Mapping Gothic France

• From the site: "Whereas pictures can be satisfactorily represented in two dimensions on a computer screen, space -- especially Gothic space -- demands a different approach, one which embraces not only the architectonic volume but also time and narrative. Mapping Gothic France builds upon a theoretical framework derived from the work of Henri Lefèbvre (The Production of Space) that seeks to establish linkages between the architectural space of individual buildings, geo-political space, and the social space resulting from the interaction (collaboration and conflict) between multiple agents -- builders and users. 

  "Mapping Gothic France will, we hope, become a vital educational and research tool for both students and scholars. We invite you to explore the site, and welcome both your comments and scholarly contributions to the narratives." Brought to you by Vassar's Andrew Tallon and Columbia's Stephen Murray.
