Strabo Geography 5.2.4

[4] Almost every one is agreed that the Pelasgi were an ancient race spread throughout the whole of Greece, but especially in the country of the Aeolians near to Thessaly. Ephorus, however, says that he considers they were originally Arcadians, who had taken up a warlike mode of life; and having persuaded many others to the same course, imparted their own name to the whole, and became famous both among the Greeks, and in every other country where they chanced to come. Homer informs us that there were colonies of them in Crete, for he makes Ulysses say to Penelope—

Diverse their language is; Achaians some,

And some indigenous are; Cydonians there,

Crest-shaking Dorians, and Pelasgians dwell. ¹

Odyssey xix. 175. And that portion of Thessaly between the outlets of the Peneius ² and the Thermopylae, as far as the mountains of Pindus, is named Pelasgic Argos, the district having formerly belonged to the Pelasgi. The poet himself also gives to Dodonaeman Jupiter, the epithet of Pelasgian:—

Pelasgian, Dodonaean Jove supreme. ³

Iliad xvi. 223. Many have likewise asserted that the nations of the Epirus are Pelasgic, because the dominions of the Pelasgi extended so far. And, as many of the heroes have been named Pelasgi, later writers have applied the same name to the nations over which they were the chiefs. Thus Lesbos ⁴ has been called Pelasgic, and Homer has called the people bordering on the Cilices in the Troad Pelasgic:—

Hippothous from Larissa, for her soil

Far-famed, the spear-expert Pelasgians brought. ⁵

Iliad ii. 840 Ephorus, when he supposes that they were a tribe of Arcadians, follows Hesiod, who says, Likewise Aeschylus in his Suppliants, or Danaids, makes their race to be of Argos near Mycenae. Ephorus likewise says that Peloponnesus was named Pelasgia; and Euripides, in the Archelaus, says, Anticlides says, that they first colonized about Lemnos and Imbros, and that some of their number passed into Italy with Tyrrhenus, the son of Atys. And the writers on the Athenian Antiquities, ⁷ relate of the Pelasgi, that some of them came to Athens, where, on account of their wanderings, and their settling like birds in any place where they chanced to come, they were called by the Athenians Pelargi. ⁸
