(b) Beginning with examples such as the above of a movement towards external objects, sculpture proceeds further in the representation of situations, conflicts, and actions yet more involved with motion, and at last arrives at the group. For with an increase of specific detail in the action we have placed before us the more concrete animation, which expands in contradiction, reactions, and thereby, too, in the presence of several figures essentially related and intertwined with each other.
(α) At first we have, however, merely tranquil juxtapositions, such as, for example, the two colossal horse-tamers, which are set up in Rome on Mount Cavallo, and indicate Castor and Pollux. The one statue is commonly ascribed to Pheidias, the other to Praxiteles. There is, however, no strong evidence for this, although the extraordinary excellence of conception, and the no less exquisite thoroughness of the execution justifies names as famous. Such are entirely independent groups, which as yet express no real action, or the result of it, and are wholly appropriate as representations of sculpture and public exposition before the Parthenon, where it appears they were originally placed.
(β) Sculpture, however, is equally occupied in the group with the presentment of situations, which have as their content conflicts, discordant actions, pain, and other similar conditions. In this direction, too, we can only speak highly of the genuine artistic insight of the Greeks, which did not set forth such groups independently, and by themselves, but brought them, for the reason that sculpture has already made a departure from its peculiar, that is to say its self-subsistent, province, into closer relation to architecture. The temple figure, that is the isolated statue, stood in unimpaired tranquillity and sacredness within the inner shrine. The external pediment, on the contrary, was decorated with groups which represented definite actions of the god, and consequently admitted of more animated movement in its elaboration. The famous group of Niobe and her children is of this type. The general form for the co-ordination of each part is determined by the space which the group in question had to fill. The principal figure stood in the middle, and was thus able to be the largest in size and most prominent. The rest according as they were placed in the direction of the acute angle of the gable-end had to submit to other postures, the limit being reached by that of a reclining figure.
Of other famous works I will here only mention the Laocoon group. It has now for over forty years been the object of much inquiry and controversy. In particular it has been regarded as a matter of real importance, whether Virgil in his description followed this work of sculpture, or the sculptor adopted his work to the scene depicted by Virgil, whether Laocoon here is actually crying out, and whether it is appropriate in a work of sculpture to attempt to express such a cry, and many more criticisms of this kind. Critics have worried themselves up and down with such matters of psychological interest for the simple reason that they have not as yet secured the sort of enthusiasm and critical acumen which Winckelmann possessed; and, moreover, arm-chair professors are more readily disposed for such investigations for the reason that not unfrequently they have neither the opportunity granted them to see real works of art, nor the capacity to grasp them for what they are when they do so. The most essential thing which can occupy our attention in this group is this namely, that in the supreme pain, the supreme truth, the convulsive tension of the body, the distention of all the muscles, the noble aspect of beauty is still preserved, and the process has not been carried in the remotest degree to the extremes of grimace, distortion, and over-strain. Despite of this, however, the entire work belongs without doubt—we have only to consider its subject-matter, the artificiality of its co-ordinate grouping, the disposition of each posed figure and the type of its elaboration—to a much later period, which already seeks to pass beyond simple beauty and vitality by means of a deliberate obtrusion of science in the configuration and muscular development of the human body, and no less is anxious to please by refined excess in its executive elaboration. The step from the ingenuous ease and greatness of art to a mere mannerism is already taken.
(γ) Works of sculpture may be set forth in very various places, such as in the entrances to columned halls, forecourts, landings of staircases, niches, and so forth. It is just in this variety of local position and architectural setting, which, on its account too, is variously related to human circumstances and conditions, that the content and object of such works of art are for ever changing, approaching as such art does in the group yet more closely our humanity. It is, however, a serious defect to place groups that embody much movement and variety of figure on the top of a building without further background against the sky. In other words the colour of the sky may sometimes be gray, at others blue and dazzlingly bright, so that it is impossible to see the outlines of the figures. Yet these outlines, that is, the silhouette we find in them, is just what is most important; it is the main thing which we recognize, and which simply makes the rest intelligible. For in the case of a group we find that many portions stand in front relatively to others, an arm before the trunk of the body, or one leg in front of another. Now the fact of distance alone disturbs the clearness and intelligible articulation of such parts, or at least tends to do this more emphatically than in the case of outlined portions which are independent. We have only to imagine a group depicted on a piece of paper in which certain parts of a figure are strongly and sharply indicated, while others on the contrary are marked with lines of less defined and arresting definition. This is precisely the effect of a statue's lines, and yet more those of groups, which have no other background but that of the sky; in the latter case we only see a sharply indicated silhouette, in which, so far as what is within the compass of that outline, only relatively weaker articulation is visible.
