is merely symmetrical and harmonious, that which is organic, concrete, essentially itself conclusive and varied. And because this is so men are forced to reflect over distinctions of determinating form, no less than the express emphasis to be made on certain aspects of form, which is wholly superfluous where the question is only one of a definite purpose to be attained. A beam, for example, is from one point of view that which is carried forward in a straight line; at the same time, however, it terminates at both extremes. In the same way a post which has to support either rafter or roof stands on the ground and reaches its terminating point where the rafter rests upon it. The architecture of service asserts distinctions of this kind and gives form to them by means of art; an organic design, on the contrary, such as a plant, or a human being, ay, whether we look at such above or below, but in any case throughout, has to be organically embodied, to be differentiated in the latter case consequently by feet and head, or in the former by roots and corona.
(_β_) Conversely symbolic architecture takes its point of departure more or less from organic forms of this kind, as we see is the case with sphinxes, memnons, and so forth; yet it is also unable wholly to exclude in its walls, doors, beams, obelisks, and the rest, the principle of the straight line and uniformity, and is generally obliged to accept the assistance of such principles appertinent to the genuine art of building as equality of size, interval of relative position, rectilinear progression of rows, in short, order and regularity when it proposes to place in a series and to set up in accordance with architectural design the colossal sculptured figures to which we have referred. By doing so it unites in itself both principles[68], whose union brings for result an architecture, the beauty of which is promoted along with the object to which it is subservient, albeit in the symbolic type these two aspects[69] still lie in separation side by side instead of being fused in unity.
(_γ_) We may therefore so conceive the transition that on the one side the art of building, hitherto self-subsistent in type, is forced to modify under scientific principles[70] the forms of organisms in the direction of regularity, and to pass into the province of proposed expediency; while conversely what is entirely such intended purpose in the form moves in opposition to the principle of the organic world.
Where these two extremes come together, and mutually pass into one another, we get what is really beautiful classic architecture.
We may recognize this union, as it actually arises, clearly in the transformation now introduced of that which we already have met with in the architecture which was anterior under the form of columns. In other words, it is true that from one point of view walls are necessary to make an enclosure; but walls, too, can stand up independent, as we have already proved with examples, without making the enclosure complete, to which a roofing, no less than an enclosure of the sides, essentially contributes. But a roofing of this kind has to be supported. The simplest way of doing this is by columns, whose essential and, at the same time exclusive, rationale consists here in being simply _supports._ For this reason walls are really a superfluity is so far as it is only a question of support. For supporting is a mechanical relation, and belongs to a province of gravity and its laws. And in this[71] gravity the weight of a particular body is concentrated in its point of gravity, and must be assisted at this centre in remaining horizontal without a fall. This is precisely what the column does, so that with it the power of support appears to be reduced to the minimum limit of exterior means to effect this. What a wall at great cost[72] effects, is equally effected by a few columns. It is a very beautiful characteristic of classic architecture not to set up more columns than are actually necessary to carry the weight of the rafter and that which reposes thereon. In genuine architecture columns, for purposes of mere decoration, are not truly beautiful. For the same reason also columns which stand up entirely alone do not perform their true function. No doubt triumphal columns have been erected, such as the famous ones in honour of Trajan and Napoleon: but these, too, are really but a pedestal for statues, and moreover covered with sculptured reliefs to commemorate and glorify the hero, whose image they carry. In the case of the column, then, it is of exceptional importance to see how in the course of architectural development it is compelled to divest itself of the concrete form of Nature before it can secure its more abstract form, the form, that is, which is as compatible with a definite object as it is with beauty.
(_αα_) Independent architecture, on account of the fact that it starts with organic images, makes use of human shapes, as, for example, we find in Egypt figures in some measure at least human, such as Memnons and the like, are utilized. This is, however, a mere superfluity, in so far, that is, as a definition of this character is not the true medium of support. We find among the Greeks that Caryatides are used in another mode and under a more severe obedience to rule to support superimposed weight, but such cannot be extensively employed. Moreover, we can only regard it as a misuse of the human form to crush it together under such burdens, and it is for this reason that Caryatides receive the character of the oppressed; their drapery suggests a state of slavery under which it is a degradation to carry such burdens.
