Better bury gold in the embankments, than put it in ornaments on the stations. Will a single traveller be willing to pay an increased fare on the South Western, because the columns of the terminus are covered with patterns from Nineveh? He will only care less for the Ninevite ivories in the British Museum: or on the North Western, because there are old English-looking spandrils to the roof of the station at Crewe? He will only have less pleasure in their prototypes at Crewe House. Railroad architecture has or would have a dignity of its own if it were only left to its work. You would not put rings on the fingers of a smith at his anvil.

XXII. It is not however only in these marked situations that the abuse of which I speak takes place. There is hardly, at present, an application of ornamental work, which is not in some sort liable to blame of the same kind. We have a bad habit of trying to disguise disagreeable necessities by some form of sudden decoration, which is, in all other places, a.s.sociated with such necessities. I will name only one instance, that to which I have alluded before--the roses which conceal the ventilators in the flat roofs of our chapels. Many of those roses are of very beautiful design, borrowed from fine works: all their grace and finish are invisible when they are so placed, but their general form is afterwards a.s.sociated with the ugly buildings in which they constantly occur; and all the beautiful roses of the early French and English Gothic, especially such elaborate ones as those of the triforium of Coutances, are in consequence deprived of their pleasurable influence: and this without our having accomplished the smallest good by the use we have made of the dishonored form. Not a single person in the congregation ever receives one ray of pleasure from those roof roses; they are regarded with mere indifference, or lost in the general impression of harsh emptiness.

XXIII. Must not beauty, then, it will be asked, be sought for in the forms which we a.s.sociate with our every-day life? Yes, if you do it consistently, and in places where it can be calmly seen; but not if you use the beautiful form only as a mask and covering of the proper conditions and uses of things, nor if you thrust it into the places set apart for toil. Put it in the drawing-room, not into the workshop; put it upon domestic furniture, not upon tools of handicraft. All men have sense of what is right in this manner, if they would only use and apply that sense; every man knows where and how beauty gives him pleasure, if he would only ask for it when it does so, and not allow it to be forced upon him when he does not want it. Ask any one of the pa.s.sengers over London Bridge at this instant whether he cares about the forms of the bronze leaves on its lamps, and he will tell you, No. Modify these forms of leaves to a less scale, and put them on his milk-jug at breakfast, and ask him whether he likes them, and he will tell you, Yes. People have no need of teaching if they could only think and speak truth, and ask for what they like and want, and for nothing else: nor can a right disposition of beauty be ever arrived at except by this common sense, and allowance for the circ.u.mstances of the time and place. It does not follow, because bronze leaf.a.ge is in bad taste on the lamps of London Bridge, that it would be so on those of the Ponte della Trinita; nor, because it would be a folly to decorate the house fronts of Gracechurch Street, that it would be equally so to adorn those of some quiet provincial town. The question of greatest external or internal decoration depends entirely on the conditions of probable repose. It was a wise feeling which made the streets of Venice so rich in external ornament, for there is no couch of rest like the gondola. So, again, there is no subject of street ornament so wisely chosen as the fountain, where it is a fountain of use; for it is just there that perhaps the happiest pause takes place in the labor of the day, when the pitcher is rested on the edge of it, and the breath of the bearer is drawn deeply, and the hair swept from the forehead, and the uprightness of the form declined against the marble ledge, and the sound of the kind word or light laugh mixes with the trickle of the falling water, heard shriller and shriller as the pitcher fills. What pause is so sweet as that--so full of the depth of ancient days, so softened with the calm of pastoral solitude?

