As the architrave expresses simple weight, and the frieze weight depending, so the cornice is weight impending. The great projection of this massive member beyond the face of the frieze and architrave contains in itself the ground of that expression; but it is carefully heightened by the deep undercutting of the corona, which throws the mass forward and separates it by a dark shadow from the top of the frieze; and it is still further heightened by a repetition of the rows of guttæ--which, however, in this instance seem to be sliding off the inclined faces of the mutules (inclined slabs set in the undercutting of the corona); so that the same device which gives dependent weight in the frieze, expresses weight impendent in the cornice. These are only a few of the more obvious means by which the lovely equilibrium of the Doric style is created. There are many other details which it is impossible to notice here; but every one bears the central thought constantly in view, and adds to the most perfect--though not perhaps the highest--architectural beauty which the world has ever seen. The other so-called “orders” are only modifications or corruptions of the same idea. III Before proceeding to show how the idea of Greek architecture, symbolised in a system of construction and decoration which emphasised to the eye in every detail an exact adequacy of endeavour to effect, was modified or corrupted in the so-called “Ionic,” “Corinthian,” and other “orders,” a few words should be said about the very peculiar and little understood treatment of the wall by the Doric architects. As a contrast to the active conflict of apparently ascending power in the columns with the gravitating power, rendered, as it were, visible in the entablature, the treatment of the walls of the _naos_, _pronaos_, and _posticum_--that is, of the body of the temple and of the porches created by the prolongation of the side walls--is emphatically passive and neutral, and just the reverse of the treatment of the wall by the Egyptians, who made it the base of a truncated pyramid, a mass of conscious ponderosity, which “lean’d down on earth with all its weight.” The vertical junctures of the stones of the walls of the Greek Temple were rendered invisible by polishing their adjacent faces; but the horizontal faces were rough-worked, so that the wall-face presented a series of straight lines parallel to the base. These lines were only strong enough to be plainly seen, through the gaps in that torrent of ascending power, the fluted colonnade; increasing that force by their contrast, but themselves expressing nothing but the fact that the wall was a wall, built in ordinary courses of masonry. Had the perpendicular junctures of the masonry been visible, the contrast to the shafts--which were either monoliths or had the junctures of the _frustra_ so polished that they looked like monoliths--would have been lost. The _antæ_, or ends of the
