ration of the Tuscanorder, considered by architects as a spurious orplain sort of Doric, and hardly entitled to remarkas a distinct order. E in the frieze correspond-ing to the triglyph, illustrates still further theconnection of the two orders; but by manyarchitects this member is not introduced. No. iis an elevation of capital and entablature, No. 2of the base, and No. 3 of a detached capital.Our example is constructed according to therules given by Vincent Scamozzi. Examples of two capitals are given, differingmerely in the number of mouldings in the abacus. In fact, this introduction of simple mouldingsis about the only variety allowable in the order.Ornament is not admitted, nor are the pillarsever fluted. A slightly convex curvature, or entasis, isgiven in execution to the outline of the shaft ofa column, by classic architects, just sufficient tocounteract and correct its appearance, or fanciedappearance, of curvature in a contrary direction 228 ARCHITECTURAL DRAWING SELF TAUGHT

No. 4 represents the form of a half columnfrom the Pantheon at Rome. In No. 5 anotherexample of entasis, the lower third of the shaftis uniformly cylindrical; the two upper thirdsare divided into seven equal parts. On thesemicircle shown in the figure, is a chord cut offparallel to the diameter, the length of which isfifty-two parts only one-half being shown.Divide the part a b of the circumferencebetween the diameter and chord into sevenequal parts, and draw parallel lines from eachdivision to those of the upper part of thecolumn, which will give the diameter of theshaft at each division; by increasing the numberof the divisions, more diameters for differentparts of the shaft may be found. Fig. 240 exhibits an example of the Doricorder, from the temple of Minerva in the islandof Egina. The dimensions are given in parts oft
