In a palace irregularity seems unpardonable. The architect has there practically unlimited command of funds and of his arrangements, and he can easily design his suites of rooms so as to produce any amount of uniformity he may require: the different heights of the different storeys and the amount of ornament on them, with the employment of wings for offices, is sufficient to mark the various purposes of the various parts; but where the system is carried so far in great public buildings, that great halls, libraries, committee-rooms, and subordinate residences are all squeezed into one perfectly uniform design, the building loses all meaning, and fails from the opposite error.
The rule seems to be, that every building or every part of one ought most distinctly and clearly to express not only its constructive exigencies, but also the uses for which it is destined; on the other hand, that mere utility, in all instances where architectural effect is aimed at, ought to give way to artistic requirements; and that an architect is consequently justified, in so far as his means will admit, in producing that amount of uniformity and regularity which seems indispensable for anything like grandeur of effect. In villas and small buildings all we look for is picturesqueness and meaning combined with elegance; but in larger and more monumental erections we expect something more; and this can hardly be obtained without the introduction of some new element which shall tell, in the first place, that artistic excellence was the ruling idea of the design, and in the next should give it that perfect balance and symmetry which seems to be as inherent a quality of the higher works of nature as of true art.
XV.—Imitation of Nature.
The subject of the imitation of Nature is one intimately connected with those mooted in the preceding paragraphs, and regarding which considerable misunderstanding seems to prevail. It is generally assumed that in architecture we ought to copy natural objects as we see them, whereas the truth seems to be that we ought always to copy the processes, never the forms of Nature. The error apparently has arisen from confounding together the imitative arts of painting and sculpture with the constructive art of architecture. The former have no other mode of expression than by copying, more or less literally, the forms of Nature; the latter, as explained above, depends wholly on a different class of elements for its effect; but at the same time no architect can either study too intently, or copy too closely, the methods and processes by which Nature accomplishes her ends; and the most perfect building will be that in which these have been most closely and literally followed.
To take one prominent instance:—So far as we can judge, the human body is the most perfect of Nature’s works; in it the groundwork of skeleton is never seen, and though it can hardly be said to be anywhere concealed, it is only displayed at the joints or more prominent points of support, where the action of the frame would be otherwise unintelligible. The muscles are disposed not only where they are most useful, but so as to form groups gracefully rounded in outline. The softness and elegance of these are further aided by the deposition of adipose matter, and the whole is covered with a skin which with its beautiful texture conceals the more utilitarian construction of the internal parts. In the trunk of the body the viscera are disposed wholly without symmetry or reference to beauty of any sort—the heart on one side, the liver on the other, and the other parts exactly in those positions and in those forms by which they may most directly and easily perform the essential functions for which they are designed. But the whole is concealed in a perfectly symmetrical sheath of the most exquisitely beautiful outline. It may be safely asserted that a building is beautiful and perfect exactly in the ratio in which the same amount of concealment and the same amount of display of construction is preserved, where the same symmetry is shown as between the right and left sides of the human body—the same difference as between the legs and arms, where the parts are applied to different purposes, and where the same amount of ornament is added, to adorn without interfering with what is useful. In short, there is no principle involved in the structure of man which may not be taken as the most absolute standard of excellence in architecture.
It is in Nature’s highest works that we find the symmetry of proportion most prominent. When we descend to the lower types of animals we lose it to a great extent, and among trees and vegetables generally find it only in a far less degree, and sometimes miss it altogether. In the mineral kingdom among rocks and stones it is altogether absent. So universal is this principle in Nature that we may safely apply it to our criticism on art, and say that a building is perfect as a whole in proportion to its motived regularity, and departs from the highest type in the ratio in which symmetrical arrangement is neglected. It may, however, be incorrect to say that an oak-tree is a less perfect work of creation than a human being, but it is certain that it is lower in the scale of created beings. So it may be said that a picturesque group of Gothic buildings may be as perfect as the stately regularity of an Egyptian or classic temple; but if it is so, it is equally certain that it belongs to a lower and inferior class of design.
This analogy, however, we may leave for the present. The one point which it is indispensable to insist on here is, that man can progress or tend towards success only by following the principles and copying, so far as he can understand them, the processes which Nature employs in her works; but he can never succeed in anything by copying forms without reference to principles. If we could find Nature making trees like stones, or animals like trees, or birds like fishes, or fishes like mammalia, or using any parts taken from one kingdom for purposes belonging to another, it would then be perfectly legitimate for us to use man’s stature as the modulus for a Doric, or woman’s as that of an Ionic column—to build cathedrals like groves, and make windows like leaves, or to estimate their beauty by their resemblance to such objects; but all such comparisons proceed on an entire mistake of what imitation of Nature really means.
It is the merest and most absolute negation of reason to apply to one purpose things that were designed for another, or to imitate them when they have no appropriateness; but it is our highest privilege to understand the processes of Nature. To apply these to our own wants and purposes is the noblest use of human intellect and the perfection of human wisdom.
So instinctively, but so literally, has this correct process of imitating Nature been followed in all true styles of architecture, that we can always reason regarding them as we do with reference to natural objects. Thus, if an architect finds in any quarter of the globe a Doric or Corinthian capital with a few traces of a foundation, he can, at a glance, tell the age of the temple or building to which it belonged. He knows who the people were who erected it, to what purpose it was dedicated, and proceeds at once to restore its porticos, and without much uncertainty can reproduce the whole fabric. Or if he finds a few Gothic bases in situ, with a few mouldings or frusta of columns, by the same process he traces the age, the size, and the purposes of the building before him. A Cuvier or an Owen can restore the form and predicate the habits of an extinct animal from a few fragments of bone, or even from a print of a foot. In the same manner an architect may, from a few fragments of a building, if of a true style of architecture, restore the whole of its pristine forms, and with almost the same amount of certainty. This arises wholly because the architects of former days had correct ideas of what was meant by imitation of Nature. They added nothing to their buildings which was not essential; there was no detail which had not its use, and no ornament which was not an elaboration or heightening of some essential part, and hence it is that a true building is as like to a work of Nature as any production of man’s hands can be to the creations of his Maker.
