"For the human eye... marvels at the inestimable beauty of the glass and the infinitely rich and various workmanship." (Theophilus, early twelfth century) But what do we really know of the men and women who made stained glass windows, and the methods they used? Stained glassed was an invaluable medium for communicating religion to a largely illiterate populace and the glass-painter was its creator. This book describes the fascinating origins of the cragt and the techniques emplyed - including the design, colouring, and use of pattern books. The authors explain the circumstances of commission, who the patrons were, and how the glass-painter both designed and executed the window. They then discuss evidence of the education, position in society, and working practices of glass-painters. Finally, the recount the decline of this resplendent craft and the sad destruction of the windows as the Reformation and changes in fashion both took their toll. Beautifully illustrated with examples from cathedrals, churches, and castles throughout Europe, this book will enrich the understanding of all lovers of medieval art and architecture.