XXIV. II. Thus far, then, of the place for beauty. We were next to inquire into the characters which fitted it peculiarly for architectural appliance, and into the principles of choice and of arrangement which best regulate the imitation of natural forms in which it consists. The full answering of these questions would be a treatise on the art of design: I intend only to say a few words respecting the two conditions of that art which are essentially architectural,--Proportion and Abstraction. Neither of these qualities is necessary, to the same extent, in other fields of design. The sense of proportion is, by the landscape painter, frequently sacrificed to character and accident; the power of abstraction to that of complete realisation. The flowers of his foreground must often be unmeasured in their quant.i.ty, loose in their arrangement: what is calculated, either in quant.i.ty or disposition, must be artfully concealed. That calculation is by the architect to be prominently exhibited. So the abstraction of few characteristics out of many is shown only in the painter's sketch; in his finished work it is concealed or lost in completion. Architecture, on the contrary, delights in Abstraction and fears to complete her forms. Proportion and Abstraction, then, are the two especial marks of architectural design as distinguished from all other. Sculpture must have them in inferior degrees; leaning, on the one hand, to an architectural manner, when it is usually greatest (becoming, indeed, a part of Architecture), and, on the other, to a pictorial manner, when it is apt to lose its dignity, and sink into mere ingenious carving.

XXV. Now, of Proportion so much has been written, that I believe the only facts which are of practical use have been overwhelmed and kept out of sight by vain acc.u.mulations of particular instances and estimates.

Proportions are as infinite (and that in all kinds of things, as severally in colors, lines, shades, lights, and forms) as possible airs in music: and it is just as rational an attempt to teach a young architect how to proportion truly and well by calculating for him the proportions of fine works, as it would be to teach him to compose melodies by calculating the mathematical relations of the notes in Beethoven's Adelade or Mozart's Requiem. The man who has eye and intellect will invent beautiful proportions, and cannot help it; but he can no more tell _us_ how to do it than Wordsworth could tell us how to write a sonnet, or than Scott could have told us how to plan a romance.

But there are one or two general laws which can be told: they are of no use, indeed, except as preventives of gross mistake, but they are so far worth telling and remembering; and the more so because, in the discussion of the subtle laws of proportion (which will never be either numbered or known), architects are perpetually forgetting and transgressing the very simplest of its necessities.

XXVI. Of which the first is, that wherever Proportion exists at all, one member of the composition must be either larger than, or in some way supreme over, the rest. There is no proportion between equal things.

They can have symmetry only, and symmetry without proportion is not composition. It is necessary to perfect beauty, but it is the least necessary of its elements, nor of course is there any difficulty in obtaining it. Any succession of equal things is agreeable; but to compose is to arrange unequal things, and the first thing to be done in beginning a composition is to determine which is to be the princ.i.p.al thing. I believe that all that has been written and taught about proportion, put together, is not to the architect worth the single rule, well enforced, "Have one large thing and several smaller things, or one princ.i.p.al thing and several inferior things, and bind them well together." Sometimes there may be a regular gradation, as between the heights of stories in good designs for houses; sometimes a monarch with a lowly train, as in the spire with its pinnacles: the varieties of arrangement are infinite, but the law is universal--have one thing above the rest, either by size, or office, or interest. Don't put the pinnacles without the spire. What a host of ugly church towers have we in England, with pinnacles at the corners, and none in the middle! How many buildings like King's College Chapel at Cambridge, looking like tables upside down, with their four legs in the air! What! it will be said, have not beasts four legs? Yes, but legs of different shapes, and with a head between them. So they have a pair of ears: and perhaps a pair of horns: but not at both ends. Knock down a couple of pinnacles at either end in King's College Chapel, and you will have a kind of proportion instantly. So in a cathedral you may have one tower in the centre, and two at the west end; or two at the west end only, though a worse arrangement: but you must not have two at the west and two at the east end, unless you have some central member to connect them; and even then, buildings are generally bad which have large balancing features at the extremities, and small connecting ones in the centre, because it is not easy then to make the centre dominant. The bird or moth may indeed have wide wings, because the size of the wing does not give supremacy to the wing. The head and life are the mighty things, and the plumes, however wide, are subordinate. In fine west fronts with a pediment and two towers, the centre is always the princ.i.p.al ma.s.s, both in bulk and interest (as having the main gateway), and the towers are subordinated to it, as an animal's horns are to its head. The moment the towers rise so high as to overpower the body and centre, and become themselves the princ.i.p.al ma.s.ses, they will destroy the proportion, unless they are made unequal, and one of them the leading feature of the cathedral, as at Antwerp and Strasburg. But the purer method is to keep them down in due relation to the centre, and to throw up the pediment into a steep connecting ma.s.s, drawing the eye to it by rich tracery. This is n.o.bly done in St. Wulfran of Abbeville, and attempted partly at Rouen, though that west front is made up of so many unfinished and supervening designs that it is impossible to guess the real intention of any one of its builders.

