Abstract
In the 1940s, when studies on the conceptualization of Turkish Art increased even more with the feeling of nationalism, it is important to examine Turgut Cansever's PhD thesis named "Turkish Column Headings" in order to better understand the historiographic approaches. Because Cansever is the student of Art History Professor Ernst Diez, one of the important names of this conceptualization, and is the only architect in the world to win the Aga Khan Architecture Awards three times in the later stages of his career. In his thesis, before the documentation of structures and columns part, there is a theoretical and conceptual part, which is perhaps more important than the documentation part. In this part, the characteristics of Seljuk and Ottoman Art (Turkish Art) are mentioned. Along with this part, where an important influence of Diez can be observed, in this study, it is aimed to analyze the method put forward in Cansever's PhD thesis in a holistic manner in the contexts of "Geography and Culture", "Type" and "Technical", one of Leach (2010)'s architectural historiography approaches.
