This new publication brings together a range of leading scholars from Europe, America and the Middle East to discuss the most recent research in the field of Byzantine glass and mosaics in an interdisciplinary context. New Light on Old Glass explores how mosaics are perhaps the most outstanding examples of Byzantine art which survive; revealing changing aesthetics and issues surrounding the technical production of glass in medieval artistic practices. This is the first time that so many diverse papers, ranging from art history, archaeology, chemistry, physics and Byzantine studies have been assembled in one volume, and is the culmination of a five-year research programme on the Composition of Byzantine Glass Mosaic Tesserae, conducted by the University of Sussex in conjunction with the British Museum and sponsored by the Leverhulme Trust.
