Northamptonshire has proved to be a treasure-house of medieval stained glass, including major monuments such as Lowick and Stanford on Avon. The quantity and range of the glazing at Stanford on Avon, in particular, provides unsurpassed material for the study of English parish church glazing. This first detailed study of the county's medieval stained glass contains over 100 entries, ranging in date from Anglo-Saxon times to the mid-sixteenth century. The range of images, the evidence of patronage revealed by figures and heraldry, and the fresh light shed on workshop practices and organization transcend disciplinary boundaries, and have much to offer everyone interested in medieval history, religion, and visual culture.
