exactly the conditions which would set it off to the greatest advantage; breadth of surface displaying even the most delicate tints in the lights, and faintness of shadow joining with the most delicate and pearly greys 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.
§ 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 naïveté 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.
§ 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.
§ XLVIII. The due consideration of the principles above stated will enable the traveller to judge with more candor and justice of the architecture of St. Mark’s than usually it would have been possible for him to do while under the influence of the prejudices necessitated by familiarity with the very different schools of Northern art. I wish it were in my power to lay also before the general reader some exemplification of the manner in which these strange principles are developed in the lovely building. But exactly in proportion to the nobility of any work, is the difficulty of conveying a just impression of it; and wherever I have occasion to bestow high praise, there it is exactly most dangerous for me to endeavor to illustrate my meaning, except by reference to the work itself. And, in fact, the principal reason why architectural criticism is at this day so far behind all other, is the impossibility of illustrating the best architecture faithfully. Of the various schools of painting, examples are accessible to every one, and reference to the works themselves is found sufficient for all purposes of criticism; but there is nothing like St. Mark’s or the Ducal Palace to be referred to in the National Gallery, and no faithful illustration of them is possible on the scale of such a volume as this. And it is exceedingly difficult on any scale. Nothing is so rare in art, as far as my own experience goes, as a fair illustration of architecture; perfect illustration of it does not exist. For all good architecture depends upon the adaptation of its chiselling to the effect at a certain distance from the eye; and to render the peculiar confusion in the midst of order, and uncertainty in the midst of decision, and mystery in the midst of trenchant lines, which are the result of distance, together with perfect expression of the peculiarities of the design, requires the skill of the most admirable artist, devoted to the work with the most severe conscientiousness, neither the skill nor the determination having as yet been given to the subject. And in the illustration of details, every building of any pretensions to high architectural rank would require a volume of plates, and those finished with extraordinary care. With respect to the two buildings which are the principal subjects of the present volume, St. Mark’s and the Ducal Palace, I have found it quite impossible to do them the slightest justice by any kind of portraiture; and I abandoned the endeavor in the case of the latter with less regret, because in the new Crystal Palace (as the poetical public insist upon calling it, though it is neither a palace, nor of crystal) there will be placed, I believe, a noble cast of one of its angles. As for St. Mark’s, the effort was hopeless from the beginning. For its effect depends not only upon the most delicate sculpture in every part, but, as we have just stated, eminently on its color also, and that the most subtle, variable, inexpressible color in the world,—the color of glass, of transparent alabaster, of polished marble, and lustrous gold. It would be easier to illustrate a crest of Scottish mountain, with its purple heather and pale harebells at their fullest and fairest, or a glade of Jura forest, with its floor of anemone and moss, than a single portico of St. Mark’s. The fragment of one of its archivolts, given at the bottom of the opposite Plate, is not to illustrate the thing itself, but to illustrate the impossibility of illustration.
§ XLIX. It is left a fragment, in order to get it on a larger scale; and yet even on this scale it is too small to show the sharp folds and points of the marble vine-leaves with sufficient clearness. The ground of it is gold, the sculpture in the spandrils is not more than an inch and a half deep, rarely so much. It is in fact nothing more than an exquisite sketching of outlines in marble, to about the same depth as in the Elgin frieze; the draperies, however, being filled with close folds, in the manner of the Byzantine pictures, folds especially necessary here, as large masses could not be expressed in the shallow sculpture without becoming insipid; but the disposition of these folds is always most beautiful, and often opposed by broad and simple spaces, like that obtained by the scroll in the hand of the prophet, seen in the plate.
VI.
THE VINE TREE, AND IN SERVICE.
The balls in the archivolt project considerably, and the interstices between their interwoven bands of marble are filled with colors like the illuminations of a manuscript; violet, crimson, blue, gold, and green alternately: but no green is ever used without an intermixture of blue pieces in the mosaic, nor any blue without a little centre of pale green; sometimes only a single piece of glass a quarter of an inch square, so subtle was the feeling for color which was thus to be satisfied.32 The intermediate circles have golden stars set on an azure ground, varied in the same manner; and the small crosses seen in the intervals are alternately blue and subdued scarlet, with two small circles of white set in the golden ground above and beneath them, each only about half an inch across (this work, remember, being on the outside of the building, and twenty feet above the eye), while the blue crosses have each a pale green centre. Of all this exquisitely mingled hue, no plate, however large or expensive, could give any adequate conception; but, if the reader will supply in imagination to the engraving what he supplies to a common woodcut of a group of flowers, the decision of the respective merits of modern and of Byzantine
The fact is, that no two tesseræ of the glass are exactly of the same tint, the greens being all varied with blues, the blues of different depths, the reds of different clearness, so that the effect of each mass of color is full of variety, like the stippled color of a fruit piece.
