In Greek mythology, the Peneus and Alpheus were two rivers re-routed by Heracles in his fifth labour in order to clean the filth from the Augean Stables in a single day, a task which had been presumed to be impossible. A poem by Roger Caillois, called "Le fleuve Alphée" (the Alpheus River), is mainly about this river.
