One Corinthian Modillion comes over the axis of the corner column and one over the outer face of the Double Dentil, Fig. 94. In drawing the side of a Modillion, put in first, at the outer end, a semicircle half its height and one at the inner end nearly the whole height; then the rosettes, one twice as large as the other; then the connecting curves, and finally the leaf beneath, Fig. 101.
In Palladio's Composite Cornice, one block is set over the axis of the column, and the double block at the corner has its inner face on a line with the face of the Frieze below. The blocks are about half a Diameter, on centers, the inter-block being one twenty-fourth of a Diameter wider than the block itself, Fig. 102.
Architraves.—The Tuscan Architrave, Fig. 103, has but one fascia or band, the Composite two, Fig. 107, and the Corinthian three, Fig. 106. The Doric 'has sometimes one, but generally two, Fig. 104, and the Ionic has generally two, Fig. 105, but sometimes three. The lower band is always the narrowest and is set on a line with the face of the Shaft below and of the Frieze above.
All the Architraves have a Cymatium, or crowning member, which in the Tuscan and Doric is a broad Fillet, called the Tsenia, and in the Ionic and Corinthian is a large Cyma Reversa, surmounted by a Fillet and generally supported by a bead. The lower bands often have, as a Cymatium, a small Cyma Reversa, Bead, or Ovolo, and all three bands are sometimes sloped backwards, as in the Entablature of the porch of the Pantheon in Rome, Fig. 108, so as to diminish the projection of the crowning moldings, which otherwise have a projection, beyond the face of the Frieze, equal to their height.
The Tuscan Taenia has beneath it the characteristic Tuscan congé, Fig. 103. Beneath the Doric Tænia, and directly under each Triglyph, Fig. 104, is a narrow Fillet, which sometimes has a beveled face, called the Regula, beneath which are the six Guttae. These are sometimes frusta of cones, as in the Greek Order, sometimes of pyramids. The Guttæ, which almost touch at the bottom, are twice as high as the Regula. Both together are just as high as the Tænia, or one-twelfth of a Diameter, so that the three are one-sixth of a Diameter high. They accordingly occupy the upper third of the height of the Architrave, which is three-sixths high, the lower band occupying the lower third.
The two lower bands of the Corinthian Architrave occupy half its height, and the lower band with its Cymatium is just as wide as the moldings that crown the upper band. The second band with its Cymatium is just as wide as the third band without its Cymatium, Fig. 106.
Capitals and Bases.—In drawing Capitals, it is best to put in first the axis of the column and the vertical faces of the Shaft; then the horizontal lines, and lastly the profile, beginning at the top. But in drawing Bases, it is best to put in the profile of the molding before the horizontal lines.
