The first person to point to the Hittite texts as a possible primary source was the Swiss scholar Emil Forrer in the 1920s and 1930s. In discussing an ethnic group called the "Ahhiyawa" in these texts, Forrer drew attention to the place names "Wilusa" and "Taruisa", which he argued were the Hittite way of writing "Wilios" (Ϝίλιος, old form of "Ιlios") and "Troia" (Troy). He also noted the mention of a Wilusan king Alaksandu, who had concluded a treaty with the Hittite king Muwatalli; the name of this king closely resembled Alexandros/Alexander, the alternative name of Paris, the son of king Priam. Other identifications Forrer offered included Priam with Piyama-Radu, and Eteocles, king of Orchomenos, with one "Tawagalawa". However, despite his arguments, many scholars dismissed Forrer's identification of Wilusa-(W)ilios/Troia-Taruisa as either improbable or at least unprovable, since until recently the known Hittite texts provided no clear indication where the kingdom of Wilusa was located beyond somewhere in Western Anatolia.
