Durand and the science of architecture

This essay addresses some critical issues concerning the systematization of architectural knowledge. The work of Jean-Nicolas-Louis Durand provides a context within which to discuss the degree to which architecture can be subjected to a process of systematization. Durand's work is analyzed by reconstructing the logical steps in the development of his theoretical system. As a result of this reconstruction, some of the key issues of his theory are unveiled. Thus, for example, it will be shown that an idea of type emerges progressively as his theory matures. The examination of Durand's ideas is based not only on his writings, but also on the drawings that illustrate his books. Indeed, an idea that runs through the whole essay is that graphic representations play a crucial role in the systematization of architectural knowledge.