[Ill.u.s.tration: PLATE X.--(Page 122--Vol. V.) TRACERIES AND MOULDINGS FROM ROUEN AND SALISBURY.]

XXVII. This rule of supremacy applies to the smallest as well as to the leading features: it is interestingly seen in the arrangement of all good mouldings. I have given one, on the opposite page, from Rouen cathedral; that of the tracery before distinguished as a type of the n.o.blest manner of Northern Gothic (Chap. II. -- XXII.). It is a tracery of three orders, of which the first is divided into a leaf moulding, fig. 4, and _b_ in the section, and a plain roll, also seen in fig. 4, _c_ in the section; these two divisions surround the entire window or panelling, and are carried by two-face shafts of corresponding sections.

The second and third orders are plain rolls following the line of the tracery; four divisions of moulding in all: of these four, the leaf moulding is, as seen in the sections, much the largest; next to it the outer roll; then, by an exquisite alternation, the innermost roll (_e_), in order that it may not be lost in the recess and the intermediate (_d_), the smallest. Each roll has its own shaft and capital; and the two smaller, which in effect upon the eye, owing to the retirement of the innermost, are nearly equal, have smaller capitals than the two larger, lifted a little to bring them to the same level. The wall in the trefoiled lights is curved, as from _e_ to _f_ in the section; but in the quatrefoil it is flat, only thrown back to the full depth of the recess below so as to get a sharp shadow instead of a soft one, the mouldings falling back to it in nearly a vertical curve behind the roll _e_. This could not, however, be managed with the simpler mouldings of the smaller quatrefoil above, whose half section is given from _g_ to g_2; but the architect was evidently fretted by the heavy look of its circular foils as opposed to the light spring of the arches below: so he threw its cusps obliquely clear from the wall, as seen in fig. 2, attached to it where they meet the circle, but with their finials pushed out from the natural level (_h_, in the section) to that of the first order (g_2) and supported by stone props behind, as seen in the profile fig. 2, which I got from the correspondent panel on the b.u.t.tress face (fig. 1 being on its side), and of which the lower cusps, being broken away, show the remnant of one of their props projecting from the wall. The oblique curve thus obtained in the profile is of singular grace. Take it all in all, I have never met with a more exquisite piece of varied, yet severe, proportioned and general arrangement (though all the windows of the period are fine, and especially delightful in the subordinate proportioning of the smaller capitals to the smaller shafts). The only fault it has is the inevitable misarrangement of the central shafts; for the enlargement of the inner roll, though beautiful in the group of four divisions at the side, causes, in the triple central shaft, the very awkwardness of heavy lateral members which has just been in most instances condemned. In the windows of the choir, and in most of the period, this difficulty is avoided by making the fourth order a fillet which only follows the foliation, while the three outermost are nearly in arithmetical progression of size, and the central triple shaft has of course the largest roll in front. The moulding of the Palazzo Foscari (Plate VIII., and Plate IV. fig. 8) is, for so simple a group, the grandest in effect I have even seen: it is composed of a large roll with two subordinates.

XXVIII. It is of course impossible to enter into details of instances belonging to so intricate division of our subject, in the compa.s.s of a general essay. I can but rapidly name the chief conditions of right.

