The cornice is noticeable for the projecting blocks which depend from the corona and which are called mutules (Fig. 8). This cornice (Plate V) has the same height as the preceding one (Plate IV), but it differs in its projection, which is forty-two. The height is divided in the following manner: the band above the triglyph four, the fillet 1.5, the quarter round three and five-tenths, mutules six and five-tenths, cyma-reversa one and five-tenths, the corona eight, cyma-reversa one and eight-tenths, fillet one and two tenths, cyma-recta six, and the listel three. The projection is divided as follows: the thickness of the triglyph two, band and listel one, quarter-round three and five-tenths, the, fascia five tenths, mutules twenty-four and five-tenths, corona two and five-tenths, fillet projection with cyma reverse two, and the cyma-recta six.
The mutules have a face five and five-tenths in height and form a profile composed of a square of one, a drip of one and five tenths, and a reglet of two. The lower face of the mutules in Plate V is decorated with five rows of guttae, six in a row. As the mutules correspond in their position and in their width to the triglyphs, so the divisions of the guttae correspond with the edges of the channels of the triglyphs.
60. ' In the Doric Order the axes of columns and pilasters always correspond to the axes of the triglyphs above them. The upper semi-diameter of the column being twenty-two, the axis of the first triglyph is placed at twenty-two from the angle. The triglyphs are twenty-four in width, and the spaces which separate them are thirty-six. These spaces are exactly square, having a width equal to the height of the frieze, and are called "metopes." The mutules are of the same width as the triglyphs, twenty-four, and are placed on the same axes. Sometimes the metopes are decorated with objects of sculpture whose character is suggested by the character of the edifice. (Plates VIII and IX.) 61. The under part of the corona, or "soffit" of the Doric cornice is divided like the frieze, its divisions corresponding to the triglyphs and the metopes, as we have already seen. The arrange ment of the soffit at the angle must be carefully observed:— in the lenticular cornice, Fig. 9, there is included in the corner a division which corresponds to the width of the metope: first, a division of five; second, a division of 13; third, another division of five; and finally—at the angle—a square of twelve and a fillet of one. These parts are decorated with panels where sometimes are placed rosettes, winged thunder bolts, or other ornaments in accor dance with the character of the edifice. In the soffit of the mutular
cornice (Plate IX) there is at the angle a square of twenty-three and five-tenths, decorated with a panel which may be filled with sculpture, such as the winged thunder-bolt. The space between this panel and the mutule is ornamented with lozenge shaped panel, in which is a rosette.
62. The cymatium or cap of the pedestal (Plate VI) is four teen parts high, of which the divisions are: a fillet of one, quarter round of three, corona of seven, and listel of three. Its projection is nine, of which four is the projection of the congo and quarter round, three and five-tenths of the corona, and one and five-tenths of the listel.
The base of the pedestal is forty-five in height, divided among a first plinth twenty-five, second plinth ten, listel three, cyma reversa five, and fillet two. The projection of the base is eight, of which one is for the first plinth, one for the second plinth, four for the cyma-reversa, and two for the conge. The die of the pedestal is eighty-one parts high and its sides are in plane with the faces of the plinth of the column base.
63. The impost is twenty-five in height; it is composed of an astragal of three, a necking of seven, a fillet of one, a quarter round of three, a corona of eight, and a listel of three.
The projection of the impost is eight; for the quarter-round and fillet four, for the corona two and five-tenths, and for the listcl one and five-tenths. The astragal projects two.. The archivolt is thirty in height; it is composed of a first band nine, second band eleven and five-tenths, fillet one and five-tenths, quar ter-round four, and listel four.
The projection of the archivolt is six; second band one, fillet one, quarter round three and five-tenths, and listel five-tenths.
64. The width of the Doric pilaster in proportion to the column is shown in Fig. 10. The lower diameter of the Doric column being fifty and its upper diameter forty-four, the difference is six, which is divided into three equal parts, of which one is taken for the differ ence in width between the neck and base of the pilaster, forty-eight being the width at the base and forty-six at the bottom of the cap.
The difference of pro jection of the bases is made up in the cong6 which pro jects two for the column and three for the pilaster.
The difference in the pro jection of the caps is made up in the three annulets and the quarter-round of the denticular capital and in the astragal and quarter round of the mutular capi tal.
