and Heuneburg. After lengthy wars, the Roman Empire settled its frontiers in Germania with the Limes Germanicus to include much of the south and west of modern Germany. The German provinces produced art in provincial versions of Roman styles, but centres there, as over the Rhine in France, were large-scale producers of fine Ancient Roman pottery, exported all over the Empire. Rheinzabern was one of the largest, which has been well-excavated and has a dedicated museum. Non-Romanized areas of the later Roman period fall under Migration Period art, notable for metalwork, especially jewellery (the largest pieces apparently mainly worn by men). Middle Ages German medieval art really begins with the Frankish Empire of Charlemagne (d. 814), the first state to rule the great majority of the modern territory of Germany, as well as France and much of Italy. Carolingian art was restricted to a relatively small number of objects produced for a circle around the court and a number of Imperial abbeys they sponsored, but had a huge influence on later Medieval art across Europe. The most common type of object to survive is the illuminated manuscript; wall paintings were evidently common but, like the buildings that housed them, have nearly all vanished. The earlier centres of illumination were located in modern France, but later Metz in Lorraine and the Abbey of Saint Gall in modern Switzerland came to rival them. The Drogo Sacramentary and Folchard Psalter are among the manuscripts they produced. No Carolingian monumental sculpture survives, although perhaps the most important patronage of Charlemagne was his commissioning of a life-size gold figure of Christ on a crucifix for his Palatine Chapel in Aachen; this is only known from literary references and was probably gold foil around a wooden base, probably modelled with a gesso layer, like the later and rather crumpled Golden Madonna of Essen. Early Christian art had not featured monumental sculptures of religious figures as opposed to rulers, as these were strongly associated by the Church Fathers with the cult idols of Ancient Roman religion. Byzantine art and modern Eastern Orthodox religious art have maintained the prohibition to the present day, but Western art was apparently decisively influenced by the example of Charlemagne to abandon it. Charlemagne's circle wished to revive the glories of classical style, which they mostly knew in its Late Antique form, and also to compete with Byzantine art, in which they appear
