The Seven Lamps of Architecture

XXXV. III. Our final inquiry was to be into the use of color as associated with architectural ornament.

I do not feel able to speak with any confidence respecting the touching of sculpture with color. I would only note one point, that sculpture is the representation of an idea, while architecture is itself a real thing. The idea may, as I think, be left colorless, and colored by the beholder's mind: but a reality ought to have reality in all its attributes: its color should be as fixed as its form. I cannot, therefore, consider architecture as in any wise perfect without color. Farther, as I have above noticed, I think the colors of architecture should be those of natural stones; partly because more durable, but also because more perfect and graceful. For to conquer the harshness and deadness of tones laid upon stone or on gesso, needs the management and discretion of a true painter; and on this co-operation we must not calculate in laying down rules for general practice. If Tintoret or Giorgione are at hand, and ask us for a wall to paint, we will alter our whole design for their sake, and become their servants; but we must, as architects, expect the aid of the common workman only; and the laying of color by a mechanical hand, and its toning under a vulgar eye, are far more offensive than rudeness in cutting the stone. The latter is imperfection only; the former deadness or discordance. At the best, such color is so inferior to the lovely and mellow hues of the natural stone, that it is wise to sacrifice some of the intricacy of design, if by so doing we may employ the nobler material. And if, as we looked to Nature for instruction respecting form, we look to her also to learn the management of color, we shall, perhaps, find that this sacrifice of intricacy is for other causes expedient.

XXXVI. First, then, I think that in making this reference we are to consider our building as a kind of organized creature; in coloring which we must look to the single and separately organized creatures of Nature, not to her landscape combinations. Our building, if it is well composed, is one thing, and is to be colored as Nature would color one thing—a shell, a flower, or an animal; not as she colors groups of things.

And the first broad conclusion we shall deduce from observance of natural color in such cases will be, that it never follows form, but is arranged on an entirely separate system. What mysterious connection there may be between the shape of the spots on an animal's skin and its anatomical system, I do not know, nor even if such a connection has in any wise been traced: but to the eye the systems are entirely separate, and in many cases that of color is accidentally variable. The stripes of a zebra do not follow the lines of its body or limbs, still less the spots of a leopard. In the plumage of birds, each feather bears a part of the pattern which is arbitrarily carried over the body, having indeed certain graceful harmonies with the form, diminishing or enlarging in directions which sometimes follow, but also not unfrequently oppose, the directions of its muscular lines. Whatever harmonies there may be, are distinctly like those of two separate musical parts, coinciding here and there only—never discordant, but essentially different I hold this, then, for the first great principle of architectural color. Let it be visibly independent of form. Never paint a column with vertical lines, but always cross it.13 Never give separate mouldings separate colors (I know this is heresy, but I never shrink from any conclusions, however contrary to human authority, to which I am led by observance of natural principles); and in sculptured ornaments I do not paint the leaves or figures (I cannot help the Elgin frieze) of one color and their ground of another, but vary both the ground and the figures with the same harmony. Notice how Nature does it in a variegated flower; not one leaf red and another white, but a point of red and a zone of white, or whatever it may be, to each. In certain places you may run your two systems closer, and here and there let them be parallel for a note or two, but see that the colors and the forms coincide only as two orders of mouldings do; the same for an instant, but each holding its own course. So single members may sometimes have single colors: as a bird's head is sometimes of one color and its shoulders another, you may make your capital of one color and your shaft another; but in general the best place for color is on broad surfaces, not on the points of interest in form. An animal is mottled on its breast and back, rarely on its paws or about its eyes; so put your variegation boldly on the flat wall and broad shaft, but be shy of it in the capital and moulding; in all cases it is a safe rule to simplify color when form is rich, and vice versâ; and I think it would be well in general to carve all capitals and graceful ornaments in white marble, and so leave them.

XXXVII. Independence then being first secured, what kind of limiting outlines shall we adopt for the system of color itself?

I am quite sure that any person familiar with natural objects will never be surprised at any appearance of care or finish in them. That is the condition of the universe. But there is cause both for surprise and inquiry whenever we see anything like carelessness or incompletion: that is not a common condition; it must be one appointed for some singular purpose. I believe that such surprise will be forcibly felt by any one who, after studying carefully the lines of some variegated organic form, will set himself to copy with similar diligence those of its colors. The boundaries of the forms he will assuredly, whatever the object, have found drawn with a delicacy and precision which no human hand can follow. Those of its colors he will find in many cases, though governed always by a certain rude symmetry, yet irregular, blotched, imperfect, liable to all kinds of accidents and awkwardnesses. Look at the tracery of the lines on a camp shell, and see how oddly and awkwardly its tents are pitched. It is not indeed always so: there is occasionally, as in the eye of the peacock's plume, an apparent precision, but still a precision far inferior to that of the drawing of the filaments which bear that lovely stain; and in the plurality of cases a degree of looseness and variation, and, still more singularly, of harshness and violence in arrangement, is admitted in color which would be monstrous in form. Observe the difference in the precision of a fish's scales and of the spots on them.

