But the true splendour of Palermo, that which makes this city one of the most glorious of the South, is to be sought in its churches--in the mosaics of the Cappella Palatina founded by King Roger, in the vast aisles and cloisters of Monreale built by King William the Good at the instance of his Chancellor Matteo,[6] in the Cathedral of Palermo begun by Offamilio, and in the Martorana dedicated by George the Admiral. These triumphs of ecclesiastical architecture, none the less splendid because they cannot be reduced to rule or assigned to any single style, were the work of Saracen builders assisted by Byzantine, Italian, and Norman craftsmen. The genius of Latin Christianity determined the basilica shape of the Cathedral of Monreale. Its bronze doors were wrought by smiths of Trani and Pisa. Its walls were incrusted with the mosaics of Constantinople. The woodwork of its roof, and the emblazoned patterns in porphyry and serpentine and glass and smalto, which cover its whole surface, were designed by Oriental decorators. Norman sculptors added their dog-tooth and chevron to the mouldings of its porches; Greeks, Frenchmen, and Arabs may have tried their skill in turn upon the multitudinous ornaments of its cloister capitals. “The like of which church,” says Lucius III in 1182, “hath not been constructed by any king even from ancient times, and such an one as must compel all men to admiration.” These words remain literally and emphatically true. Other cathedrals may surpass that of Monreale in sublimity, simplicity, bulk, strength, or unity of plan. None can surpass it in the strange romance with which the memory of its many artificers invests it. None again can exceed it in richness and glory, in the gorgeousness of a thousand decorative elements subservient to one controlling thought. “It is evident,” says Fergusson in his history of architecture, “that all the architectural features in the building were subordinate in the eyes of the builders to the mosaic decorations, which cover every part of the interior, and are in fact the glory and the pride of the edifice, and alone entitle it to rank among the finest of mediæval churches.” The whole of the Christian history is depicted in this series of Mosaics; but on first entering, one form alone compels attention. The semi-dome of the eastern apse above the high altar is entirely filled with a gigantic half-length figure of Christ. He raises His right hand to bless, and with His left holds an open book on which is written in Greek and Latin, “I am the Light of the World.” His face is solemn and severe, rather than mild or piteous; and round His nimbus runs the legend Ἰησους χριστὸς ὁ παντοκράτωρ. Below Him on a smaller scale are ranged the archangels and the mother of the Lord, who holds the child upon her knees. Thus Christ appears twice upon this wall, once as the Omnipotent Wisdom, the Word by whom all things were made, and once as God deigning to assume a shape of flesh and dwell with men.
