Abstract

Abstract: Architectural historians have identified Wells cathedral as a key monument in the transition between high and late Gothic, a move in part characterised by the rejection of simple quadripartite or tierceron rib vaults for more complex vaults. Here we will show how digital methods are used to reopen questions of design and construction first posed in 1841 by pioneer architectural historian Robert Willis. Digital laser scanning documents vaults accurately, thereby establishing their geometries to a high degree of certainty and, at Wells, highlighting differences between the choir aisle bays which have previously been treated as a single design. Significantly, we will show how digital techniques can be used to investigate these differences further, using point cloud data as a starting point for analysis rather than an end point. Thus we will demonstrate how modern technologies have the potential to reignite historic debates and transform scholarly enquiries. Highlights: Point cloud models can be used to identify differences requiring more detailed analysis. Tracing of mesh models allows us to establish the geometry of the vault ribs. Digital reconstructions enable us to reverse-engineer the design and construction process of a sample bay. The validity of Robert Willis's hypotheses is confirmed and his research augmented.