Another of these is the connection of Symmetry with horizontal, and of Proportion with vertical, division. Evidently there is in symmetry a sense not merely of equality, but of balance: now a thing cannot be balanced by another on the top of it, though it may by one at the side of it. Hence, while it is not only allowable, but often necessary, to divide buildings, or parts of them, horizontally into halves, thirds, or other equal parts, all vertical divisions of this kind are utterly wrong; worst into half, next worst in the regular numbers which more betray the equality. I should have thought this almost the first principle of proportion which a young architect was taught: and yet I remember an important building, recently erected in England, in which the columns are cut in half by the projecting architraves of the central windows; and it is quite usual to see the spires of modern Gothic churches divided by a band of ornament half way up. In all fine spires there are two bands and three parts, as at Salisbury. The ornamented portion of the tower is there cut in half, and allowably, because the spire forms the third ma.s.s to which the other two are subordinate: two stories are also equal in Giotto's campanile, but dominant over smaller divisions below, and subordinated to the n.o.ble third above. Even this arrangement is difficult to treat; and it is usually safer to increase or diminish the height of the divisions regularly as they rise, as in the Doge's Palace, whose three divisions are in a bold geometrical progression: or, in towers, to get an alternate proportion between the body, the belfry, and the crown, as in the campanile of St. Mark's. But, at all events, get rid of equality; leave that to children and their card houses: the laws of nature and the reason of man are alike against it, in arts, as in politics. There is but one thoroughly ugly tower in Italy that I know of, and that is so because it is divided into vertical equal parts: the tower of Pisa.[12]

XXIX. One more principle of Proportion I have to name, equally simple, equally neglected. Proportion is between three terms at _least_. Hence, as the pinnacles are not enough without the spire, so neither the spire without the pinnacles. All men feel this and usually express their feeling by saying that the pinnacles conceal the junction of the spire and tower. This is one reason; but a more influential one is, that the pinnacles furnish the third term to the spire and tower. So that it is not enough, in order to secure proportion, to divide a building unequally; it must be divided into at least three parts; it may be into more (and in details with advantage), but on a large scale I find three is about the best number of parts in elevation, and five in horizontal extent, with freedom of increase to five in the one case and seven in the other; but not to more without confusion (in architecture, that is to say; for in organic structure the numbers cannot be limited). I purpose, in the course of works which are in preparation, to give copious ill.u.s.trations of this subject, but I will take at present only one instance of vertical proportion, from the flower stem of the common water plantain, _Alisma Plantago_. Fig. 5, Plate XII. is a reduced profile of one side of a plant gathered at random; it is seen to have five masts, of which, however, the uppermost is a mere shoot, and we can consider only their relations up to the fourth. Their lengths are measured on the line A B, which is the actual length of the lowest ma.s.s _a b_, A C=_b c_, A D=_c d_, and A E=_d e_. If the reader will take the trouble to measure these lengths and compare them, he will find that, within half a line, the uppermost A E=5/7 of A D, A D=6/8 of A C, and A C=7/9 of A B; a most subtle diminishing proportion. From each of the joints spring three major and three minor branches, each between each; but the major branches, at any joint, are placed over the minor branches at the joint below, by the curious arrangement of the joint itself--the stem is bluntly triangular; fig. 6 shows the section of any joint. The outer darkened triangle is the section of the lower stem; the inner, left light, of the upper stem; and the three main branches spring from the ledges left by the recession. Thus the stems diminish in diameter just as they diminish in height. The main branches (falsely placed in the profile over each other to show their relations) have respectively seven, six, five, four, and three arm-bones, like the masts of the stem; these divisions being proportioned in the same subtle manner. From the joints of these, it seems to be the _plan_ of the plant that three major and three minor branches should again spring, bearing the flowers: but, in these infinitely complicated members, vegetative nature admits much variety; in the plant from which these measures were taken the full complement appeared only at one of the secondary joints.

The leaf of this plant has five ribs on each side, as its flower generally five masts, arranged with the most exquisite grace of curve; but of lateral proportion I shall rather take ill.u.s.trations from architecture: the reader will find several in the accounts of the Duomo at Pisa and St. Mark's at Venice, in Chap. V. ---- XIV.-XVI. I give these arrangements merely as ill.u.s.trations, not as precedents: all beautiful proportions are unique, they are not general formulae.

x.x.x. The other condition of architectural treatment which we proposed to notice was the abstraction of imitated form. But there is a peculiar difficulty in touching within these narrow limits on such a subject as this, because the abstraction of which we find examples in existing art, is partly involuntary; and it is a matter of much nicety to determine where it begins to be purposed. In the progress of national as well as of individual mind, the first attempts at imitation are always abstract and incomplete. Greater completion marks the progress of art, absolute completion usually its decline; whence absolute completion of imitative form is often supposed to be in itself wrong. But it is not wrong always, only dangerous. Let us endeavor briefly to ascertain wherein its danger consists, and wherein its dignity.