XXXVIII. Now, why it should be that color is best seen under these circumstances I will not here endeavor to determine; nor whether the lesson we are to learn from it be that it is God's will that all manner of delights should never be combined in one thing. But the fact is certain, that color is always by Him arranged in these simple or rude forms, and as certain that, therefore, it must be best seen in them, and that we shall never mend by refining its arrangements. Experience teaches us the same thing. Infinite nonsense has been written about the union of perfect color with perfect form. They never will, never can be united. Color, to be perfect, must have a soft outline or a simple one: it cannot have a refined one; and you will never produce a good painted window with good figure-drawing in it. You will lose perfection of color as you give perfection of line. Try to put in order and form the colors of a piece of opal.

XXXIX. I conclude, then, that all arrangements of color, for its own sake, in graceful forms, are barbarous; and that, to paint a color pattern with the lovely lines of a Greek leaf moulding, is an utterly savage procedure. I cannot find anything in natural color like this: it is not in the bond. I find it in all natural form—never in natural color. If, then, our architectural color is to be beautiful as its form was, by being imitative, we are limited to these conditions—to simple masses of it, to zones, as in the rainbow and the zebra; cloudings and flamings, as in marble shells and plumage, or spots of various shapes and dimensions. All these conditions are susceptible of various degrees of sharpness and delicacy, and of complication in arrangement. The zone may become a delicate line, and arrange itself in chequers and zig-zags. The flaming may be more or less defined, as on a tulip leaf, and may at last be represented by a triangle of color, and arrange itself in stars or other shapes; the spot may be also graduated into a stain, or defined into a square or circle. The most exquisite harmonies may be composed of these simple elements: some soft and full of flushed and melting spaces of color; others piquant and sparkling, or deep and rich, formed of close groups of the fiery fragments: perfect and lovely proportion may be exhibited in the relation of their quantities, infinite invention in their disposition: but, in all cases, their shape will be effective only as it determines their quantity, and regulates their operation on each other; points or edges of one being introduced between breadths of others, and so on. Triangular and barred forms are therefore convenient, or others the simplest possible; leaving the pleasure of the spectator to be taken in the color, and in that only. Curved outlines, especially if refined, deaden the color, and confuse the mind. Even in figure painting the greatest colorists have either melted their outline away, as often Correggio and Rubens; or purposely made their masses of ungainly shape, as Titian; or placed their brightest hues in costume, where they could get quaint patterns, as Veronese, and especially Angelico, with whom, however, the absolute virtue of color is secondary to grace of line. Hence, he never uses the blended hues of Correggio, like those on the wing of the little Cupid, in the "Venus and Mercury," but always the severest type—the peacock plume. Any of these men would have looked with infinite disgust upon the leafage and scrollwork which form the ground of color in our modern painted windows, and yet all whom I have named were much infected with the love of renaissance designs. We must also allow for the freedom of the painter's subject, and looseness of his associated lines; a pattern being severe in a picture, which is over luxurious upon a building. I believe, therefore, that it is impossible to be over quaint or angular in architectural coloring; and thus many dispositions which I have had occasion to reprobate in form, are, in color, the best that can be invented. I have always, for instance, spoken with contempt of the Tudor style, for this reason, that, having surrendered all pretence to spaciousness and breadth,—having divided its surfaces by an infinite number of lines, it yet sacrifices the only characters which can make lines beautiful; sacrifices all the variety and grace which long atoned for the caprice of the Flamboyant, and adopts, for its leading feature, an entanglement of cross bars and verticals, showing about as much invention or skill of design as the reticulation of the bricklayer's sieve. Yet this very reticulation would in color be highly beautiful; and all the heraldry, and other features which, in form, are monstrous, may be delightful as themes of color (so long as there are no fluttering or over-twisted lines in them); and this observe, because, when colored, they take the place of a mere pattern, and the resemblance to nature, which could not be found in their sculptured forms, is found in their piquant variegation of other surfaces. There is a beautiful and bright bit of wall painting behind the Duomo of Verona, composed of coats of arms, whose bearings are balls of gold set in bars of green (altered blue?) and white, with cardinal's hats in alternate squares. This is of course, however, fit only for domestic work. The front of the Doge's palace at Venice is the purest and most chaste model that I can name (but one) of the fit application of color to public buildings. The sculpture and mouldings are all white; but the wall surface is chequered with marble blocks of pale rose, the chequers being in no wise harmonized, or fitted to the forms of the windows; but looking as if the surface had been completed first, and the windows cut out of it. In Plate XII. fig. 2 the reader will see two of the patterns used in green and white, on the columns of San Michele of Lucca, every column having a different design. Both are beautiful, but the upper one certainly the best. Yet in sculpture its lines would have been perfectly barbarous, and those even of the lower not enough refined.

