Bourges, Paris, Troyes, and Clermont are the only cathedrals with double aisles about choir and nave. Bourges is exceptional in that the inner aisle is twice as high as the outer--so high that it possesses its own triforium and clearstory; so high that the pier arches around the middle church rise to more than half the height of the edifice. Indeed, many an English cathedral could stand under the pier arches of Bourges. Each pillar is encircled by eight shafts--an arrangement that accentuates its loftiness. It may be claimed that there is over-emphasis in a procession of such giant columns about the interior of a church, and that there is something spectacular in a colonnade of such stupendous arches. Certainly the main clearstory is dwarfed by comparison, and the contrast in height between inner and outer aisle is too violent. Bourges must pass as a superb experiment rather than the restrained achievement from which emanates a school. Subsequent architects preferred to take as model the more classic division of Amiens' interior wall elevation. None the less is this most original basilica magnificently and romantically beautiful. Upon entering the church for the first time one feels the gripping sensation of beholding a thing audacious and gigantic. And yet the impression conveyed is not that of overweening pride. There is reverence here. Bishop Durandus tells us that the piers of a church are the bishops and doctors who sustain the temple of God by their doctrines, that the length of a church representeth fortitude which patiently endureth till it attain heaven; its breadth, charity; its height, courage that despiseth prosperity and adversity, hoping to see the gladness of the Lord in the land of the living. The windows are hospitality with cheerfulness, and tenderness with charity. They are Holy Scriptures which expel the wind and the rain--that is, all things hurtful--but transmit the light of the true Sun--that is, God--into the hearts of the faithful.[132] So wrote the wise old XIII-century Midi bishop for whom the whole world and everything in it were symbols. Sound doctrine, fortitude, and warm protecting hospitality--such are qualities supremely understood of Bourges. There is awe in this church and there is magic. Of the boundless imagination of dreams are certain sunset aspects here, when from the wide western window of Jean de Berry gleams of light strike athwart these vast arches of wonderland, across these sixty big pillars of stone, and night-time hours--during the May evening services of Our Lady--when the great church as in fearsome meditation is shrouded in shadow.