x.x.xI. I have said that all art is abstract in its beginnings; that is to say, it expresses only a small number of the qualities of the thing represented. Curved and complex lines are represented by straight and simple ones; interior markings of forms are few, and much is symbolical and conventional. There is a resemblance between the work of a great nation, in this phase, and the work of childhood and ignorance, which, in the mind of a careless observer, might attach something like ridicule to it. The form of a tree on the Ninevite sculptures is much like that which, come twenty years ago, was familiar upon samplers; and the types of the face and figure in early Italian art are susceptible of easy caricature. On the signs which separate the infancy of magnificent manhood from every other, I do not pause to insist (they consist entirely in the choice of the symbol and of the features abstracted); but I pa.s.s to the next stage of art, a condition of strength in which the abstraction which was begun in incapability is continued in free will. This is the case, however, in pure sculpture and painting, as well as in architecture; and we have nothing to do but with that greater severity of manner which fits either to be a.s.sociated with the more realist art. I believe it properly consists only in a due expression of their subordination, an expression varying according to their place and office. The question is first to be clearly determined whether the architecture is a frame for the sculpture, or the sculpture an ornament of the architecture. If the latter, then the first office of that sculpture is not to represent the things it imitates, but to gather out of them those arrangements of form which shall be pleasing to the eye in their intended places. So soon as agreeable lines and points of shade have been added to the mouldings which were meagre, or to the lights which were unrelieved, the architectural work of the imitation is accomplished; and how far it shall be wrought towards completeness or not, will depend upon its place, and upon other various circ.u.mstances.

If, in its particular use or position, it is symmetrically arranged, there is, of course, an instant indication of architectural subjection.

But symmetry is not abstraction. Leaves may be carved in the most regular order, and yet be meanly imitative; or, on the other hand, they may be thrown wild and loose, and yet be highly architectural in their separate treatment. Nothing can be less symmetrical than the group of leaves which join the two columns in Plate XIII.; yet, since nothing of the leaf character is given but what is necessary for the bare suggestion of its image and the attainment of the lines desired, their treatment is highly abstract. It shows that the workman only wanted so much of the leaf as he supposed good for his architecture, and would allow no more; and how much is to be supposed good, depends, as I have said, much more on place and circ.u.mstance than on general laws. I know that this is not usually thought, and that many good architects would insist on abstraction in all cases: the question is so wide and so difficult that I express my opinion upon it most diffidently; but my own feeling is, that a purely abstract manner, like that of our earliest English work, does not afford room for the perfection of beautiful form, and that its severity is wearisome after the eye has been long accustomed to it. I have not done justice to the Salisbury dog-tooth moulding, of which the effect is sketched in fig. 5, Plate X., but I have done more justice to it nevertheless than to the beautiful French one above it; and I do not think that any candid reader would deny that, piquant and spirited as is that from Salisbury, the Rouen moulding is, in every respect, n.o.bler. It will be observed that its symmetry is more complicated, the leaf.a.ge being divided into double groups of two lobes each, each lobe of different structure. With exquisite feeling, one of these double groups is alternately omitted on the other side of the moulding (not seen in the Plate, but occupying the cavetto of the section), thus giving a playful lightness to the whole; and if the reader will allow for a beauty in the flow of the curved outlines (especially on the angle), of which he cannot in the least judge from my rude drawing, he will not, I think, expect easily to find a n.o.bler instance of decoration adapted to the severest mouldings.

Now it will be observed, that there is in its treatment a high degree of abstraction, though not so conventional as that of Salisbury: that is to say, the leaves have little more than their flow and outline represented; they are hardly undercut, but their edges are connected by a gentle and most studied curve with the stone behind; they have no serrations, no veinings, no rib or stalk on the angle, only an incision gracefully made towards their extremities, indicative of the central rib and depression. The whole style of the abstraction shows that the architect could, if he had chosen, have carried the imitation much farther, but stayed at this point of his own free will; and what he has done is also so perfect in its kind, that I feel disposed to accept his authority without question, so far as I can gather it from his works, on the whole subject of abstraction.

