In addition to the Spring (or Fountain) of Peirene, Corinth had another significant water supply — the Fountain of Glauke. Reddish and Fant describe the fountain:
To the west of the temple [of Apollo] and on a lower level lies the Fountain of Glauke, supplied with water by a conduit from the Acrocorinth, virtually nothing of which remains except four reservoirs cut in the rock. It was named for the legendary daughter of a king of Corinth who threw herself into its waters to escape the flames of the magical robe sent her by Medea. Originally the fountain was covered by a building approximately 45 feet long and 40 feet wide. (A Guide to Biblical Sites in Greece and Turkey, 59).
Among the Christians at Corinth during the time of the Apostle Paul, we can certainly imagine that some of them visited these sites we have learned about as a result of the archaeological excavations over the past century. See Acts 18; 1 Corinthians; 2 Corinthians.
