Cathedral of Monreale, Apse Cathedral Tilework Detail
The Cathedral of Monreale is one of the greatest extant examples of Norman architecture in the world. It was begun in 1174 by William II, and in 1182 the church, dedicated to the Assumption of the Virgin Mary, was, by a bull of Pope Lucius III, elevated to the rank of a metropolitan cathedral.
The church’s plan is a mixture of Eastern Rite and Roman Catholic arrangement. The nave is like an Italian basilica, while the large triple-apsed choir is like one of the early three-apsed churches, of which so many examples still exist in Syria and other Oriental countries. It is, in fact, like two quite different churches put together endwise.
It is, however, the large extent (6,500 m2) of the impressive glass mosaics covering the interior which make this church so splendid. With the exception of a high dado, made of marble slabs with bands of mosaic between them, the whole interior surface of the walls, including soffits and jambs of all the arches, is covered with minute mosaic-pictures in bright colors on a gold ground. The mosaic pictures are arranged in tiers, divided by horizontal and vertical bands. In parts of the choir there are five of these tiers of subjects or single figures one above another.