This is the reason that, to take an example near home, the Victory on the Brandenburg gate in Berlin not only affects us strongly by virtue of its simplicity and repose, but can be readily followed through its separate figures. The horses, in fact, stand far from each other, without either of them impairing the view of the other; and similarly the figure of Victory rises sufficiently high above them. Conversely the Apollo drawn in a car by griffins, which we have on the Opera House, is less satisfactory from this point of view, however artistic the entire conception and technical work may be in other respects. By the favour of a friend I saw these figures before they were taken from the workshop. The effect promised was noble. But as we see them now at such a height, we have far too much of one outline partly obscuring another, which in its turn is backed by something else, and consequently is less freely and clearly silhouetted than would be the case were all the figures silhouetted in their simple outlines[187]. The griffins, which necessarily, on account of their shorter legs, do not stand up either so highly or so freely as horses, have wings into the bargain, and Apollo, too, has his tuft of hair and his lyre. All this detail is too much for the position, and only tends to make the outlines obscure.
(c) The final mode of representation, in which sculpture makes an important step in the direction of the principle of painting is the relief; in the first instance the high-relief, and after it the low-relief. The condition here is the surface, the figures standing on one and the same plane, so that the spatial totality of the figure, which is the point of departure of sculpture, more and more tends to disappear. The older form of relief, however, does not as yet approximate so closely to painting, which involves distinctions of perspective between the foreground and background, but rather holds fast to the surface or plane as such without permitting the different objects to project into or to retire within the distinctions of their spatial position by means of an artificial reduction of size. In the present case figures in profile are preferred, and they are placed side by side on an even surface. A simple treatment of this kind does not admit the content of complicated actions, but actions which in real life already adopt more or less of one and the same line of motion, processions of all kinds, whether those of sacrifice or Olympian victors or others. Add to this the relief is capable of the greatest variety of form. It not only fills up and decorates the friezes and walls of temples, but is attached to utensils of all kinds, sacrificial bowls, votive gifts, shells, goblets, urns, lamps, and so forth; it is the adornment of seats and tripods, and is closely allied to the skilled crafts. Here as nowhere else the ingenuity of invention receives the fullest scope in every kind of form and combination, and is no longer in position to retain the true object of independent sculpture.
2. THE MATERIAL OF SCULPTURE
We have, by our acceptance of the principle of individuality, which is fundamental to sculpture, been compelled not merely to emphasize in separation the different provinces of the divine, human and natural, from which plastic art accepts its subject-matter, but also to classify the several modes of presentation in the single statue, group, or relief. In the same way we have to discover a like variety of division in the material which the artist can make use of in his works. For different kinds of content and mode of presentation are more particularly congenial to different kinds of sensuous material, and betray a secret attraction to and affinity with such.
By way of generalization I will merely here permit myself the remark that the ancients, in addition to the extraordinary excellence of their invention, equally excite our astonishment by reason of the amazing elaboration and versatility of their technical accomplishment. Both aspects present an equal difficulty in sculpture, because the means at hand here for such presentation are without the ideal many-sidedness, which is at the disposal of the other arts. Architecture is no doubt poorer still in this respect; but it is not her province to embody spirit in its vitality, or what is actually alive in Nature in a material which is by itself wholly inorganic. This elaborate dexterity in the absolutely consummate treatment of pure material is, however, bound up with the notion of the Ideal itself, for its very principle is a complete entrance into the sensuous concreteness and the blending together of the Ideal with its external mode of existence. The same principle is therefore once again asserted, where the Ideal attains its executed form and realization. In this respect we have no reason to wonder, when it is asserted that artists, in periods distinguished by great executive ability, either executed their works of marble in clay without models, or, if they had recourse to them, set about their work in a much freer and unconstrained manner than is the case in our own times, where, to put the fact bluntly, it only makes copies which are now executed in marble after originals carried out in the clay[188]. The old artists retained in fact the vital enthusiasm, which is always to a more or less extent lost in the case of copies and replicas, although it is undeniable that now and again we meet with defective work in famous masterpieces, as, for example, eyes that are not of the same size, ears one of which is placed lower than the other, feet that are of unequal length and others of the same kind. They did not lay so much stress on the absolute precision of the compass in such things as ordinary production and art criticism, that mediocrity of talent which imagines itself so profound, is wont to do; and it can do little else.