(_ββ_) The more natural organic form for pillars and supports which have to bear a weight is consequently the tree, plant-life generally, a stem, a thin stalk which strives upwards in a vertical direction. The hole of a tree already carries of its own nature its crown of branches, the blade of corn the ear, the stem the flower. These forms, too, the Egyptian art of building, which has not as yet attained the liberty of viewing them in their abstract intension, borrows directly from Nature.
In this respect the grandiose quality which we discover in the style of Egyptian palaces or temples--the colossal proportions of its rows of columns, the huge number of them, and withal the imposing mutual relations of the entire structure, has ever filled the spectator with wonder and astonishment. In these colonnades we do not find that all columns have the same form; they alternate between one, two, or three types. Denon, in his work on the Egyptian expedition, has collected a great number of such types. The combined effect is not as yet any uniform shape based on abstract principles of selection; rather the foundation is the shape of an onion, a reed-like efflorescence of leaf from the bulb, or, in other examples, a compression together of the root-leaves according to the manner of several kinds of plant. From this base, then, the thin stem breaks upwards straight, or mounts as column with twisted coils, and the capital is also a separation of leaves from branches which suggests the process of a flower. The imitation, however, is not true to Nature, but the plant-like forms are drained off under the architectural impulse, and made to approximate to circular, geometrical, and regular forms, or straight lines, so that such columns, in their entirety, resemble what are usually described as arabesques.
(_γγ_) This is not the place to enter into a general discussion of the _arabesque_ for the reason that notionally it marks precisely the transition from the architecture which adopts as its basic form the natural organism to that which by its adoption of a more severe regularity is more strictly architectonic. When, however, the art of building has become free in its definitive character it relegates arabesques to the function of decoration and ornament. They are then preeminently forms of plants strained off, so to speak, or forms which originate from plants together with entwined forms of animals and human beings, or forms of animals in their passage over to plant-life.
In so far as they purport to authenticate a symbolical significance the transitional passage between the different spheres of the animal kingdom hold good for it. Apart from such an interpretation they are simply the play of the imagination in the selection, combination and articulation of the most diverse forms of Nature. For architectural ornamentation of this kind, in the invention of which the imagination finds scope for its activity in the most varied creations of every kind, not even excluding utensils and drapery, the fundamental determinant and type is this, that whether it be plants, leaves, flowers, or animals, all are made to approximate to the abstract figures of science, in other words the inorganic. For this reason we frequently find arabesques to be stiff, untrue to organic life; and it is on this account that they are not unfrequently condemned and art is blamed for the use of them. This is exceptionally true of painting, though Raphael himself did not scruple to paint arabesques in great profusion, characterized with the highest charm, nobility of feeling, variety, and grace. No doubt arabesques are an antithesis to nature, whether we compare them with organic forms or the rigid laws of mechanics; but an opposition of this kind is not merely a right of art generally, but even an obligation under which architecture is bound.
It is only by this means that living forms in other respects unfitted for the art of building are made adaptable to the truly architectural style and brought into harmony with it. Such an adaptability is offered in an exceptionally close degree by vegetable Nature, which is also in the East utilized to an extravagant extent in arabesques; in other words plants are not as yet individual objects which possess feeling, but naturally present themselves as adapted to architectural design, by virtue of the fact that they form coverings and protection against rain, sunlight, and wind, and, generally speaking, do not possess the free oscillation[73] of lines which breaks forth from the regularity of scientific conceptions[74]. Architecturally used the regularity of leaves already present is yet further subjected to rule in the definition of rondure and straight line, so that by this means everything which it is possible to regard as distortion, unnaturalness, or stiffness in the plant-forms is fundamentally to be considered as a transformation adapted to the requirements of what is genuinely architectural.
In some such way in the column the real art of building passes from that which is purely organic imitation to the definite purpose of scientific rule, and from this to a position which again approximates to the organic result. We find it necessary to draw attention to this twofold point of departure from the actual necessities and the purposeless self-subsistency of architecture, because the true type unites both principles. The beautiful column originates in the natural form, which is then transformed into the post, that is, it submits to the uniformity and scientific precision of form.
