Presenting research by an international community of scholars, this book explores through a series of cross sections the traffic of ideas between practice and history that has shaped modern architecture and the academic discipline of architectural history across the long twentieth century. The editors use the historiography of the baroque as a lens through which to follow the path of modern ideas that draw authority from history. In doing so, the volume defines a role for the baroque in the history of architectural historiography and in the history of modern architectural culture.
