On the road from Psophis to Thelpusa the first place you come to is on the left of the river Ladon and called Tropæa, and close to it is the oak-coppice called Aphrodisium, and thirdly you come to some ancient writing on a pillar which forms the boundary between the territory of Psophis and Thelpusa. In the district of Thelpusa is a river called Arsen, after crossing which you will come about 25 stades further to the ruins of a village called Caus, and a temple of Causian Æsculapius built by the wayside. Thelpusa is about 40 stades from this temple, and was called they say after the River-Nymph Thelpusa, the daughter of Ladon. The river Ladon has its source, as I have already stated, in the neighbourhood of Clitor, and flows first by Lucasium and Mesoboa and Nasi to Oryx and what is called Halus, and thence to Thaliades and the temple of Eleusinian Demeter close to Thelpusa, which has statues in it no less than 7 feet high of Demeter, Proserpine, and Dionysus, all in stone. And next to this temple of Eleusinian Demeter the river Ladon flows on leaving Thelpusa on the left, which lies on a lofty ridge, and has now few inhabitants, indeed the market-place which is now at the end of the town was originally they say in the very centre. There is also at Thelpusa a temple of Æsculapius, and a temple of the twelve gods mostly in ruins. And after passing Thelpusa the Ladon flows on to the temple of Demeter at Onceum: and the people of Thelpusa call the goddess Erinys, as Antimachus also in his description of the expedition of the Argives to Thebes, in the line, “Where they say was the seat of Demeter Erinys.”
