This new introduction to stained glass in Britain traces the story of this extraordinary art form from its beginnings, illustrating magnificent 12th-century windows from Canterbury Cathedral and elsewhere, before explaining the development of the stained glass windows through the medieval period, as new techniques were developed, and the art of storytelling in glass reached ever greater heights. During the 17th and 18th centuries techniques changed, with emphasis moving from stained to painted glass, and a new emphasis on non-religious subjects, but in the 19th century medieval techniques and subjects were revived, and these windows from the gothic revival period constitute the great majority of the British national collection of glass. The 20th century has seen a new flowering of stained glass, and at both old churches and new, modern glass is a striking and highly effective feature.
