In Greece, the establishment of colonies towards the end of the 1st century BC under Caesar, continued by Augustus, coincided with an increase in building activity in the urban centers, which is, among other building activities, expressed by the monumentalization of economic areas and their equipment with Roman building types designated for economic activity such as basilicas, horrea, macella etc. These buildings will be analyzed as figures of reflection within the context of the praxeological model of a 'different' aesthetics. Various factors such as the location of individual commercial buildings (integrated into the square or in a solitary position) or the design of their architectural elements (material, color, use of spolia, etc.) will be taken into account to approximate the autological and heterological dimensions of these economic areas. Using selected case studies, the research project examines the origins and development of Roman Fora and their design in Greece.
