Borza, Eugene N. (1992). In the Shadow of Olympus: the Emergence of Macedon (Revised Edition). Princeton, New Jersey: Princeton University Press. "Speakers of these various Greek dialects settled different parts of Greece at different times during the Middle Bronze Age, with one group, the 'northwest' Greeks, developing their own dialect and peopling central Epirus. This was the origin of the Molossian or Epirotic tribes." "[...]a proper dialect of Greek, like the dialects spoken by Dorians and Molossians." "The western mountains were peopled by the Molossians (the western Greeks of Epirus)."
Hammond, NGL (1994). Philip of Macedon. London, UK: Duckworth. "Epirus was a land of milk and animal products...The social unit was a small tribe, consisting of several nomadic or semi-nomadic groups, and these tribes, of which more than seventy names are known, coalesced into large tribal coalitions, three in number: Thesprotians, Molossians and Chaonians...We know from the discovery of inscriptions that these tribes were speaking the Greek language (in a West-Greek dialect)"
