Focusing on the differences and similarities between the renowned 'Alpais' Limoges ciborium, dated to c. 1200, in the Musée du Louvre, and examples in the British Museum, the National Museums of Scotland, together with two electrotype copies of the 'Alpais' ciborium in the Victoria and Albert Museum, this volume uses a cross-disciplinary approach, based on the differing specialisations of the authors (curators, scientists and conservators) to examine the group of ciboria. New and previously unpublished information, analyses and conclusions are presented that will serve to locate all the ciboria in their respective artistic and cultural context.