CHAPTER II CLASSICAL ARCHITECTURE The art of building, when it has attained the position peculiarly its own and adequate to its notional content is subservient in its products to an end, and a significance which it does not itself essentially possess. It becomes an inorganic environment, a whole that is co-ordinated and built conformably to the laws of gravity, whose configurations are subject to that which is severely regular, straight, rectangular, circular, the relations of definite number and quantity, that which is essentially limited measure and strict conformity to rule. Its beauty consists in this very relation to purpose, which, in its freedom from direct[75] admixture with what is organic, spiritual, and symbolical, and despite the fact that it subserves an end, nevertheless combines in an essentially exclusive totality, which suffers its own aim to appear through all its modifications, and in the harmonious co-ordination of its relations clothes that which is purely adapted to purpose in the forms of beauty. Architecture, however, at this stage[76] corresponds to its real notion, for the reason that it is not in a position to endow that which is in the most explicit sense spiritual with a fully adequate existence, and is consequently only able to inform what is external and devoid of spirit in its contrasted appearance with that which is spiritual.
We propose, in our consideration of this art of building, in which the relation of service is as truly a characteristic as that of beauty, to adopt the following course of argument.
In the _first_ instance we have to establish the _general notion_ and character of the same.
_Secondly_, we shall have to adduce the _particular_ fundamental determinants of the architectonic types which are deducible from the ulterior purpose which the classical work of art is erected to subserve.
_Thirdly_, we propose to survey the concrete reality which results from the development of classical architecture.
I do not, however, propose in discussing any of the above relations to enter into detail, but will limit myself to points of most general significance, a restriction more easy to observe in the present case than it was in that of the symbolical type of building.
1. THE GENERAL CHARACTER OF CLASSICAL ARCHITECTURE (_a_) In conformity with the principle I have already more than once adverted to the fundamental idea of the genuine art of building consists in this, that the spiritual import is not exclusively reposed in the work of construction itself, which by this means becomes an independent symbol of ideal signification[77], but, with the converse result, that this significance secures its free existence outside the limits of architecture. This existence may be of a twofold character, to the extent in other words that another art of extensive range--I refer, above all, to the art of sculpture of the true classical type--sets before us and gives independent form to the significance, or the individual man in himself receives and gives effect to the same in the active verity of his life. Apart from this[78], these two aspects may still appear together. When, therefore, the Oriental architecture of the Babylonians, Hindoos, and Egyptians, on the one hand, gave symbolical form, in images of independent consistency, to that which was reckoned among these people as the absolute and true, or, from another aspect, enclosed, despite its external natural form, that which was conserved after death--in contrast to this what we find now is--whether we regard it relatively to art's activity, or to the life of actual existence--that the spiritual is _separated_ from the work of construction in _independent guise_ for itself, and architecture becomes the _vassal_ of what is spiritual, which constitutes the real significance and the determinating end. This end is consequently predominant. It controls the entire work; it determines the fundamental form of the same no less than its external skeleton, and neither suffers the material nor the individual's imagination and caprice to assert their independence in a self-substantive way, as was the case in symbolical architecture, or to develop, over and beyond the true purpose of the work, a superfluity of manifold parts and configurations, as is the case in the romantic type.
(_b_) In considering a construction of this character we have, then, first to ask ourselves not merely what are the circumstances under which it was erected, but what is its aim and purpose. To make its construction compatible with such considerations, to have a due regard for climate, position, and the environing landscape, to create a whole, one in spontaneous co-ordination, by a regard for all these aspects as subservient to one purpose, this is the task stated broadly, in the entire fulfilment of which the instincts and genius of the artist will appear conspicuous. Among the Greeks we find that it is public buildings, temples, colonnades, and halls utilized for the ordinary rest and commerce of the day, approaches, such as the famous ascent of the Acropolis in Athens, which are pre-eminently the objects of the builder's art. Private residences, on the other hand, were of a very simple character. With the Romans, on the contrary, it is the luxurious character of private houses, especially villas, which becomes prominent; and we may say the same thing of imperial palaces, public baths, theatres, circuses, amphitheatres, aqueducts, and springs. Buildings of this type, however, the utility of which throughout remains the commanding and directing principle, are merely able to accept beauty in a more or less decorative sense. The object most compatible with freedom of treatment in this sphere is that of religion--the temple-house as the enclosure of an individual which itself is appropriated by fine art, and placed before us by sculpture as the statue of the god.
