The papers in this collection explore the medieval art, architecture, and archaeology of the city of Mainz and of the middle Rhine valley. They were delivered in 2003, at the first annual conference the Association held in Germany. The contributors embrace a wide range of subjects. Some consider the architecture and archaeology of the early medieval and Romanesque period, including the Carolingian monastery of Lorsch and the cathedrals of Mainz, Speyer, and Worms. Other authors look at high and late Gothic architecture in the region, such as the collegiate church at Oppenheim and the Wernerkapelle at Bacherach. There are, moreover, papers on castle architecture, sculpture, panel painting, liturgical furnishings, and medieval inscriptions. At the centre of discussion stand questions of cult, patronage, iconography, and style. New light is shed particularly on the relationship between the art and architecture in the Rhine valley and France. This collection brings together British, German, and French scholars to discuss the art and architecture of this major centre of artistic creation in medieval Europe and will hopefully be of lasting value to scholarship.
