Distant from Argos forty stades and no more is the sea at Lerna. On the way down to Lerna the first thing on the road is the Erasinus, which empties itself into the Phrixus, and the Phrixus into the sea between Temenium and Lerna. About eight stades to the left from the Erasinus is a sanctuary of the Lords Dioscuri (Sons of Zeus). Their wooden images have been made similar to those in the city.

On returning to the straight road, you will cross the Erasinus and reach the river Cheimarrus (Winter-torrent). Near it is a circuit of stones, and they say that Pluto, after carrying off, according to the story, Core, the daughter of Demeter, descended here to his fabled kingdom underground. Lerna is, I have already stated, by the sea, and here they celebrate mysteries in honor of Lernaean Demeter.
