Sometimes, in order to give increased richness to the capital, certain mouldings are carved. The'cyma-reversa of the abacus is adorned with the leaf and tongue ornament, the quarter-round with eggs and darts, and the "baguette" or bead with beads and reels.
54. The Doric base is twenty-four parts in height, divided among the plinth of twelve, the torus of nine, and a bead or ring of three; the fillet below the conge of the column is two in height. The projection of the base is eight, comprising the conge of the column,which is two, the bead 1.5, and the torus 4.5.
55. The Doric entablatures are shown in Plates IV and V. The architraves hgve a characteristic ornament which consists of a row of small truncated cones (or pyramids) called "guttae," attached below the listel of the architrave to a small band called the reglet or taenia. Their position corresponds to the channeled parts of the frieze above, which are called the triglyphs. Notice that the denticular architrave is composed of a single band crowned by a listel, while the mutular has two bands, of which the upper projects beyond the one that rests upon the capital. These bands are designated by the name fascia or "facure." Both styles of Doric architraves are twenty-seven parts in height, of which four are given to the listel.
The lower band of the mutular Doric architrave is nine parts in height; the height of the guttae is three, of the reglet or "taenia" one. The denticular style has but one projection, that of the listel, which is three. The mutular has a projection of four, because of the added projection of the second fascia which is one. The guttae are spaced four parts from center to center; their lower 'Width is three and the upper width two. The face of the taenia is parallel to the slope of the guttae. The projection of the guttae from the face of the architrave is 2.5 on the bottom, and two at the top.
56. The frieze of the Doric Order is thirty-six parts in height and is distinguished by its triglyphs, which are apparently the extremities of beams, forming on the frieze a slight projection of two parts, and spaced at regular intervals.. The name comes from the triangular channels with which they are ornamented.
The detail of this ornament as well as of the dependant guttae is clearly shown in Fig. 7.
57. The cornice of the denticular Doric Order is thirty-seven parts in height and its projection is forty. It is composed first, of a band four parts in height and one in projection, forming a slight projection of .5 over each triglyph; second, a cyma-reversa of three in height and 2.5 in projection, placed with a projection of five tenths over the head of the triglyph; third, a band six in height and five-tenths in projection over the cyma-reversa; against this band are placed small blocks, five parts in height and four in width, with a • space of two between them, which are called dentils; fourth, ;corona eleven parts in height comprising two fillets, of one part each which are seen in profile on the section AA and which, with the drip, are intended to carry off the rain water; fifth, a eyma reversa of 1.8 surmounted by a fillet of 1.2 and the whole project ing 2.2; sixth, a cavetto of six, and six in projection; seventh, a listel of four crowning the cavetto.
58. The two sections show that the dentils are surmounted under the corona by a cavetto of two in height, having a projection of two in which is included the offsetting projection of .5. This cavetto causes the soffit or lower face of the corona to be inclined two parts. This soffit is divided into panels of various forms corresponding to the- divisions of the frieze, as will be seen in Fig. 9. Those panels which correspond to the triglyphs are ornamented by round guttae, the position of which is de termined by the edges of the channels. The guttae are three parts in diameter at the lower face and two at their summit; they are one in height and are placed in three rows spaced four from center to center. The other panels are divided into lozenges and triangles and are sometimes ornamented with ro settes or other devices.
59. The frieze of the mutu lar order is distinguished only by a slight difference in the channels of the triglyph. The channels on the edges are eased off into a curve at the top, while the others form re-enter ing angles.
