All rights reserved.Through the combined study of the Hittite cuneiform texts and the archaeological data, we try to draw a map of the Hūlaya river land, a Luwian-speaking area of the Hittite kingdom. The philological inquiry focuses on two diplomatic treaties that were established by the Great King of Hatti and the king of Tarhuntašša, whose territory was closely connected to the Hūlaya river land. The archaeological inquiry summarizes several survey campaigns performed in the region, including the surveys that we performed in the vicinity of Fasıllar (province of Beyşehir) between 2012 and 2015. Our methodology is based on reconstructing the ancient roads of the region, in order to restitute the urban network of the Hittite period.
