The stables of Augēas, King of Elis, in Greece. In these stables he had kept 3,000 oxen, and the stalls had not been cleansed for thirty years. When Herculēs was appointed to cleanse these stables, he caused two rivers to run through them.
To cleanse the Augean stables. To clear away an accumulated mass of corruption, moral, religious, physical, or legal. To reform wrongs almost past the power of man to tackle.
