XV. No limit: it is one of the affectations of architects to speak of overcharged ornament. Ornament cannot be overcharged if it be good, and is always overcharged when it is bad. I have given, on the opposite page (fig. 1), one of the smallest niches of the central gate of Rouen. That gate I suppose to be the most exquisite piece of pure flamboyant work existing; for though I have spoken of the upper portions, especially the receding window, as degenerate, the gate itself is of a purer period, and has hardly any renaissance taint. There are four strings of these niches (each with two figures beneath it) round the porch, from the ground to the top of the arch, with three intermediate rows of larger niches, far more elaborate; besides the six principal canopies of each outer pier. The total number of the subordinate niches alone, each worked like that in the plate, and each with a different pattern of traceries in each compartment, is one hundred and seventy-six.[4] Yet in all this ornament there is not one cusp, one finial that is useless--not a stroke of the chisel is in vain; the grace and luxuriance of it all are visible--sensible rather--even to the uninquiring eye; and all its minuteness does not diminish the majesty, while it increases the mystery, of the noble and unbroken vault. It is not less the boast of some styles that they can bear ornament, than of others that they can do without it; but we do not often enough reflect that those very styles, of so haughty simplicity, owe part of their pleasurableness to contrast, and would be wearisome if universal. They are but the rests and monotones of the art; it is to its far happier, far higher, exaltation that we owe those fair fronts of variegated mosaic, charged with wild fancies and dark hosts of imagery, thicker and quainter than ever filled the depth of midsummer dream; those vaulted gates, trellised with close leaves; those window-labyrinths of twisted tracery and starry light; those misty masses of multitudinous pinnacle and diademed tower; the only witnesses, perhaps that remain to us of the faith and fear of nations. All else for which the builders sacrificed, has passed away--all their living interests, and aims, and achievements. We know not for what they labored, and we see no evidence of their reward. Victory, wealth, authority, happiness--all have departed, though bought by many a bitter sacrifice. But of them, and their life, and their toil upon the earth, one reward, one evidence, is left to us in those gray heaps of deep-wrought stone. They have taken with them to the grave their powers, their honors, and their errors; but they have left us their adoration. CHAPTER II. THE LAMP OF TRUTH.
