It is difficult, in describing the architecture of Morocco, to avoid producing an impression of monotony.  The ground-plan of mosques and Medersas is always practically the same, and the same elements, few in number and endlessly repeated, make up the materials and the form of the ornament.  The effect upon the eye is not monotonous, for a patient art has infinitely varied the combinations of pattern and the juxtapositions of color; while the depth of undercutting of the stucco, and the treatment of the bronze doors and of the carved cedar corbels, necessarily varies with the periods which produced them.

But in the Saadian mausoleum a new element has been introduced which makes this little monument a thing apart.  The marble columns supporting the roof appear to be unique in Moroccan architecture, and they lend themselves to a new roof-plan which relates the building rather to the tradition of Venice or Byzantine by way of Kairouan and Cordova.

The late date of the monument precludes any idea of a direct artistic tradition.  The most probable explanation seems to be that the architect of the mausoleum was familiar with European Renaissance architecture, and saw the beauty to be derived from using precious marbles not merely as ornament, but in the Roman and Italian way, as a structural element.  Panels and fountain-basins are ornament, and ornament changes nothing essential in architecture; but when, for instance, heavy square piers are replaced by detached columns, a new style results.

It is not only the novelty of its plan that makes the Saadian mausoleum singular among Moroccan monuments.  The details of its ornament are of the most intricate refinement:  it seems as though the last graces of the expiring Merinid art had been gathered up into this rare blossom.  And the slant of sunlight on lustrous columns, the depths of fretted gold, the dusky ivory of the walls and the pure white of the cenotaphs, so classic in spareness of ornament and simplicity of design—­this subtle harmony of form and color gives to the dim rich chapel an air of dream-like unreality.

And how can it seem other than a dream?  Who can have conceived, in the heart of a savage Saharan camp, the serenity and balance of this hidden place?  And how came such fragile loveliness to survive, preserving, behind a screen of tumbling walls, of nettles and offal and dead beasts, every curve of its traceries and every cell of its honeycombing?

Such questions inevitably bring one back to the central riddle of the mysterious North African civilization:  the perpetual flux and the immovable stability, the barbarous customs and sensuous refinements, the absence of artistic originality and the gift for regrouping borrowed motives, the patient and exquisite workmanship and the immediate neglect and degradation of the thing once made.