(_c_) In the pursuit of aims such as those above mentioned, then, genuine architecture appears to be more free than the symbolic type of the previous stage, which seizes on the organic forms from Nature, nay, more free than sculpture, which is compelled to accept the human form it finds, and unites itself with them and their general relations as presented it. Classical architecture rather invents its forms and their configuration, so far as the content is concerned, from ends of spiritual import and in respect to form from human reason without any prototype. This greater freedom must, in a relative sense, be admitted; but the province in which it is exercised remains restricted, and the treatment which belongs to the classical art of building, on account of the rationality[79] of its forms is, taken as a whole, somewhat of an abstract and dry character.
Frederich von Schlegel has described architecture as a frozen music; and in truth both these arts repose on a harmony of relations, which admit of being referred to number, and are consequently readily grasped in their fundamental characteristics. In our own case the fundamental determinant for these essential traits and their simple, more serious and imposing, or more charming and elegant relations is supplied by the dwelling-house, that is, walls, columns, beams brought together in the wholly crystalline forms of scientific deduction. What the relations are we are not permitted to reduce to the bare determinants of number and measure. But an oblong, quadrilateral figure with right angles is more pleasing than a square, because in the case of the oblong we are more thus affected both by equality and inequality[80]. If the one dimension, namely breadth, is half as large as the other, we have a relation which pleases; with an oblong which is long and narrow the reverse is the case. Along with this the mechanical relations of support and being supported must likewise be maintained in their genuine measure and law; a heavy entablature, for instance, cannot rest on slender and delicate columns, or conversely great structures be prepared in order after all to lay on them something very light. In all these mutual relations, such as that of the breadth to the length and height of the building, the height of the columns to their thickness, the intervals and number of the columns, the character and variety or simplicity of decorations, the size of many plinths, borders, and so forth, a secret principle of rhythm[81] prevails among the ancients, which the instinct of the Greeks before all others has discovered; from which he may no doubt now and again deviate in points of detail, but the fundamental relations of which he is in general bound to preserve in order that he may not fall away from beauty.
2. THE FUNDAMENTAL DETERMINANTS OF ARCHITECTURAL FORMS TAKEN SEVERALLY (_a_) We have already alluded to the old controversy whether the material of wood or stone is to be accepted as the point of departure in building, and whether also it is from this difference of material that the architectural types proceed. For the real art of building at least, in so far as it lays emphasis on the aspect of ultimate purpose and elaborates the fundamental type of the dwelling on the lines of beauty we may accept wood as the more original of the two.
This is the conclusion of Hirt, following in this respect Vitruvius, and his conclusion has been much disputed. I will in a few words offer my own view on the matter in dispute, In the ordinary course of such reflections we seek to discover the abstract and simple law for a concrete result assumed as already present. It is in this way that Hirt looks for the basic model of Greek buildings, in like manner the design[82], the anatomical framework, and finds it, so far as form and the material connected with it is concerned, in the dwelling and building of wood. No doubt a house as such is built mainly as a dwelling, a protection against storm, rain, weather, animals, and human beings, and requires an enclosure that is complete, in order that a family or a larger community of men may collect in independent seclusion and may look after their necessities and pursue their avocations in such seclusion. The house is a structure throughout with a definite purpose, a creation of mankind for human objects. For this reason we find him occupied upon it in many ways and with many objects, and the structure is articulated in an aggregate pile of all kinds of mechanical ways of mutual interlacement and imposition[83] in order to hold in position and secure, according to the laws of gravity, what men are compelled to look after, that is, the making stable what is erected[84], the closing it in, the support of what is superimposed, and not merely in the way of support, but, where the structure rests horizontally, the preservation of it in such a position, and, further, the uniting of all that clashes together at nooks and corners and so on. Now it is quite true that the house makes it necessary that the enclosure should be complete; and for this walls are most serviceable and safest; and from this point of view the building of stone appears most to answer the purpose. We may, however, with equal ease construct our fence with posts standing in juxtaposition, upon which then beams will rest, which at the same time both bind together and secure the perpendicular posts. Finally we come to the cover of all and roofing.
