It has afforded an attractive study to philologists, amongst whom may be mentioned Malte-Brun, Leake, Xylander, Hahn, Miklosich and G.
An alphabet of fifty-two letters, some presenting ancient Phoenician and Cretan forms, was found by Hahn in partial use at Elbassan and Tirana; its antiquity, however, has not been established.
"Cyclopean" structures were discovered by Hahn at Kretzunista, Arinista, and other sites in the district of Argyrokastro; the walls, partly "Cyclopean," of an ancient city (perhaps Bullis) are visible at Gradisti on the Viossa.
