It should be noted that throughout this Order the abacus is square in plan, and is ornamented around its upper edge with a cyma reversa and fillet. From the bottom of the abacus, the column and mouldings are round or circular in plan down through the torus of the base. This torus rests upon a plinth square in plan and rectangular in section. The soffit of the cornice, shown in this plate, is drawn out in Fig. 116. In Plate VIII, Part I, is shown another Roman Doric Order, after Palladio, in which there are no mutules in the cornice and the dentils are also omitted. This plate should be compared with the two pre ceding plates in order to understand the great possible variation in the mouldings, sections, etc. It should be mentioned that a fault in the Order in Plate IX, Part I, is the slight projection of the triglyph, mak ing necessary so flat a treatment of the half-channel occurring on its two edges that in practice it would be barely perceptible. This tri glyph would much better have a section of as much projection as is shown in Fig. 114.
Other Forms of Doric. The Doric Order from the Villa at Albani near Rome, is shown in Fig. 117. It is an interesting but some what peculiar instance of the use of the Doric Order, especially in the treatment of the guttæ on the mutule soffit, as well as in the triglyph and architrave treatment below. The Roman Order from the Baths of Diocletian at Rome, shown in Fig. 118, is of rather a late date (about A. D. 290), as is further borne out by the charac ter of the mouldings and their over-ornamentation—all quite typical of later Roman archi tecture.
Neither this example nor the one shown in Fig. 117 is to be advocated for exact reproduction in general work, although both of them contain many valuable sug gestions f o r, t h e treatment of various parts of the Roman Doric Order.
The capital from Pompeii, illustrated in Fig. 119, is an interesting variation on the Greek form, that is typical of much of the early Roman work. The column shafts of this period were all tall and slender in their proportions.
