Luwian language
Lycian culture was at one time viewed as a branch of Greek culture by scholars, especially from the Classical period onwards, when Lycian architecture and sculpture were very much in the Classical Greek style. But the Lycians had a distinct culture of their own, and their religious and funerary rites can be distinguished from the Greek. The Lycian language, although it is Indo-European, is related to Hittite and most probably directly descended from the related Luwian language. Several groups speaking Hittite-related languages continued to exist in Asia Minor for many centuries after the Hittite Empire had passed into history.
