Pelasgi, a people who in prehistoric times occupied Greece, the Archipelago, the shores of Asia Minor, and great part of Italy, and who were subdued, and more or less reduced to servitude, by the Hellenes, and supplanted by them. They appear to have been, so far as we find them, an agricultural people, settled and not roving about, and to have had strongholds enclosed in cyclopean walls, that is, walls consisting of huge boulders unconnected with cement.
