In the same way we must discount that which is admitted by art in deference to traditional religion. We have already found it to be true in the classical type of art that it does not forthwith and immediately set forth the Ideal, in which its function is to discover its fundamental lines of definition, but in the first instance removes much that is inconsonant with it and foreign; it is the same case precisely with sculpture. It is forced to pass through many preliminary stages before it arrives at its perfection; and this initial process differs very considerably from its supreme attainment. The most ancient works of sculpture are of painted wood, as, for example, Egyptian idols; we find similar productions among the Greeks. We must, however, exclude such examples from genuine sculpture when the main point is to establish its fundamental notion. We are therefore in no way concerned to deny that there are many examples at hand of painted statues. It is, however, also a fact that the purer art-taste became, the more strongly "sculpture withdrew itself from a brilliancy of colour that was not really congenial, and with wise deliberation utilized, on the contrary, light and shadow in order to secure for the beholder's eye a greater softness, repose, clarity, and agreeableness[130]." As against the uniform colour of the bare marble we may no doubt not merely instance the numerous statues of bronze, but also in still stronger opposition the greatest and most excellent works, which, as in the case of the Zeus of Pheidias, were artificially coloured. But we are not here discussing absence of colour in such an extreme abstract sense. Moreover, ivory and gold are not primarily the use of colour as the painter employs it; and generally we may add that the various works of a definite art do not ever in fact retain fixedly their fundamental notion in so abstract and unyielding a way, inasmuch as they come into contact with the conditions of life subject to aims of all kinds; they are placed in different environments, and are thereby associated with circumstances of an external kind, which inevitably modify their real and essential type. In this way the images of sculpture are not unfrequently executed in rich material such as gold and ivory. They are placed on magnificent chairs or stand on pedestals which display all the extravagance and luxuriousness of art, or receive costly decorations, in order that the nation, when face to face with such splendid works, may likewise enjoy the sense of its power and wealth. And sculpture in particular, for the reason that it is essentially, taken by itself, a more abstract art, does not on all occasions hold fast to such exclusiveness, but, on the one hand, introduces incidentally much that is of a traditional, scholastic, or local character as a contribution from its history, while, on the other, it ministers to vital popular necessities. Active humanity demands for its diversion variety, and seeks in diverse directions for a stimulus to its vision and imagination. We may take as an analogous case the reading aloud of Greek tragedies, which also brings before us the work of art under its more abstract form. In the wider field of external existence we have still to add, to make a public performance, living actors, costume, stage scenery, dancing, and music. And in like manner, too, the sculptured figure is unable to dispense with much that is supplementary on its own stage of reality. We are, however, only concerned here with the genuine work of sculpture as such; external aspects such as those above adverted to must not be permitted to prevent us bringing before the mind the notion of our subject-matter in its most ideal and exclusive sense of definition.
