Diodorus of Sicily, writing about Bardylis, the Illyrian King of Dardania

Diodorus of Sicily, when writing about Bardylis, the Illyrian King of Dardania, mentions his name in the form "βάρδυλλις," where "δ" in Greek is pronounced as "dh," and with a double "λ" making it "ll," thus Bardhyll, with the Greek suffix -is added.

According to some scholars and linguists, including Alexandru Rosseti, Pavle Ivić, Bardhyl Demiraj, Stefan Schumacher, Joachim Matzinger, and others, this name is connected to the Albanian words bardhë (white) and yll (star), meaning "white star." “βάρδυλλις δ ' ὁ τῶν ἰλλυριῶν βασιλεὺς” - Bardhyl, the King of Illyria (since Dardania was an Illyrian city-state), is also mentioned in other documents as the Illyrian King of Dardania.
