This handsome two-part set is the first fully illustrated study of one of the most substantial collections of medieval stained glass in England. In particular, the glass from the east end of Wells Cathedral (rebuilt by a thriving clerical community in 1320-40) includes the five brilliantly coloured windows of the choir clerestory, with its seven-light Jesse east window, and glass from the famous polygonal Lady Chapel. Besides describing and illustrating each panel, the volume has introductions to each part of the cathedral complex. What is known of the original glazing and its history is reconstructed, and many new discoveries are revealed. An introduction places the findings within the wider context of recent international stained glass studies and late medieval art history.
