The metopes were originally open interstices between the beams; intertrabies, as they might be called, with reference to the intercolumniations; having, upon the peripteros, been closed within and without by light slabs, the votive offerings, formerly placed in the apertures, were now superseded by sculptures in relief upon these stones, which gave to the entire entablature—or, when the carving was restricted, to that of the fronts—an imposing decoration. A continuous band, like that beneath the triglyphs, terminated the frieze; but the individuality of triglyph and metope was even here maintained, the superposed member being broken around them, as a separate coronation for each.
The cornice showed reminiscences of the projecting eaves by its corona being cut with a downward slant, such as would never have been invented for the treatment of stone. That this inclination was not precisely the same as the pitch of the roof rafters cannot be adduced as an argument against its fundamental idea; in the marble structure there was nothing to call for so exact a resemblance. The decoration of the lower surface of the corona shows the original motive of its wooden construction as distinctly expressed as was the formation of the triglyph in the frieze. The position of the ends of the rafters, beneath the sheathing, is marked by boards, each being pinned upon it with eighteen wooden pegs. From the duplication of the triglyphs in the stone building there resulted an equal number of mutules, and these were still further multiplied by being placed over each metope—this latter increase having been at first attempted with members of half the normal width, as at Fig. 136. The whole composition was thus the more richly divided the higher the building ascended; upon one column rested two triglyphs and four mutules. It is further remarkable that, to make the decoration harmonious upon all sides of the edifice, these mutules were also introduced upon the front and rear entablatures; this repetition, with the inclination of the corona upon the fronts, naturally without a gutter, must be regarded as a further concession, made, contrary to the genetic signification of members, in favor of the monumental appearance of the entire exterior. The corona is bordered by the so-called Doric cyma, or beak-moulding, distantly resembling the scotia of Egypt and Mesopotamia. The concluding gutter is of a beautifully curved outline. When it occurs upon the sides of the building, where it is frequently restricted to the corners, it is provided with lions’ heads, which, arranged over the columns as gargoyles, throw from their open jaws the rain-water of the roof beyond the steps of the crepidoma. An isolated instance—the Heraion of Olympia, which seems never to have been provided with a stone entablature—shows that the timbered roof and ceiling were placed at times with a wooden epistyle directly upon the stone columns of a peripteros. The covering of the roof was formed, in the best period, by flat marble tiles, the joints of which were covered by smaller curved blocks, running from ridge to eaves, and terminated over the cornice by antefixes. The apex and corners of the gable were provided with acroteria, standing upon special bases. They are reminiscences of an ancient usage of Western Asia: those of the corners found their origin in the ornaments of primitive altars and sarcophagi, known in Biblical accounts as horns. They were sometimes supplanted by votive offerings suited to the position, such as tripods, or by griffins and other symbolical figures. The pointed acroterium of the apex was usually the whole of the two half-anthemions represented upon those of the corners; in larger monuments it was often replaced by statues, just as extended compositions of figures were created for the tympanon beneath, as a substitute for the dedicated objects which appear to have originally filled the gable.
The polychromy of the Doric temple was one of the most important features of its external appearance. It is probable that the greater part of its marble surface, possibly the whole, was colored. Our Northern conceptions can with difficulty comprehend the full value of this treatment in the general composition; in our gray landscape, a building thus painted might appear harsh and variegated. The color of the lower supporting members was restricted to a light tint, the so-called baphe, which had first been applied to the stucco priming necessary for the coarse and porous stone of older temples, and was afterwards transferred from this to the marble of later monuments. It stained the surface with a light golden-brown tint, moderating the harsh chalky white of lime stucco, or of marble, and investing the newly erected building with the patina by which age always modulates the color of stone. This baphe was employed for the marble temple on account of the traditional painting of the stucco priming, because of the too dazzling white natural to the freshly hewn material, and, finally, in order to harmonize the columns and stylobate with the intensely rich colors of the entablature. Dark and positive pigments were restricted to the frieze and cornice, having, without doubt, been first employed to preserve the original wooden material. The beams and slat-work, like the triglyphs with their regulas and the mutules, were designated by blue; the trunnels were red or gilded. That which had at first been open was treated as a dark-red background; the metopes and tympanon thus clearly outlining the reliefs and groups of statues which ornamented them. The continuous members were treated with particular richness; the narrower strips were painted with the meander and other woven forms; the gutter with anthemions; while the Doric cyma was decorated with leaves of various colors, so artistically conventionalized as but little to resemble nature. The inner side of the entablature was still more richly colored. (Fig. 140.)
