Petrit Latifi

It had been clearly indicated by J.E. Thunmann, back in 1774, that the Albanians alone could possibly be considered as the descendants of the Illyrians. Their origin had been suggested even before (in a letter) by the philosopher Leibniz.

Aside from pointing out historical data, Thunmann also remarked that certain Illyrian names are still used by Albanians: Dasios = Dash; Dida = Dede; Bardhylis = Bardhe, etc. A. Boue, who from 1836 to 1838 journeyed across the Balkans accompanied by various experts, subscribed to Thunmann’s theory. J.G. von Hahn exposed the same view in his learned work Albanesische Studien (Jena, 1853) basing his research on ethnography, history and linguistics.