x.x.xII. Happily his opinion is frankly expressed. This moulding is on the lateral b.u.t.tress, and on a level with the top of the north gate; it cannot therefore be closely seen except from the wooden stairs of the belfry; it is not intended to be so seen, but calculated for a distance of, at least, forty to fifty feet from the eye. In the vault of the gate itself, half as near again, there are three rows of mouldings, as I think, by the same designer, at all events part of the same plan. One of them is given in Plate I. fig. 2 _a_. It will be seen that the abstraction is here infinitely less; the ivy leaves have stalks and a.s.sociated fruit, and a rib for each lobe, and are so far undercut as to detach their forms from the stone; while in the vine-leaf moulding above, of the same period, from the south gate, serration appears added to other purely imitative characters. Finally, in the animals which form the ornaments of the portion of the gate which is close to the eye, abstraction nearly vanishes into perfect sculpture.

x.x.xIII. Nearness to the eye, however, is not the only circ.u.mstance which influences architectural abstraction. These very animals are not merely better cut because close to the eye; they are put close to the eye that they may, without indiscretion, be better cut, on the n.o.ble principle, first I think, clearly enunciated by Mr. Eastlake, that the closest imitation shall be of the n.o.blest object. Farther, since the wildness and manner of growth of vegetation render a bona fide imitation of it impossible in sculpture--since its members must be reduced in number, ordered in direction, and cut away from their roots, even under the most earnestly imitative treatment,--it becomes a point, as I think, of good judgment, to proportion the completeness of execution of parts to the formality of the whole; and since five or six leaves must stand for a tree, to let also five or six touches stand for a leaf. But since the animal generally admits of perfect outline--since its form is detached, and may be fully represented, its sculpture may be more complete and faithful in all its parts. And this principle will be actually found. I believe, to guide the old workmen. If the animal form be in a gargoyle, incomplete, and coining out of a block of stone, or if a head only, as for a boss or other such partial use, its sculpture will be highly abstract. But if it be an entire animal, as a lizard, or a bird, or a squirrel, peeping among leaf.a.ge, its sculpture will be much farther carried, and I think, if small, near the eye, and worked in a fine material, may rightly be carried to the utmost possible completion.

Surely we cannot wish a less finish bestowed on those which animate the mouldings of the south door of the cathedral of Florence; nor desire that the birds in the capitals of the Doge's palace should be stripped of a single plume.

x.x.xIV. Under these limitations, then, I think that perfect sculpture may be made a part of the severest architecture; but this perfection was said in the outset to be dangerous. It is so in the highest degree; for the moment the architect allows himself to dwell on the imitated portions, there is a chance of his losing sight of the duty of his ornament, of its business as a part of the composition, and sacrificing its points of shade and effect to the delight of delicate carving. And then he is lost. His architecture has become a mere framework for the setting of delicate sculpture, which had better be all taken down and put into cabinets. It is well, therefore, that the young architect should be taught to think of imitative ornament as of the extreme of grace in language; not to be regarded at first, not to be obtained at the cost of purpose, meaning, force, or conciseness, yet, indeed, a perfection--the least of all perfections, and yet the crowning one of all--one which by itself, and regarded in itself, is an architectural c.o.xcombry, but is yet the sign of the most highly-trained mind and power when it is a.s.sociated with others. It is a safe manner, as I think, to design all things at first in severe abstraction, and to be prepared, if need were, to carry them out in that form; then to mark the parts where high finish would be admissible, to complete these always with stern reference to their general effect, and then connect them by a graduated scale of abstraction with the rest. And there is one safeguard against danger in this process on which I would finally insist. Never imitate anything but natural forms, and those the n.o.blest, in the completed parts. The degradation of the cinque cento manner of decoration was not owing to its naturalism, to its faithfulness of imitation, but to its imitation of ugly, i.e. unnatural things. So long as it restrained itself to sculpture of animals and flowers, it remained n.o.ble. The balcony, on the opposite page, from a house in the Campo St. Benedetto at Venice, shows one of the earliest occurrences of the cinque cento arabesque, and a fragment of the pattern is given in Plate XII. fig. 8.

