Aborigines

The Aborigines were a mythical people of central Italy, connected in legendary history with Aeneas, Latinus, and Evander. They were supposed to have descended from their mountain home near Reate (an ancient Sabine town) upon Latium, whence they expelled the Siceli and subsequently settled down as Latini under a King Latinus. The most generally accepted etymology of the name (ab origine), according to which they were the original inhabitants (the Greek autochthones) of the country, is inconsistent with the fact that the oldest authorities (e.g. Cato in his Origines) regarded them as Hellenic immigrants, not as a native Italian people. Other explanations suggested are arborigines, "tree-born," and aberrigines, "nomads." Historical and ethnographical discussions have led to no result; the most that can be said is that, if not a general term, "aborigines" may be the name of an Italian stock, about whom the ancients knew no more than ourselves.
