SECTION XLVI. Every motive thus concurred in urging him to the study of chromatic decoration, and every advantage was given him in the pursuit of it; and this at the very moment when, as presently to be noticed, the _naivete_ of barbaric Christianity could only be forcibly appealed to by the help of colored pictures: so that, both externally and internally, the architectural construction became partly merged in pictorial effect; and the whole edifice is to be regarded less as a temple wherein to pray, than as itself a Book of Common Prayer, a vast illuminated missal, bound with alabaster instead of parchment, studded with porphyry pillars instead of jewels, and written within and without in letters of enamel and gold. SECTION XLVII. LAW VII. _That the impression of the architecture is not to be dependent on size._ And now there is but one final consequence to be deduced. The reader understands, I trust, by this time, that the claims of these several parts of the building upon his attention will depend upon their delicacy of design, their perfection of color, their preciousness of material, and their legendary interest. All these qualities are independent of size, and partly even inconsistent with it. Neither delicacy of surface sculpture, nor subtle gradations of color, can be appreciated by the eye at a distance; and since we have seen that our sculpture is generally to be only an inch or two in depth, and that our coloring is in great part to be produced with the soft tints and veins of natural stones, it will follow necessarily that none of the parts of the building can be removed far from the eye, and therefore that the whole mass of it cannot be large. It is not even desirable that it should be so; for the temper in which the mind addresses itself to contemplate minute and beautiful details is altogether different from that in which it submits itself to vague impressions of space and size. And therefore we must not be disappointed, but grateful, when we find all the best work of the building concentrated within a space comparatively small; and that, for the great cliff-like buttresses and mighty piers of the North, shooting up into indiscernible height, we have here low walls spread before us like the pages of a book, and shafts whose capitals we may touch with our hand.