It is but the arresting upon the stone work of a stem or two of the living flowers, which are rarely wanting in the window above (and which, by the by, the French and Italian peasantry often trellis with exquisite taste about their cas.e.m.e.nts). This arabesque, relieved as it is in darkness from the white stone by the stain of time, is surely both beautiful and pure; and as long as the renaissance ornament remained in such forms it may be beheld with undeserved admiration. But the moment that unnatural objects were a.s.sociated with these, and armor, and musical instruments, and wild meaningless scrolls and curled shields, and other such fancies, became princ.i.p.al in its subjects, its doom was sealed, and with it that of the architecture of the world.

[Ill.u.s.tration: PLATE XI.--(Page 131--Vol. V.) BALCONY IN THE CAMPO, ST. BENEDETTO, VENICE.]

x.x.xV. III. Our final inquiry was to be into the use of color as a.s.sociated 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 n.o.bler 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.

x.x.xVI. 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 sh.e.l.l, 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 versa; and I think it would be well in general to carve all capitals and graceful ornaments in white marble, and so leave them.

x.x.xVII. 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 a.s.suredly, 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 sh.e.l.l, 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 peac.o.c.k'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.

x.x.xVIII. Now, why it should be that color is best seen under these circ.u.mstances I will not here endeavor to determine; nor whether the lesson we are to learn from it be that it is G.o.d'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.

x.x.xIX. 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 ma.s.ses of it, to zones, as in the rainbow and the zebra; cloudings and flamings, as in marble sh.e.l.ls 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 s.p.a.ces 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 quant.i.ties, infinite invention in their disposition: but, in all cases, their shape will be effective only as it determines their quant.i.ty, 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 ma.s.ses of ungainly shape, as t.i.tian; 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 peac.o.c.k plume. Any of these men would have looked with infinite disgust upon the leaf.a.ge 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 a.s.sociated 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 s.p.a.ciousness 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 b.a.l.l.s 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. Ba.s.so-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 a.s.sociated with architecture: primarily, and as most fit for such purpose, the mosaic, highly abstract in treatment, and introducing brilliant color in ma.s.ses; the Madonna of Torcello being, as I think, the n.o.blest type of the manner, and the Baptistery of Parma the richest: next, the purely decorative fresco, like that of the Arena Chapel; finally, the fres...o...b..coming princ.i.p.al, as in the Vatican and Sistine. But I cannot, with any safety, follow the principles of abstraction in this pictorial ornament; since the n.o.blest 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 n.o.ble 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 princ.i.p.al, 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 n.o.ble 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 s.p.a.ces 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 ill.u.s.trated 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), a.s.sociated 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 leaf.a.ge 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 n.o.ble 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 quant.i.ty 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 s.p.a.ce, 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 sh.e.l.l. 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 G.o.d'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 G.o.d 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."

CHAPTER V.

THE LAMP OF LIFE.

I. Among the countless a.n.a.logies by which the nature and relations of the human soul are ill.u.s.trated in the material creation, none are more striking than the impressions inseparably connected with the active and dormant states of matter. I have elsewhere endeavored to show, that no inconsiderable part of the essential characters of Beauty depended on the expression of vital energy in organic things, or on the subjection to such energy, of things naturally pa.s.sive and powerless. I need not here repeat, of what was then advanced, more than the statement which I believe will meet with general acceptance, that things in other respects alike, as in their substance, or uses, or outward forms, are n.o.ble or ign.o.ble in proportion to the fulness of the life which either they themselves enjoy, or of whose action they bear the evidence, as sea sands are made beautiful by their bearing the seal of the motion of the waters. And this is especially true of all objects which bear upon them the impress of the highest order of creative life, that is to say, of the mind of man: they become n.o.ble or ign.o.ble in proportion to the amount of the energy of that mind which has visibly been employed upon them. But most peculiarly and imperatively does the rule hold with respect to the creations of Architecture, which being properly capable of no other life than this, and being not essentially composed of things pleasant in themselves,--as music of sweet sounds, or painting of fair colors, but of inert substance,--depend, for their dignity and pleasurableness in the utmost degree, upon the vivid expression of the intellectual life which has been concerned in their production.