In the temple house, moreover, the fact of enclosure is not the main fact of importance, but the feature of support and being supported. For this mechanical result the wooden structure is obviously the nearest to hand and the most natural. For the post, as that which supports, which at the same time requires a means of conjunction, and suffers the same to weigh on it in the shape of the cross-beam, constitutes here all that goes to the root of the matter. This essential division of parts and connection as well as the association of these aspects for a definite purpose belongs to the very nature of a wooden structure, which has its necessary material directly supplied it by the tree. In the tree we find already, without working upon it to any considerable or laborious extent, both post and beam, in so far as, that is, the wood already by itself possesses a definite form and consists of separate lengths, more or less in the straight line, lengths which can be brought together into rectangular corners no less than those which are acute or obtuse, and in this way provide corner pillars, supports, cross-beams and roof. Stone, on the contrary, never at any time possesses a form so definite. In contrast to the tree it is a formless mass, which first must be intentionally isolated and worked upon, in order that it may fit in juxtaposition to or superposition on other pieces and so once more be brought together with such. It requires, in short, several processes before it receives the form and serviceableness which wood already possesses independently. Moreover, stone material, when it is used in great masses, invites rather excavations and generally speaking, being _ab initio_ relatively formless, is capable of every kind of form, for which reason it is rather the congenial material for the symbolical as also the romantic types of building, while wood, by reason of its natural form of straight stems, is demonstrably without mediation more serviceable to that more severe type of purpose and observance of rule, which is the fountain-head of classical architecture. In this respect the structure of stone is mainly predominant with the self-substantive type of building, although even among the Egyptians, in their colonnades bordered with plinths, other considerations supervene, which the structure of wood is able more readily and in the first instance to satisfy. Conversely we do not find that classical architecture restricts itself entirely to buildings of wood, but, on the contrary, where it is elaborated in conformity with beauty, executes its buildings in stone; but in such a way, however, that we are from a certain point of view still able to recognize in the architectural forms the original principle of the wood structure, if also from a further one definite relations attach which do not belong to that kind of building as such.
(_b_) The points of fundamental importance, which emphasize the dwelling-house as the basic type of the temple, may be in all essential particulars enumerated as follows. If we consider with closer attention the house in its mechanical relation to itself we shall find, in accordance with what we have already stated, on the one hand, masses of architectural form which serve as _support_ and, on the other, those that _are supported_ both being united for stability and security.
Thirdly, we have before us the definite aspect of enclosure and limitation according to the three dimensions of length, breadth, and height. A construction, moreover, which, by the fact of its being a mutual correlation of definite aspects distinct from each other, is a concrete whole, is bound to declare this unity in its constitution. So we find here that essential differences arise which perforce assert themselves no less in their division and specific elaboration than they do in their rational _connexus._ (_α_) Of first importance in this respect to consider is the aspect of service in the way of _support._ When we speak of masses that support we commonly, under the influence of every-day needs, think of the wall as the most secure and reliable means of support. Support as such, however, as we have already seen, is not the exclusive principle of the wall; for the wall serves essentially as a means of enclosure and connection, and for this reason is a predominant feature in the romantic type of building. What is the peculiarity of Greek architecture is this, that it gives direct form to the principle of support by itself, and for this object employs columns as a fundamental contribution to the purpose and beauty of its architecture.
(_αα_) The aim of the column is to support and only this; and although a series of columns set up in a straight line make a boundary, such an enclosure falls short of a secure wall or partition, and is, in fact, expressly cancelled by the genuine partition and placed in a position of free independence. Owing to this exclusive object of support which pertains to the column, it is of first importance that it should display the aspect of such a purpose relatively to the weight which rests upon it. Consequently it should neither be too strong nor too slender, nor again too compressed, not mount upwards to such a height and with such ease as though the weight upon it was not treated seriously.
