This book explains in detail the practice of masoncraft in the Middle Ages using evidence from a number of sources. Monastic chronicles building contracts & other contemporary documents have already revealed a good deal of information on the subject but less attention has until now been paid to archaeological evidence preserved in numerous surviving Medieval buildings. Dr Hislop investigates how a study of certain features in these buildings such as the stonework & building joints can contribute to our knowledge of working practices of masons in medieval Engl&. By focusing on how to interpret clues in the building structure this account provides a practical guide to pursuing the study of masonry & helps the reader to understand & identify the medieval masons approach to design & constructional techniques.
