The churches of medieval Europe contained richly carved and painted screens, placed between the altar and the congregation; they survive in particularly high numbers in England, despite being partly dismantled during the Reformation. While these screens divided lay from priestly jurisdiction, it has also been argued that they served to unify architectural space. This volume brings together the latest scholarship on the subject , exploring in detail numerous aspects of the construction and painting of screens, it aims in particular to unite perspectives from science and art history. Examples are drawn from a wide geographical range, from Scandinavia to Italy.
