Featureless walls of mean houses close in again at the next turn; but a few steps farther another archway reveals another secret scene. This time it is a corner of the jealously guarded court of ablutions in the great mosque El Kairouiyin, with the twin green-roofed pavilions that are so like those of the Alhambra.

Those who have walked around the outer walls of the mosque of the other Kairouan, and recall the successive doors opening into the forecourt and into the mosque itself, will be able to guess at the plan of the church of Fez. The great Almohad sanctuary of Tunisia is singularly free from parasitic buildings, and may be approached as easily as that of Cordova, but the approaches of El Kairouiyin are so built up that one never knows at which turn of the labyrinth one may catch sight of its court of fountains, or peep down the endless colonnades of which the Arabs say: "The man who should try to count the columns of Kairouiyin would go mad."

Marble floors, heavy whitewashed piers, prostrate figures in the penumbra, rows of yellow slippers outside in the sunlight—out of such glimpses one must reconstruct a vision of the long vistas of arches, the blues and golds of the mirhab,[A] the lustre of bronze chandeliers, and the ivory inlaying of the twelfth-century minbar[B] of ebony and sandalwood.

No Christian footstep has yet profaned Kairouiyin, but fairly definite information as to its plan has been gleaned by students of Moroccan art. The number of its "countless" columns has been counted, and it is known that, to the right of the mirhab, carved cedar doors open into a mortuary chapel called "the mosque of the dead"—and also that in this chapel, on Fridays, old books and precious manuscripts are sold by auction.

This odd association of uses recalls the fact that Kairouiyin is not only a church but a library, the University of Fez as well as its cathedral. The beautiful Medersas with which the Merinids adorned the city are simply the lodging-houses of the students, the classes are all held in the courts and galleries adjoining the mosque.

El Kairouiyin was originally an oratory built in the ninth century by Fatmah, whose father had migrated from Kairouan to Fez. Later it was enlarged, and its cupola was surmounted by the talismans which protect sacred edifices against rats, scorpions and serpents, but in spite of these precautions all animal life was not successfully exorcised from it. In the twelfth century, when the great gate Ech Chemmâin was building, a well was discovered under its foundations. The mouth of the well was obstructed by an immense tortoise, but when the workmen attempted to take the tortoise out she said: "Burn me rather than take me away from here." They respected her wishes and built her into the foundations; and since then women who suffer from the back-ache have only to come and sit on the bench above the well to be cured.

The actual mosque, or "praying-hall," is said to be formed of a rectangle or double cube of 90 metres by 45, and this vast space is equally divided by rows of horseshoe arches resting on whitewashed piers on which the lower part is swathed in finely patterned matting from Salé. Fifteen monumental doorways lead into the mosque. Their doors are of cedar, heavily barred and ornamented with wrought iron, and one of them bears the name of the artisan, and the date 531 of the Hegira (the first half of the twelfth century). The mosque also contains the two halls of audience of the Cadi, of which one has a graceful exterior façade with coupled lights under horseshoe arches; the library, whose 20,000 volumes are reported to have dwindled to about a thousand, the chapel where the Masters of the Koran recite the sacred text in fulfilment of pious bequests; the "museum" in the upper part of the minaret, wherein a remarkable collection of ancient astronomical instruments is said to be preserved; and the mestonda, or raised hall above the court, where women come to pray.
