Monasticism

The system of monasticism in which the religious become members of an order, with common ties and a common rule, living in a mutually dependent community, rather than as a group of hermits living in proximity but essentially separate, was established by the monk Benedict in the 6th century. The Benedictine monasteries spread from Italy throughout Europe, being always by far the most numerous in England. They were followed by the Cluniac order, the Cistercians, Carthusians and Augustinian Canons. During the Crusades, the military orders of the Knights Hospitaller and the Knights Templar were founded.

The monasteries, which sometimes also functioned as cathedrals, and the cathedrals that had bodies of secular clergy often living in community, were a major source of power in Europe. Bishops and the abbots of important monasteries lived and functioned like princes. The monasteries were the major seats of learning of all sorts. Benedict had ordered that all the arts were to be taught and practiced in the monasteries. Within the monasteries books were transcribed by hand, and few people outside the monasteries could read or write.

In France, Burgundy was the centre of monasticism. The enormous and powerful monastery at Cluny was to have lasting effect on the layout of other monasteries and the design of their churches. Very little of the abbey church at Cluny remains; the "Cluny II" rebuilding of 963 onwards has completely vanished, but we have a good idea of the design of "Cluny III" from 1088 to 1130, which until the Renaissance remained the largest building in Europe. However, the church of St. Sernin at Toulouse, 1080–1120, has remained intact and demonstrates the regularity of Romanesque design with its modular form, its massive appearance and the repetition of the simple arched window motif.
