(_γγ_) From this it is clear that though no doubt walls may serve as support, yet, for the reason that the function of support is already independently performed by columns, they must, on their part in finished classical architecture be accepted as essentially having for their object the enclosure. If they are taken as columns are taken, to provide means of support, the essentially distinct defining functions of these latter are not, as is most desirable, performed also as by distinct constituent parts of the building[90], and the conception of what walls ought to provide is impaired and confused. We consequently find even in temples that the central hall, where the statue of the god was placed, to enclose which was the main object, is often left open in the upper part. If, however, a roofing is required, the claims of the lofty style of beauty made it necessary that the same should be supported independently. In other words the direct imposition of entablature and roof on the enclosing walls is purely a matter of necessity and need; it is not appertinent to free architectural beauty, because in the art of classical buildings we require as means of support neither partitions nor walls, which would be rather derogatory to the design in so far as--we have already noticed the fact--they put together contrivances and a wall-space of greater extent than is actually necessary. These would be the main distinguishing features which in classical architecture we have to keep apart. (_c_) Although we may then, on the one hand, declare it as a principle of first importance that the distinctions which have been summarily indicated must appear with their _differences_ emphasized, it is equally necessary on the other that they should be _united in a whole._ We will shortly, in conclusion, draw attention to this union which in architecture will be rather and simply a juxtaposition, association, and a thorough eurhythmy of the entire construction. Generally speaking the Greek temple buildings present an aspect which both satisfies, and if we may use the expression, sates us to the full. (_α_) There is no soaring up, but the whole just expands on the broad level and is extended without particular elevation. In order to view the building's face it is barely necessary to raise the sight with intention; it is, on the contrary, allured to the bare expanse, while the building art of Germany in the Middle Ages strives up almost without mass and soars. Among the ancients breadth, regarded as secure and convenient foundation on the earth, is the main thing. Height is rather borrowed from the height of man, and merely is increased in proportion as the building increases in breadth and width.
