The spread of Mohammedan architecture westward next claims our notice; but want of space will only permit us to mention a small though interesting group of Saracenic buildings which still remains in Sicily; the numerous specimens of the style which exist on the north coast of Africa; and the works erected by the Saracens during their long rule in Spain. The most celebrated Spanish example is the fortress and palace of the Alhambra, begun in 1248, and finished in 1314. This building (Fig. 188) has been measured, drawn, and fully illustrated in an elaborate monograph by our countryman Owen Jones, and has become popularly known by the beautiful reproduction of portions of it which he executed at the Crystal Palace, and of which he wrote an admirable description in his 'Guide-book to the Alhambra Court.' The Mohammedan architecture of Spain is here to be seen at its best; most of its features are those of Arab art, but with a distinguishing character (Fig. 193). [Illustration: FIG. 193.--DOORWAY IN THE ALHAMBRA.] Two other well-known examples are, the Giralda[38] at Seville, and the Mosque at Cordova. The Giralda is a square tower, in fact a minaret on a magnificent scale, divided into panels and richly decorated, and shows a masculine though beautiful treatment wholly different from that of the minarets in Cairo. The well-known Mosque at Cordova is of the simplest sort of plan, but of very great extent, and contains no less than nineteen parallel avenues separated from one another by arcades at two heights springing from 850 columns. The Kibla in this mosque is a picturesque domed structure higher than the rest of the building. The columns employed throughout are antique ones from other buildings, but the whole effect of the structure, which abounds with curiously cusped arches and coloured decoration, is described as most picturesque and fantastic. _Persia and India._ Turning eastwards, we find in Turkey, as has been said, a close adherence to the forms of Byzantine architecture. In Persia, where the people are now fire-worshippers, the Mohammedan buildings are mostly ruined, and probably many have disappeared, but enough remains to show that mosques and palaces of great grandeur were built. Lofty doorways are a somewhat distinctive feature of Persian buildings of this style; and the use of coloured tiles of singular beauty for linings to the walls, in the heads of these great portals, and in other situations to which such decoration is appropriate, is very common: these decorations afford opportunity for the Persian instinct for colour, probably the truest in the whole world, to make itself seen.
