Under Greek influence, he was identified with Hippolytus, who after he had been trampled to death by the horses of Poseidon was restored to life by Asclepius and removed by Artemis to the grove at Aricia, which horses were not allowed to enter.
The cella of the temple of Heracles underwent considerable modifications in Roman times, and the discovery in it of a statue of Asclepius seems to show that the cult of this deity superseded the original one.
Of that of Hephaestus only two columns remain, while of that of Asclepius, a mile to the south of the town, an anta and two pillars are preserved.
Leake, whom Frazer follows, assumed the Pelasgicum to be a fortified space at the western end of the Acropolis; this view necessitates the assumption that the nine gates were built one within the other, but early antiquity furnishes no instance of such a construction; DOrpfeld believes it to have extended from the grotto of Pan to the sacred precinct of Asclepius.
Another enclosure, a little to the south, is proved by an inscription to have been a sanctuary of the hitherto unknown hero Amynos, with whose cult those of Asclepius and the hero Dexion were here associated; under the name Dexion, the poet Sophocles is said to have been worshipped after his death.
