The customs of Cluny represented a shift from the earlier ideal of a Benedictine monastery as an agriculturally self-sufficient unit. This was similar to the contemporary villa of the more Romanized parts of Europe and the manor of the more feudal parts, in which each member did physical labor as well as offering prayer. In 817 St Benedict of Aniane, the "second Benedict", developed monastic constitutions at the urging of Louis the Pious to govern all the Carolingian monasteries. He acknowledged that the Black Monks no longer supported themselves by physical labor. Cluny's agreement to offer perpetual prayer ("laus perennis", literally "perpetual praise") meant that it had increased a specialization in roles.
