No Need Of Styles: Building Up Architectural Historiography, Carmen Popescu

Artl@s Bulletin

If styles lost impetus within the methodology of art historiography, in the (parallel) field of architecture, they were firmly rejected one century ago. One might consider that this more radical positioning (particularly in terms of epistemological tools) constituted the very reason for the undeclared but yet consumed divorce between the two disciplines. Attempting to define its specificity but also the autonomy of the discipline, architectural historiography followed a path less directly preoccupied with aesthetics and closer to functionality and technicity. My paper analyses how architectural historiography built up its idiosyncrasy.
