The king of Elis. He had a enormous stable with 3000 cattle that had not been cleansed in thirty years. Heracles, as one of his Twelve Labors, had to clean the stable in one day. He did so by diverting the rivers Alpheus and Peneus through the stable, which washed the muck and dung away. This displeased Augeas greatly because he had promised Heracles one-tenth of his herd should he complete the task in one day. He refused to honor the agreement and fought with Heracles, but got killed instead.
