7hc Grecian Orders

ceeded them, did not imagine that it would want any additional projeeture for the sake of greater
Solidity r that the simplicity of its character could not admit of a base ? sor as the statue of z
Hercules, or of a wrestler would appear out of character if their feet were dressed up in (c) san-
dais or shoes, so would the column to which they had annexed these ideas.
The number of slutings (V) to the Doric column should never be more or less than twenty.
Sometimes it was left with the sides flat and XX angles. The curvature of each ssuting is de-
scribed from the center of a geometrical square, X whose sides are equal to one of the flat sides.
Others have traced the curvature from the summit of an equilateral triangle Z. whose base is
one of the ssat sides. The entablature and capital may be traced by scales of equal parts, e.g.
For the capital divide its entire height into two equal parts; take the uppermost for the abacus.
Again divide c. d. into three equal parts; two of these are for the ovolo, and the remaining one
is divided into three for the fillets: sor the fourth fillet belongs to the maft of the column; the
presecture of the abacus is three parts of its height j that of the ovolo is equal to its own height,
and the fillets are profiled, as is seen by the figure.
For the entablature, divide the height into seven equal parts, and each of these again into three j
take seven of these subdivisions for the height of the architrave, and eight of the same for the
height of the frize, the six-remaining will stand for the height of the cornice, which being di-
vided into twelve, will asfign to each member its relative number of parts, as may be seen by the
figure
The cornice projects once and a half of its height, then divide this proiedture into nine equal
parts, and the profiles are determined and described, as the figure readily Iheweth; but the mo-
dulary scale is added, and the disferent measures os the members may be taken by it.
The capital C consists os a plain abacus, an ovolo under it, with (e) three annulets, for the
fourth belongs to the shaft or full of the column. With very little alteration, the text in Vi-
truvius agrees with this division.
The entablature described between C. and A. by beginning at bottom, consists I. Of the Ar-
chitrave of only one fascia, with the Tamia, fillet, and six drops. These drops are disferent
from those hitherto used: the simplicity and height of the architrave gives it a superior degree
of strength to all others, commonly described.
II. The frize, considing of the (/) triglyphs and (g) metopes j the height of the triglyph is
one module and four parts, and its breadth one module. The breadth of the metope between
