(a) The vitality of these works consists in this, that they are the free product of the genius of the artist. The artist at this stage is neither satisfied with giving, by means of general and haphazard contours, suggestions and expressions, a general conception of that which he desires to reproduce, nor does he, on the other hand, in respect to what is individual and singular, accept the forms as he has received them by chance from the external world. For this reason also he does not present them again with loyalty to this accidental aspect, but he is concerned to place within his own free creation what is empirically particularized in isolated aspects that thus appear in a further individual accord with the universal types of the human form, an accord which is made to appear as throughout transpierced with the spiritual configuration of that which he is called to make apparent, when he suffers us to see his own vitality, conception and animation in the work regarded on the side of the artist's activity. The universal aspect of the content of his work is not due to his creation. It is presented him by means of mythology and saga precisely in the way that he finds the general effect and details of the human form; but the free and living individualization, which permeates all portions on his work, is the result of his own personal point of view, his efforts and services.
(b) The effect and charm of this vitality and freedom is only produced by means of the sufficiency, the honest candour of the elaboration of all the particular parts to which the most definite knowledge and review of the construction of these parts belongs, no less in their position of repose than also in that of their motion. The way in which the different members are disposed and moulded with regard to rondure and smoothness, in every condition of rest and movement, must be expressed in the most satisfactory way. This fundamental elaboration and placing in relief of all the separate parts we find in all products of antique art, and the animation thus produced is only the effect of infinite pains and truth. When the eye contemplates works of this kind it is, in the first instance, unable clearly to recognize a mass of distinction; and it is only by virtue of a particular manner of lighting that we can appreciate the same by means of a stronger contrast between light and shadow. But though these fine nuances are imperceptible at first glance, the general impression they produce is not for that reason lost. In part they appear as the spectator varies his point of view, and in part we derive from them what is essentially the impression of the organic continuity of all the members and their forms. This spirit of vitality, this soul of material configuration, is due wholly to the fact that, though every part is entirely complete in its separable independence, yet it is to a like extent throughout, by virtue of the wealth of its modes of transition, associated not merely with the part that is immediately its neighbour, but with the entire work. For this reason the form is vital in every part of it; the least detail of it is stamped with purpose; every part of it is differentiated from the rest, possesses that which distinguishes it and makes it distinct, and yet is affected by the same fluidity of treatment, is only what it is vitally as a part of the whole, so that we are able to recognize the whole in the very fragments of it, and a part that is broken off enables us not merely to see but to enjoy a totality that is not thus mutilated. The material surface, although for the most part statues are now seriously impaired by the weather and other causes in this respect, presents a soft and malleable appearance; and in one particular example of the head of a horse I have in mind it literally glows with the ardour of life on the face of the marble itself. This scarce perceptible undercurrent of fluidity in all organic parts, united to the most conscientious elaboration which avoids purely regular surfaces and anything approaching the bare convexity of circular shape, supplies that softness and ideality of all parts, that harmonious unity, which extends throughout the whole as the spiritual breath of one animating presence.
(c) However true, notwithstanding, expression of detailed or general configuration may be, this truth is no mere imitation of Nature simply. Sculpture is always occupied with the abstraction of form, and is consequently obliged, on the one hand, to omit from the bodily presentment what is most essentially the natural aspect, in other words, what is exclusively indicative of natural function. From a further point of view it is unable to carry to extremes its particularization of detail, but rather as, for example, in its treatment of hair, must restrict its attention and reproduction to the more general of its forms. In this way, apart from any other, the human figure, when properly treated by sculpture, is at once declared as the form and expression of Spirit, rather than of a purely natural form. Closely connected with this consideration is the fact that, though a spiritual content is expressed by means of sculpture in the bodily form, yet in the genuine Ideal it is not asserted so prominently in the exterior form to the extent of making that which is simply external in its charm and grace either the exclusive or predominant attraction to the spectator. On the contrary, though the genuine and more severe Ideal of Spirituality is here presented in bodily shape, and is exclusively thus presented by means of such shape and its expression, yet this configuration must equally appear to be without exception unified, supported and transfused by this ideal content. The swell of life, the malleability and bodily presence, or sensuous fulness and beauty of the bodily organism, must as little supply independently the object of the presentation, as what is individual in the spiritual presence can be carried to the length of expressing the more intimate and more closely related inner life of the spectator, when we consider his own particularity.
2. THE PARTICULAR ASPECTS OF THE IDEAL FORM OF SCULPTURE AS SUCH
If we direct our attention now to the more specific consideration of the fundamental phases, on which the ideal form of sculpture reposes, we shall do well to follow Winckelmann in essentials, who has laid stress on the several types with the finest intuitive sense, and with the most fortunate results, as well as on the way in which the same have been treated and shaped by Greek artists, with the result that they finally present to us the Ideal of sculpture. The vitality, this floating emanation no doubt evades the definitions of the understanding, which in the present case is unable to hold fast and transpierce the particular as in architecture, which, however, asserts itself in the entire work, as we have already seen, as the coalescence of free spirituality and bodily forms.
The first general feature of distinction which arrests us concerns the determination of works of sculpture in a general way, by virtue of which the human form has to express that which is spiritual. The spiritual expression, albeit it has to be poured forth over the entire bodily presence reaches its highest degree of concentration in the facial form, whereas the remaining members are merely able to reflect what is spiritual by means of their position, in so far, that is, as the same proceeds from Spirit in its essential freedom.
In our examination of these ideal forms we will make a beginning in the first place with the head; we will, then, in the second place enlarge upon the position of the body, after which we shall conclude with the principle of the drapery.
(a) In the ideal configuration of the human head we are first and foremost confronted with the so-called Greek profile.
(α) This profile consists in the peculiar union of the forehead and nose; in the almost straight or merely slightly crooked line in which the forehead unites without interruption with the nose, as also, to speak more accurately, in the vertical direction of this line to another which, extending it from the root of the nose to the orifice of the ear, forms a right angle with the line of the forehead and nose above mentioned. In a line of this sort nose and forehead stand throughout to one another in the ideal and fine art of sculpture, and the question presents itself whether this is a merely national and artistic contingency or a physiological necessity.
Camper, the famous Dutch physiologist, has, with more exactness and in an exceptional way, characterized this line as the line of facial beauty; he in fact discovers therein the main distinction between the form of the human visage and the profile of animal life; and on account of this follows up the modifications of this feature throughout the various human races. In this respect his researches are no doubt in conflict with those of Blumenbach[156]. Speaking generally, however, the line adverted to is in fact a most marked means of distinction between the outward form of man and animal. Among animals, it is true, muzzle and nasal bone also form a more or less straight line, but the specific projection of the animal's snout, which is forced to the front, as being in the nearest practical relation to objects, is essentially determined through its connection with the skull, united to which the ear is moreover placed above or below, so that in the present instance the line that is carried forward from the skull to the root of the nose or the upper jaw, where the teeth are in position, forms an acute angle instead of a right angle as is found in the case of man. Everybody can independently feel in a general way the strength of this distinction, which no doubt opens the path to more definite thinking on the subject.
