Pausanias Description of Greece 2.5.1

[1] As you go up to the summit of the Acrocorinth, there is a shrine [ nāos] of Aphrodite. The statues [ agalmata] there are Aphrodite herself, armed, also Hēlios, also Eros with a bow. The spring [ pēgē], which is behind the shrine [ nāos], they say was the gift of Asopos to Sisyphus, who knew, so they also say, that Zeus had abducted Aegina, the daughter of Asopos, but refused to give information to the seeker before he had some spring-water given him on the Acrocorinth. When Asopos granted this request, Sisyphus turned informer, and because of that he receives—if anyone believes it—punishment in Hādēs. I have heard people say that this spring-water and Peirene are the same, and that the water in the city flows there underground all the way from here.
