12世紀,13世紀イル・ド・フランスにおける支柱組織の展開について : 6分ヴォールトの諸問題その4

Abstract

The transition of the pier system in Ile-de-France from the early 12 th century to the early 13 th century is the process that heavy compound piers are replaced with slender colomns by stages. At Early Gothic the sexpartite vault was employed in order to accommodate to the remarkable alternation of the pier system witch was the result that the heavy compound piers have been replaced with slender columns on every other piers. The intermediate pier of Early Gothic sexpartite vaulting church has shafts standing on the capital, from witch terminals arches and ribs depart. I think that such a composition (column-constitution) was originally created when constructors made a trial to cover the apse of ambulatory type choir with rib vault. In this paper, I treat of the evolution of pier constitutions in the whole central space including both choir and nave. As a result, it is able to be considered that the evolution of pier-constitutions of Ile-de-France, from the early 12 th centuy to the early 13 th century, is the process that the column-constitution which was created in the apse of the ambulatory type choir spreads over the other portions of the central space gradually.
