One mode of columniation and intercolumniation which remains to be spoken of, is that which has sometimes been practised by Modern Architects, and combines the two extremes of pycnostyle, or still closer intercolumniation, and aræostyle. This consists in coupling the columns and making a wide intercolumn between every pair of columns, so that as regards the average proportion between solids and voids, that disposition does not differ from what it would be were the columns placed singly. Although denounced by some critics, more especially Algarotti, as altogether licentious and indefensible, and although it is not to be especially recommended, or indeed practicable on every occasion, the coupling of columns may, under some circumstances, be not only excusable, but advisable and proper. As is the case with almost every thing else in matters of art, all depends upon _how_ it is done, and whether with or without sufficient reason. That there is no classical authority for it, is no valid reason against it; in the constitution of the ancient temples there was nothing to require or _motive_ it. It may be conceded, however, that coupled columns, forming a prostyle surmounted by a pediment, are objectionable; because where so strong a resemblance to the antique model is preserved in other respects, a departure from it in regard to the disposition of the columns has a disagreeably disturbing effect. Having gone through the Classical Orders, and explained their elements and constitution, we have performed as much as we purposed, or as we promised. Within the same compass we might, no doubt, have touched upon a great deal besides that belongs to the study of Greek and Roman Architecture, by restricting ourselves to bare matter-of-fact, and suppressing all comment, and so treating the subject drily and superficially. Proceeding upon the principle of _multum haud multa_, we have aimed at nothing more than to initiate the reader in such manner as to excite interest in the subject, and stimulate to further inquiry. Should we have effected that, and should we have disabused him of the prejudices and contracted notions generally entertained in regard to the Orders, or else armed him against them, we shall have accomplished the _multum_—the main point of all. _Much_ shall we have taught, and much will he have learnt, should he now reject the fatal doctrine of the Five Orders, and relinquish it to school-boys and school-masters,—to the plodders who work by pattern, and design by rote and by routine. Much, very much indeed, will have been learnt, by the reader, should he have learnt or have been put in the way of learning, to look upon those various compositions in the three several styles of columniation, which are called Orders, not with the eyes of a Builder or a Mechanic, but with the intuition and the feeling of an Artist; in short, to look upon them as general _types_ to be diligently studied, and then imitated with congenial gusto.
