Egypt is so old that even the Roman times appear new, and one is tempted to regard these glorious buildings of the Mohammedan era as only of yesterday. Yet many of the mosques which people visit and admire are older than any church or cathedral in England. We all think of Lincoln Cathedral or Westminster Abbey as being very venerable buildings, and so they are; but long before they were built the architecture of the Mohammedans in Egypt had developed into a perfect style, and produced many of the beautiful mosques in which the Cairene prays to-day. As a rule the mosque was also the tomb of its founder, and the dome was designed as a canopy over his burial-place, so that when a mosque is _domed_ we know it to be the mausoleum of some great man, while the beautiful minaret or tower is common to all mosques, whether tomb-mosque or not. One of the most striking features of a mosque is the doorway, which is placed in a deep arched recess, very lofty and highly ornamented. A flight of stone steps lead from the street to the door, which is often of hammered bronze and green with age, and from a beam which spans the recess hang curious little lamps, which are lit on fete days. At the top of the steps is a low railing or barrier which no one may cross _shod_, for beyond this is holy ground, where, as in the old days of Scripture, every one must "put off his shoes from off his feet." The interior of the mosque is often very rich and solemn. It is usually built in the form of a square courtyard, open to the sky, in which is the "hanafieh," or tank, where "the faithful" wash before prayers. The court is surrounded by cloisters supported by innumerable pillars, or else lofty horseshoe arches lead into deep bays or recesses, the eastern one of which, called the "kibleh," is the holiest, and corresponds to our chancel, and in the centre of the wall is the "mirhab," or niche, which is in the direction of Mecca, and the point towards which the Moslem prays. Marble pavements, beautiful inlay of ivory and wood, stained-glass windows, and elaborately decorated ceilings and domes, beautify the interior, and go to form a rich but subdued coloured scheme, solemn and restful, and of which perhaps my picture will give you some idea. Attached to most mosques is a sebīl, also beautiful in design. The lower story has a fountain for the use of wayfarers; above, in a bright room open to the air, is a little school, where the boys and girls of the quarter learn to recite sundry passages from the Koran, and which until recently was practically all the education they received.
