Pausanias Description of Greece 2.2.3

[3]
  The names of the Corinthian harbors were given them by Leches and Cenchrias, said to be the children of Poseidon and Peirene the daughter of Achelous, though in the poem called The Great Eoeae ¹ Peirene is said to be a daughter of Oebalus. In Lechaeum are a sanctuary and a bronze image of Poseidon, and on the road leading from the Isthmus to Cenchreae a temple and ancient wooden image of Artemis. In Cenchreae are a temple and a stone statue of Aphrodite, after it on the mole running into the sea a bronze image of Poseidon, and at the other end of the harbor sanctuaries of Asclepius and of Isis. Right opposite Cenchreae is Helen's Bath. It is a large stream of salt, tepid water, flowing from a rock into the sea.
