Stained glass windows allow the shaping and blending of light within architectural spaces. Color, texture, transparency, design, and composition are all elements that can be varied and explored to create new light effects and bring space to its full potential. The twentieth century, with its architectural revolution in methods and materials, opened up new possibilities for stained glass. Studies of this phenomenon have been rare until now, and this book is a pioneer in the survey of this fascinating field. 246 color illustrations.