XL. Restraining ourselves, therefore, to the use of such simple patterns, so far forth as our color is subordinate either to architectural structure, or sculptural form, we have yet one more manner of ornamentation to add to our general means of effect, monochrome design, the intermediate condition between coloring and carving. The relations of the entire system of architectural decoration may then be thus expressed.

1. Organic form dominant. True, independent sculpture, and alto-relievo; rich capitals, and mouldings; to be elaborate in completion of form, not abstract, and either to be left in pure white marble, or most cautiously touched with color in points and borders only, in a system not concurrent with their forms.

2. Organic form sub-dominant. Basso-relievo or intaglio. To be more abstract in proportion to the reduction of depth; to be also more rigid and simple in contour; to be touched with color more boldly and in an increased degree, exactly in proportion to the reduced depth and fulness of form, but still in a system non-concurrent with their forms.

3. Organic form abstracted to outline. Monochrome design, still farther reduced to simplicity of contour, and therefore admitting for the first time the color to be concurrent with its outlines; that is to say, as its name imports, the entire figure to be detached in one color from a ground of another.

4. Organic forms entirely lost. Geometrical patterns or variable cloudings in the most vivid color.

On the opposite side of this scale, ascending from the color pattern, I would place the various forms of painting which may be associated with architecture: primarily, and as most fit for such purpose, the mosaic, highly abstract in treatment, and introducing brilliant color in masses; the Madonna of Torcello being, as I think, the noblest type of the manner, and the Baptistery of Parma the richest: next, the purely decorative fresco, like that of the Arena Chapel; finally, the fresco becoming principal, as in the Vatican and Sistine. But I cannot, with any safety, follow the principles of abstraction in this pictorial ornament; since the noblest examples of it appear to me to owe their architectural applicability to their archaic manner; and I think that the abstraction and admirable simplicity which render them fit media of the most splendid coloring, cannot be recovered by a voluntary condescension. The Byzantines themselves would not, I think, if they could have drawn the figure better, have used it for a color decoration; and that use, as peculiar to a condition of childhood, however noble and full of promise, cannot be included among those modes of adornment which are now legitimate or even possible. There is a difficulty in the management of the painted window for the same reason, which has not yet been met, and we must conquer that first, before we can venture to consider the wall as a painted window on a large scale. Pictorial subject, without such abstraction, becomes necessarily principal, or, at all events, ceases to be the architect's concern; its plan must be left to the painter after the completion of the building, as in the works of Veronese and Giorgione on the palaces of Venice.

XLI. Pure architectural decoration, then, may be considered as limited to the four kinds above specified; of which each glides almost imperceptibly into the other. Thus, the Elgin frieze is a monochrome in a state of transition to sculpture, retaining, as I think, the half-cast skin too long. Of pure monochrome, I have given an example in Plate VI., from the noble front of St. Michele of Lucca. It contains forty such arches, all covered with equally elaborate ornaments, entirely drawn by cutting out their ground to about the depth of an inch in the flat white marble, and filling the spaces with pieces of green serpentine; a most elaborate mode of sculpture, requiring excessive care and precision in the fitting of the edges, and of course double work, the same line needing to be cut both in the marble and serpentine. The excessive simplicity of the forms will be at once perceived; the eyes of the figures of animals, for instance, being indicated only by a round dot, formed by a little inlet circle of serpentine, about half an inch over: but, though simple, they admit often much grace of curvature, as in the neck of the bird seen above the right hand pillar.14 The pieces of serpentine have fallen out in many places, giving the black shadows, as seen under the horseman's arm and bird's neck, and in the semi-circular line round the arch, once filled with some pattern. It would have illustrated my point better to have restored the lost portions, but I always draw a thing exactly as it is, hating restoration of any kind; and I would especially direct the reader's attention to the completion of the forms in the sculptured ornament of the marble cornices, as opposed to the abstraction of the monochrome figures, of the ball and cross patterns between the arches, and of the triangular ornament round the arch on the left.

