This is the old "Fallmerayer Thesis" that was proposed by an Austrian scholar of that name. His argument ran that the "ancient" Greeks had pretty well all perished in the course of the extensive plagues and invasions of late antiquity and the early middle ages and that the modern inhabitants of Greece were mostly descendants of Slavic immigrants with a later admixture of Albanians. This got a lot of notice because it was published in the 1830s at the very time the Greeks were struggling for their freedom from Turkish rule. The Greeks were getting a lot of sympathy at the time because they were the heritors of the glorious civilization of ancient Greece, especially since educated people in Europe and elsewhere were far better educated in the classics than today. I guess the corollary was that it was somehow more acceptable for the Turks to oppress Slavs and Albanians than the heritors of Aeschylus, Phidias and Plato, odd though that may seem to us today. I love how JLib will accasionally alight onto a thread and dispense actual knowledge. Thank you. Why occasionally did the same, but I haven't seen him round these here parts for many a moon. Is there any equivalent theory explaining the brain drain of the Italians? How did the same race give us both Leonardo Da Vinci and "The Situation"?
