The total projection of the base is eight; in this is included the conga of the column whose projection is one and five-tenths.
97. The cap of the pedestal is twenty parts in height divided among an astragal of two, a small frieze of five and five-tenths, second astragal of two, a cyma-recta of two and five-tenths, corona of five, a cyma-reversa of one and seven-tenths, and a fillet of one and three-tenths. The total projection of the cap from the die of the pedestal is eight.
The base of the pedestal is forty parts in .height; it is com posed of a first plinth of twenty-four, a second plinth of six, a torus of three and five-tentbs, a reversed cyma-recta of three and five-tenths, with a fillet of one, a bead one and five-tenths, with a fillet of five-tenths. The total projection is seven and five-tenths, of which one is for the first plinth.
98. The impost is twenty parts in height and is composed of an astragal of two; frieze, five and five-tenths; fillet, five-tenths; bead, one; quarter-round, two and five-tenths; corona, five; cyma reversa, two; and listel, one and five-tenths.
The total projection of the impost is seven, but for the arches between which a column with a pedestal is used, there is a greater projection of the corona of the impost. In this case the impost projection is eight.
100. The channels of the Corinthian column are twenty-four in number. The width of the fillet which separates them is one third of the channel width. The width of a pier of the arcade is equal to the width of a column plus two archivolts which is eighty four parts.
101. The Corinthian pilaster and column relation is shown in Fig. 15: the pilaster width at the base is thirty-nine; at the height of the capital it is thirty-seven. The width of the pilaster differs from the diameter of the column, being one part less at the base and one more at the height of the capital. The base of the pilaster projects eight and five tenths so that the total, width may be equal to that at the base of the column. The width of the abacus of the pilaster capital is equal to that of the capital of the column.
102. When the pilaster is chan neled, there is formed at each angle a bead of one part and the remaining width is divided into twenty-nine equal spaces which in turn are divided into seven channels of three spaces, and eight fillets of one space each. The summits and the bases of the channels correspond to the starting point of the conges.
This rule for fluting of columns and pilasters is also applicable to the Ionic Order.
103. The drawing of the keystone console of the Corinthian arch as shown in Fig. 16 is a little different from that of the Ionic Order, but is drawn in accordance with the same rules.
