Cairene architecture
The architecture of Cairo in Egypt, especially the architecture of Saracenic or, more properly speaking, Moslem style. The mosques of Cairo contain the richest ornamentation of the unaltered style invented for the Arabian conquerors by the Byzantine Greeks who worked under their direction, which style was much corrupted in North Africa and in Spain. This Cirene architecture has, then, the peculiar value of having preserved for us the best examples of this curious school of design, and the richest and most tasteful pieces of its ornamentation.
