Strabo 5.2.4
As for the Pelasgi, almost all agree, in the first place, that some ancient tribe of that name spread throughout the whole of Greece, and particularly among the Aeolians of Thessaly. Again, Ephorus says that he is of the opinion that, since they were originally Arcadians, they chose a military life, and that, in converting many peoples to the same mode of life, they imparted their name to all, and thus acquired great glory, not only among the Greeks, but also among all other people whithersoever they had chanced to come. For example, they prove to have been colonisers of Crete, as Homer says; at any rate, Odysseus says to Penelope: "But one tongue with others is mixed; there dwell Achaeans, there Cretans of the old stock, proud of heart, there Cydonians and Dorians too, of waving plumes, and goodly Pelasgians." And Thessaly is called "the Pelasgian Argos" (I mean that part of it which lies between the outlets of the Peneius River and Thermopylae as far as the mountainous country of Pindus), on account of the fact that the Pelasgi extended their rule over these regions. Further, the Dodonaean Zeus is by the poet himself named "Pelasgian": "O Lord Zeus, Dodonaean, Pelasgian." And many have called also the tribes of Epirus "Pelasgian," because in their opinion the Pelasgi extended their rule even as far as that. And, further, because many of the heroes were called "Pelasgi" by name, the people of later times have, from those heroes, applied the name to many of the tribes; for example, they have called the island of Lesbos "Pelasgia," and Homer has called "Pelasgi" the people that were neighbours to those Cilicians who lived in the Troad: "And Hippothous led the tribes of spear-fighting Pelasgi, those Pelasgi who inhabited deep-soiled Larissa." But Ephorus' authority for the statement that this race originated in Arcadia was Hesiod; for Hesiod says: "And sons were born of god-like Lycaon, who, on a time, was begotten by Pelasgus." Again, Aeschylus, in his Suppliants, or else his Danaan Women, says that the race of the Pelasgi originated in that Argos which is round about Mycenae. And the Peloponnesus too, according to Ephorus, was called "Pelasgia." And Euripides too, in his Archelaus, says: "Danaus, the father of fifty daughters, on coming into Argos, took up his abode in the city of Inachus, and throughout Greece he laid down a law that all people hitherto named Pelasgians were to be called Danaans." And again, Anticleides says that they were the first to settle the regions round about Lemnos and Imbros, and indeed that some of these sailed away to Italy with Tyrrhenus the son of Atys. And the compilers of the histories of The Land of Atthis give accounts of the Pelasgi, believing that the Pelasgi were in fact at Athens too, although the Pelasgi were by the Attic people called "Pelargi," the compilers add, because they were wanderers and, like birds, resorted to those places whither chance led them.
