time to have no walls or fortifications. It was destroyed by fire around 1180 BC and many clay tablets in linear B clearly bear the stigmata of the fire. The Linear B archives found there, preserved by the heat of the fire that destroyed the palace, mention hasty defence preparations due to an imminent attack without giving any detail about the attacking force. The site of the Mycenaean Pylos then seems to have been abandoned during the Dark Ages (1100–800 BC). The region of Pylos, together with that of the ancient Messene, was later enslaved by Sparta. The ruins of a crude stone fortress on nearby Sphacteria, apparently of Mycenaean origin, were used by the Spartans during the Peloponnesian War. (Thucydides iv. 31) Classical Pylos It was one of the last places which held out against the Spartans in the Second Messenian War, after which the inhabitants emigrated to Cyllene, and from there, with the other Messenians, to Sicily. Its name is mentioned again in the seventh year of the Peloponnesian War. According to the Greek historian Thucydides in his History of the Peloponnesian War, the area was "together with most of the country round, unpopulated". The ancient city was not located at the modern Pylos, but north of the isle of Sphacteria. In 425 BC the Athenian politician Cleon sent an expedition to Pylos where the Athenians fortified the rocky promontory now known as Koryphasion (Κορυφάσιον) or Old Pylos at the northern edge of the bay, near the Gialova Lagoon, and after a conflict with Spartan ships in the Battle of Pylos, seized and occupied the bay. Demosthenes, the Athenian commander, completed the fort in 424 BC. The erection of this fort led to one of the most memorable events in the Peloponnesian War. Thucydides has given a minute account of the topography of the district, which, though clear and consistent with itself, does not coincide, in all points, with the existing locality, Thucydides describes the harbour, of which the promontory Coryphasium (Koryphasion) formed the northern termination, as fronted and protected by the island Sphacteria, which stretched along the coast, leaving only two narrow entrances to the harbour,--the one at the northern end, opposite to Coryphasium, being only wide enough to admit two triremes abreast, and the other at the southern end wide enough for eight or nine triremes. The island was about 15 stadia in width, covered with
