Exeter Cathedral Keystones and Carvings functions as "an illustrated introduction to, and explanatory catalogue of all the figurative sculpture that is part of the original interior fabric of the medieval building." The material on the site, which is primarily geared toward art historians and medievalists, was compiled by Avril Kay Henry, former professor of English Medieval Culture at University of Exeter, and the late Anna Carson Hulbert, a well known conservator. The site does not provide a tour through the cathedral so much as it offers photos and explanations of the individual sculptural pieces: "medieval bosses, corbels, labelstops, figurative capitals (and a few other interior carvings) which are an integral part of the medieval interior construction of Exeter Cathedral, Devon, England." Users can browse or search the contents, and a nice introduction and bibliography are both useful supplements. From the homepage, users can access a page that explains navigation and layout of the site, entitled The Resource: Coverage and Use. This one is well worth a stop for medievalists.
