• the late, fully developed Romanesque of the eleventh and twelfth centuries, which comprises the advanced and differentiated Lombard, Rhenish, Saxon, Norman, and Burgundian styles. The latter division, while retaining the semicircular arch and other characteristic features of Roman architecture, is in every sense an original style of great richness and dignity, always inferior, however, to the succeeding Pointed style in the less perfect stability of its round arch and vault, the greater heaviness and less organic quality of its structure (the Romanesque architect, like the old Roman, still trusting for stability rather to the massiveness of his walls than, like his succcessor in the thirteenth century, to the scientific combination of a skeleton framework of masonry), the inferior flexibility of its design, and the archaic character of its figure-sculpture, of which much, however, is admirable in the best examples, particularly in France. See medieval architecture (under medieval), and compare cuts under Norman, Rhenish, and modillion.
• noun The early medieval style of architecture and ornament founded in the West upon those of the later Roman empire, and the varieties into which it is subdivided, known as Lombard, Norman, Rhenish, etc. See I.
• noun The common dialect of Languedoc and some other districts in the south of France.
