Flint Flushwork is a wholly external decorative medium, where the skills of medieval craftsman blended with the iconography of the medieval church to create a unique new art form. It is an artistic achievement that is built into the very fabric of many hundreds of medieval churches. As such, many examples of Flushwork survive where more impermanent artworks have succumbed to the ravages of reformation and over-zealous restoration. Despite this, however, ithas not attracted the same depth of research and analysis as other aspects of church architecture. This book provides a wide perspective on the several different modes of Flushwork that have been identified. By elucidating, and putting within their architectural and spiritual context, the various strands of the art, it aims to encourage a greater understanding and wider appreciation of this relatively uncharted branch of church art.
