The Meuse river valley lay in the heart of the earlier Carolingian Empire and therefore the style draws largely from the heritage of the Carolingian art tradition. Thus, Mosan art contains strong classical elements, which separates it from the international Romanesque style seen elsewhere during the period, for example in France,[1] Germany[2] Spain and Italy. However, it shares with mainstream Romanesque art elements such as the treatment of space. Although the iconography of 11th- and 12th-century Meuse valley art largely draws on Biblical inspiration, some of the elaborately carved capitals in the two main churches in Maastricht depict scenes from many aspects of daily life, as well as images from an intriguing world of fantasy.
Mosan architecture can be seen as a distinctive branch in Romanesque architecture, a regional style that produced imposing churches in Aachen, Liège and Maastricht, as well as monasteries in rural areas. The fully developed Mosan style of the 12th century is a comprise between the older Meuse valley traditions and foreign influences, mainly coming from the Rhineland and Italy. An outstanding factor in Mosan architecture is the closed west front (westwerk). Unfortunately, some of the largest churches, notably Liège cathedral, and the Stavelot and Sint-Truiden abbeys, were destroyed.
Mosan stone carving reached a peak in the 12th century in Maastricht, Liège and Nivelles. Maastricht 'metsen' (stone carvers) worked on capitals and reliefs as far afield as Utrecht, Bonn and Eisenach.
Very little has come to us from what must have been an impressive body of Mosan murals. Wolfram von Eschenbach, in his Parzival expressed his high regard for Maastricht (and Cologne) painters (Parzival, 158, 13-16). Book illumination, like the rest of the arts, was at its zenith in the second half of the 12th century. The principal centres were the abbey of Saint Laurent in Liège and the abbeys of Stavelot and Lobbes. Another highly developed art was vitreous enameling.
