Elis; but Augeas had powerful auxiliaries, especially his nephews, the two Molionids (sons of Poseidôn by Molionê, the wife of Aktôr), Eurytos and Kteatos. These two miraculous brothers, of transcendent force, grew together,—having one body, but two heads and four arms.[316] Such was their irresistible might, that Hêraklês was defeated and repelled from Elis: but presently the Eleians sent the two Molionid brothers as _Theôri_ (sacred envoys) to the Isthmian games, and Hêraklês, placing himself in ambush at Kleônæ, surprised and killed them as they passed through. For this murderous act the Eleians in vain endeavored to obtain redress both at Corinth and at Argos; which is assigned as the reason for the self-ordained exclusion, prevalent throughout all the historical age, that no Eleian athlête would ever present himself as a competitor at the Isthmian games.[317] The Molionids being thus removed, Hêraklês again invaded Elis, and killed Augeas along with his children,—all except Phyleus, whom he brought over from Dulichiôn, and put in possession of his father’s kingdom. According to the more gentle narrative which Pausanias adopts, Augeas was not killed, but pardoned at the request of Phyleus.[318] He was worshipped as a hero[319] even down to the time of that author.
