The Geometry of the Choir Plan in Suger’s Saint-Denis

  • I’m pleased to have this opportunity to address a session with such a strong geometrical component. I’m also happy to say that my geometrical work has given me a new perspective on Suger’s Saint-Denis, one of the most influential monuments in the history of medieval architecture. I believe that I now understand in reasonable detail the geometrical thinking that governed the east end of the church, whose ambulatory vaults are seen here. This pattern of vault ribs, of course, demands to be understood in the context of the structure’s overall plan.
