 Frank Starke of the University of Tübingen concludes that "the certainty is growing that Wilusa/Troy belonged to the greater Luwian-speaking community".Joachim Latacz also regards Luwian as the official language of Homeric Troy, but he finds it highly probable that another language was in daily use.Ilya Yakubovich provides a critical evaluation of the arguments by Watkins and Starke in his University of Chicago dissertation and concludes that the ethnicity of the Trojans remains completely unknown.
