ABSTRACT
The Church of Saint-Séverin, in the centre of Paris, features parts that were built at different times, although the ambulatory was built relatively homogeneously. In it we find a network of triangular vaults each with three converging ribs. Some of the elements of these vaults, which should appear symmetrically on each side of the temple axis, have nevertheless been arranged somewhat differently. These irregularities correspond perfectly with the arrangement of mouldings in the fasciculate shaft and with the forms in the bases. This paper presents constructive aspects of the Late Gothic forms of Saint-Séverin, especially the particularities of the coordination of the elements of the vaults and their supports, as an expression of the mastery of a technique.
