He is best known for his stables, which housed the single greatest number of cattle in the country and had never been cleaned, until the time of the great hero Heracles.
Augeas's lineage varies in the sources: he was said to be either the son of Helios and Nausidame or of Eleios, king of Elis, and Nausidame, or of Poseidon, or the son of Phorbas and Hyrmine. His children were Epicaste, Phyleus, Agamede (who was the mother of Dictys by Poseidon), Agasthenes, and Eurytus.
Fifth Labour of Heracles
The fifth Labour of Heracles (Hercules in Latin) was to clean the Augean (//) stables. Eurystheus intended this assignment both as humiliating (rather than impressive, like the previous labours) and as impossible, since the livestock were divinely healthy (immortal) and therefore produced an enormous quantity of dung (ἡ ὄνθος). These stables had not been cleaned in over 30 years, and 3,000 cattle lived there. However, Heracles succeeded by rerouting the rivers Alpheus and Peneus to wash out the filth.
Augeas reacted angrily because he had promised Heracles one tenth of his cattle if the job was finished in one day. He refused to honour the agreement, and Heracles killed him after completing the tasks. Heracles gave his kingdom to Phyleus, Augeas' son, who had been exiled for supporting Heracles against his father.
|“||the games which by the ancient tomb of Pelops the mighty Heracles founded, after that he slew Kleatos, Poseidon's godly son, and slew also Eurytos, that he might wrest from tyrannous Augeas against his will reward for service done.||”|
Eurystheus discounted the success of this labour because the rushing waters had done the work of cleaning the stables and because Heracles was paid. Stating that Heracles still had seven labours to do, Eurystheus then sent Heracles to defeat the Stymphalian Birds.
