Geometric Analysis of Two Brick Ribbed Vaults from the 14th Century in Aragón

Abstract

The control of the geometry during the Middle Ages allowed the right trace and drawing of ribbed vault, element that defines the gothic construction. The divulgation of this style caused a large amount of regional variances that were translated into diverse formal and material varieties. This study will carry out an architectonic surveying and following analysis of two ribbed vaults built in Aragon, both made of reloja and aljez (brick and cast), during the 14th century, with the objective to deepen knowledge and understanding. The accuracy that requires a formal exhaustive analysis, out of simplifications, has required an appropriate surveying methodology. After the construction of the 3D models it has been possible to extract the accurate geometry of the arches that defines the vaults, to be able to proceed with the geometrical analysis. As a result of this research it will be possible to establish accurately their original curvature and position, which will allow to compare the drawings of the different arches that conform the vaults and, therefore, to establish the relevance of the geometrical trace previous to the construction.
