Chapter LXXXVI: Section XLV: In the same way, whenever the subject of the sculpture was

definite, its color was of necessity definite also; and, in the hands of the Northern builders, it often became, in consequence, rather the means of explaining and animating the stories of their stone-work, than a matter of abstract decorative science. Flowers were painted red, trees green, and faces flesh-color; the result of the whole being often far more entertaining than beautiful. And also, though in the lines of the mouldings and the decorations of shafts or vaults, a richer and more abstract method of coloring was adopted (aided by the rapid development of the best principles of color in early glass-painting), the vigorous depths of shadow in the Northern sculpture confused the architect's eye, compelling him to use violent colors in the recesses, if these were to be seen as color at all, and thus injured his perception of more delicate color harmonies; so that in innumerable instances it becomes very disputable whether monuments even of the best times were improved by the color bestowed upon them, or the contrary. But, in the South, the flatness and comparatively vague forms of the sculpture, while they appeared to call for color in order to enhance their interest, presented exactly the conditions which would set it off to the greatest advantage; breadth or surface displaying even the most delicate tints in the lights, and faintness of shadow joining with the most delicate and pearly grays of color harmony; while the subject of the design being in nearly all cases reduced to mere intricacy of ornamental line, might be colored in any way the architect chose without any loss of rationality. Where oak-leaves and roses were carved into fresh relief and perfect bloom, it was necessary to paint the one green and the other red; but in portions of ornamentation where there was nothing which could be definitely construed into either an oak-leaf or a rose, but a mere labyrinth of beautiful lines, becoming here something like a leaf, and there something like a flower, the whole tracery of the sculpture might be left white, and grounded with gold or blue, or treated in any other manner best harmonizing with the colors around it. And as the necessarily feeble character of the sculpture called for and was ready to display the best arrangements of color, so the precious marbles in the architect's hands give him at once the best examples and the best means of color. The best examples, for the tints of all natural stones are as exquisite in quality as endless in change; and the best means, for they are all permanent.

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.
