Each one of these mosques has its sainted dead, whose name it bears, and who sleeps by its side, in an adjoining mortuary kiosk; some priest rendered admirable by his virtues, or perhaps a khedive of earlier times, or a soldier, or a martyr. And the mausoleum, which communicates with the sanctuary by means of a long passage, sometimes open, sometimes covered with gratings, is surmounted always by a special kind of cupola, a very high and curious cupola, which raises itself into the sky like some gigantic dervish hat. Above the Arab town, and even in the sand of the neighbouring desert, these funeral domes may be seen on every side adjoining the old mosques to which they belong. And in the evening, when the light is failing, they suggest the odd idea that it is the dead man himself, immensely magnified, who stands there beneath a hat that is become immense. One can pray, if one wishes, in this resting-place of the dead saint as well as in the mosque. Here indeed it is always more secluded and more in shadow. It is more simple, too, at least up to the height of a man: on a platform of white marble, more or less worn and yellowed by the touch of pious hands, nothing more than an austere catafalque of similar marble, ornamented merely with a Cufic inscription. But if you raise your eyes to look at the interior of the dome--the inside, as it were, of the strange dervish hat--you will see shining between the clusters of painted and gilded stalactites a number of windows of exquisite colouring, little windows that seem to be constellations of emeralds and rubies and sapphires. And the birds, you may be sure, have their nests also in the house of the holy one. They are wont indeed to soil the carpets and the mats on which the worshippers kneel, and their nests are so many blots up there amid the gildings of the carved cedarwood; but then their song, the symphony that issues from that aviary, is so sweet to the living who pray and to the dead who dream. . . . ***** But yet, when all is said, these mosques seem somehow to be wanting. They do not wholly satisfy you. The access to them perhaps is too easy, and one feels too near to the modern quarters of the town, where the hotels are full of visitors--so that at any moment, it seems, the spell may be broken by the entry of a batch of Cook's tourists, armed with the inevitable _Baedeker_. Alas! they are the mosques of Cairo, of poor Cairo, that is invaded and profaned. The memory turns to those of Morocco, so jealously guarded, to those of Persia, even to those of Old Stamboul, where the shroud of Islam envelops you in silence and gently bows your shoulders as soon as you cross their thresholds.