(_ββ_) And just as this column is thus differentiated from the enclosing wall, or fence, it is further from another point of view distinct from the mere _post._ In other words, the post is fixed directly in the ground and ceases with like directness at the precise point where a weight is reposed upon it. For which reason its determinate length, its commencement and termination equally appear as a negative limitation by means of something else, as a determinacy which is the result of chance, which it does not possess in its own right. Commencement and termination, however, are defining characteristics, which are part of the very notion of the supporting column, and consequently must declare themselves in it as the conditions[85] of its own substance. This is the ground of the fact that architecture, in the elaboration of its beauty, assigns to the column a base and a capital. In the Tuscan order, no doubt, we find no base; the column springs immediately from the ground. This being so, however, the length appears to the vision as something accidental. We are ignorant whether the column has not been to some undefined extent driven into the soil by the superimposed weight. In order that its commencement must not expose this undefined and accidental appearance it must with intention have the foot assigned to it, on which it stands, and which expressly enables us to recognize the commencement as in reality such. Art will therefore affirm as part of its function that the column begins at a certain place and for the rest it will make the security, and stable subsistence obvious to the eyes, and set the vision at rest in this respect also. For similar reasons our column should terminate in a capital, which is quite as much evidence of the real function of being a support as it is an affirmation of the fact that the column terminates here. This conception of a commencement and conclusion which are both deliberate is what affords us, in fact, the profounder explanation of base and capital. An analogous case is that of a cadence in music, which requires a secure resolution, or that of a book which should terminate without a full stop, or should start off without a capital letter, in the making of which, however, especially in the Middle Ages, large illuminated letters have been employed, with similar decorations at the work's conclusion, in order to bring prominently before the mind the facts of commencement and termination. However much, therefore, both base and capital appear to exceed what is obviously required we must not regard them as a decorative superfluity, or think of simply deducing them from the example of Egyptian columns, which still imitate the type of the vegetable kingdom. Figures of organic design, such as are represented by sculpture in animal and human form, begin and terminate in the free outlines they themselves present, for it is the rational organism itself, which gives outline to the form working thereon from its own intrinsic nature. Architecture, on the contrary, possesses for the column and its shapes nothing beyond the mechanical relation of support, and the spatial distance from the ground to the point where the weight that is supported terminates the column. Art, however, is bound to emphasize and disclose the particular aspects which lie together in this determinate relation for the reason that they are essential features of the column. Its precise length and its twofold boundary both above and below, that is, no less than its relation as support, must consequently not appear as coming to it incidentally and by virtue of something else, but must also be represented as immanent in its very being.
With respect to the form of column other than its base and capital, it is in the first place round, circular-shaped, for it has to stand up in free and independent self-seclusion. The most essentially simple, securely exclusive, rationally defined[86], and most regular line is in fact the circle. For this reason the column already proves from its shape that it is not adapted to form an even surface when placed in adjacent rows, as is the case with adjacent posts which are squared to the rectangular corner, and so present walls and partitions, but it has merely the object to offer a support under its own self-limitation.
Moreover the columnar structure is ordinarily reduced in size gradually, as it ascends from one-third of its height, it becomes less in circumference and thickness, because the portions beneath have to carry that above, and it is felt necessary to emphasize and make obvious also this mechanical relation of the several parts of the column itself. Finally, we frequently find that columns are grooved; the reason of this is twofold, first, essentially to diversify the simple form, and secondly to make the columns appear more thick by means of such a division where this is necessary.
(_γγ_) Although, then, the column is set up in independent isolation it has none the less to make it appear evident that it is not placed there for its own sake, but as subservient to the mass which it is erected to support. In so far as the house requires a boundary on every side the singular column is therefore not sufficient, but others have to be placed adjacent to it, in other words we come upon the definite conception of a diversity of columns placed in a _series._ And when several columns support the same weight this common service is at the same time that which determines the equal height which they all possess and which unites them together, in other words the beam. This marks the transition from the aspect of support to the opposed object supported.
(_β_) That which columns support is the _entablature_ superimposed.
The relation of most importance to be considered here is that of _rectangularity._ Not merely in its relation to the ground, but also in that to the entablature the supporting structure must be rectangular.
For the horizontal position is by the laws of gravity that which is alone intrinsically the most stable and fitting, and the right angle the only definitely secure one. The acute and obtuse angles are, on the contrary, indefinite, and both vary in their degree and are subject to contingency.
We may differentiate between the component parts of the entablature as follows: (_αα_) The _architrave_, that is, the main beam, rests immediately upon the columns which stand adjacent in a direct line of equal height; this unites the columns together and places on them a weight shared equally. As beam, and nothing more, it merely requires the form of four level surfaces mutually related as rectangular in all three dimensions and their abstract regularity. Owing to the fact, however, that the architrave as to one part of it is supported by the columns, and in another constitutes the stay of the rest of the entablature, and it is from this latter again that itself receives the necessary relation