XLII. I have an intense love for these monochrome figures, owing to their wonderful life and spirit in all the works on which I found them; nevertheless, I believe that the excessive degree of abstraction which they imply necessitates our placing them in the rank of a progressive or imperfect art, and that a perfect building should rather be composed of the highest sculpture (organic form dominant and sub-dominant), associated with pattern colors on the flat or broad surfaces. And we find, in fact, that the cathedral of Pisa, which is a higher type than that of Lucca, exactly follows this condition, the color being put in geometrical patterns on its surfaces, and animal-forms and lovely leafage used in the sculptured cornices and pillars. And I think that the grace of the carved forms is best seen when it is thus boldly opposed to severe traceries of color, while the color itself is, as we have seen, always most piquant when it is put into sharp angular arrangements. Thus the sculpture is approved and set off by the color, and the color seen to the best advantage in its opposition both to the whiteness and the grace of the carved marble.

XLIII. In the course of this and the preceding chapters, I have now separately enumerated most of the conditions of Power and Beauty, which in the outset I stated to be the grounds of the deepest impressions with which architecture could affect the human mind; but I would ask permission to recapitulate them in order to see if there be any building which I may offer as an example of the unison, in such manner as is possible, of them all. Glancing back, then, to the beginning of the third chapter, and introducing in their place the conditions incidentally determined in the two previous sections, we shall have the following list of noble characters:

Considerable size, exhibited by simple terminal lines (Chap. III. § 6). Projection towards the top (§ 7). Breadth of flat surface (§ 8). Square compartments of that surface (§ 9). Varied and visible masonry (§ 11). Vigorous depth of shadow (§ 13), exhibited especially by pierced traceries (§ 18). Varied proportion in ascent (Chap. IV. § 28). Lateral symmetry (§ 28). Sculpture most delicate at the base (Chap. I. § 12). Enriched quantity of ornament at the top (§ 13). Sculpture abstract in inferior ornaments and mouldings (Chap. IV. § 31), complete in animal forms (§ 33). Both to be executed in white marble (§ 40). Vivid color introduced in flat geometrical patterns (§ 39), and obtained by the use of naturally colored stone (§ 35).

These characteristics occur more or less in different buildings, some in one and some in another. But all together, and all in their highest possible relative degrees, they exist, as far as I know, only in one building in the world, the Campanile of Giotto at Florence. The drawing of the tracery of its upper story, which heads this chapter, rude as it is, will nevertheless give the reader some better conception of that tower's magnificence than the thin outlines in which it is usually portrayed. In its first appeal to the stranger's eye there is something unpleasing; a mingling, as it seems to him, of over severity with over minuteness. But let him give it time, as he should to all other consummate art. I remember well how, when a boy, I used to despise that Campanile, and think it meanly smooth and finished. But I have since lived beside it many a day, and looked out upon it from my windows by sunlight and moonlight, and I shall not soon forget how profound and gloomy appeared to me the savageness of the Northern Gothic, when I afterwards stood, for the first time, beneath the front of Salisbury. The contrast is indeed strange, if it could be quickly felt, between the rising of those grey walls out of their quiet swarded space, like dark and barren rocks out of a green lake, with their rude, mouldering, rough-grained shafts, and triple lights, without tracery or other ornament than the martins' nests in the height of them, and that bright, smooth, sunny surface of glowing jasper, those spiral shafts and fairy traceries, so white, so faint, so crystalline, that their slight shapes are hardly traced in darkness on the pallor of the Eastern sky, that serene height of mountain alabaster, colored like a morning cloud, and chased like a sea shell. And if this be, as I believe it, the model and mirror of perfect architecture, is there not something to be learned by looking back to the early life of him who raised it? I said that the Power of human mind had its growth in the Wilderness; much more must the love and the conception of that beauty, whose every line and hue we have seen to be, at the best, a faded image of God's daily work, and an arrested ray of some star of creation, be given chiefly in the places which He has gladdened by planting there the fir tree and the pine. Not within the walls of Florence, but among the far away fields of her lilies, was the child trained who was to raise that headstone of Beauty above the towers of watch and war. Remember all that he became; count the sacred thoughts with which he filled the heart of Italy; ask those who followed him what they learned at his feet; and when you have numbered his labors, and received their testimony, if it seem to you that God had verily poured out upon this His servant no common nor restrained portion of His Spirit, and that he was indeed a king among the children of men, remember also that the legend upon his crown was that of David's:—"I took thee from the sheepcote, and from following the sheep."
