Hercules was next sent to Augeas, King of Elis, who had immense droves of cattle.
Augeas had promised him a tenth of the herd, but refused this, alleging that Heracles had acted only in the service of Eurystheus.
Heracles now marched against Augeas to execute his vengeance on him also for his perfidious conduct.
There is still one piece of dirt left in it—and that is a cheating knave, Augeas by name.
Probably the legitimate line of Salmoneus, represented in Augeas.
Augeas did not wait for the decision; he grew angry and commanded his son as well as the stranger to leave his kingdom instantly.
Heracles thereupon sent an army against him, and, though at first defeated, finally slew Augeas and his sons.
But when Augeas heard that this was one of the labours imposed by Eurystheus, he refused the promised guerdon.
Augeas, having broken the bargain, was deposed and slain by Hercules.
But then the stable was that of Augeas, King of Elis, which was at once the largest and the dirtiest in the whole world.
