Otherwise the later accounts. Wherever within the circle of the Ægean Sea the name of Larissa occurs, there Pelasgians are said to have lived--in the Peloponnesian Argos, in Æolis of Asia Minor, on the island of Lesbos, on the Cayster near Ephesus. It is possibly for this reason that the _Odyssey_ places Pelasgians in Crete, since there, also, there was a Larissæan field near Hierapytna, and Gortyn is said to have been called Larissa in ancient times. From Argos the Pelasgians also became woven into the myths of the neighbouring Arcadia, the ancestral hero of which, Lycaon, is called by Hesiod a son of Pelasgus. Pelasgians were said to have lived once in Attica also. The wall which defended the approach to the citadel of Athens bore the name Pelargicon, and as no one knew what that meant, it was said that it had been corrupted out of Pelasgicon and that the citadel had been built by Pelasgians. These Pelasgians were then said to have been driven out by the Athenians and to have migrated to Lemnos. Why they went precisely to this place we do not know, nor why these Lemnian Pelasgians were called Tyrrhenians. Homer places the Sinties, that is a Thracian tribe, in Lemnos. Remnants of the original inhabitants of the island, who were driven out by the Athenians in about the year 500 B.C., were, a hundred years later, still living on the peninsula of Athos and on the Propontis near Placia and Scylace; they had preserved their old language, which was different from the Greek. In consequence of this and similar traditions, the theory was brought forward in the sixth century that the Hellenes had been preceded in Greece by a Pelasgic race. Since, however, some of the Grecian tribes, as the Arcadians and Athenians, considered themselves to be autochthonous, there was nothing for it but to call the Pelasgians the ancestors of the later Hellenes, and so the whole change was reduced to one of name only. This to be sure was in contradiction of the statements of Homer, who names the Pelasgians among the allies of Troy, and hence evidently considered them to be racially antagonistic to the Greeks. The genealogists and historians of antiquity never got around this contradiction, which was indeed inexplicable with the means at their command.
