These four towns still existed in the time of Philip of Macedonia, and were well disposed towards Athens, exerting themselves on its behalf, according to their feeble powers, in the Lamian war. Haliae is afterwards no longer mentioned, and the others became members of the Achaean confederacy. The temple of Asclepios, about four miles from the town of Epidaurus, was celebrated as a place to which pilgrimages were undertaken; and in times of distress, this circumstance furnished to the impoverished Epidaurians the means of living. Opposite to Troezen is the island of CALAURIA, where Demosthenes died a free man in the temple of Poseidon, an asylum for all Greece, but which was not respected by the Macedonians. Not far from the coast of the Acte are the islands of TIPARENOS and HYDREA (Speizza and Hydra), which in antiquity were quite insignificant, but have become important in our own age. The latter of them has preserved its name. Hydrea does not even appear to have had a town, but its harbour was used in antiquity.[17] CORINTH is, under this name, not an ancient place; its original name was Ephyra, and the greatness of Corinth belongs to the later or historical period. There is not a single important tradition of the early times that refers to Corinth, and it is quite manifest that only in later times legends were transferred to Corinth. The situation of ACROCORINTHUS is such, that from the remotest period the inhabitants of the country must have used it as a stronghold, as the Isthmus itself is a strong natural fortification for the defence of Peloponnesus, and was afterwards the boundary between the Ionians and the peninsula. According to tradition, Acrocorinthus was in the possession of the Achaeans, and was taken by the Dorians only after a protracted blockade.
