Note 9 — Chapter VI · CHURCHES AND CATHEDRALS OF THE TWELFTH AND THIRTEENTH CENTURIES
Florence Simmonds translation
It is possible, if not easy, to trace the architectural development of the Middle Ages in a good many cathedrals and churches of the twelfth and thirteenth centuries. We have, however, confined ourselves, for the purposes of our present synthesis, to the churches and cathedrals of the royal domain, and more especially of the Ile-de-France, not only because they served as models for the architects of their day, but because they illustrate in a remarkable degree the various transitions we desire to study.
