So also the objects of useful art will resemble in form precisely as they resemble in purpose; and where the purpose is similar, and the deviation which is admissible is slight, this becomes a subject of great nicety, and, if ornament be at the same time admissible, a subject of exquisite taste. It was by the transcendent exercise of these qualities, that the Greeks succeeded in fixing the orders of architecture. The most beautiful columns would have shocked the sight, if their mass had not corresponded to that of the edifice which they sustained; and the difference which existed in this respect, required a difference of ornament. Home indeed observes, that "writers on architecture insist much upon the proportions of a column, and assign different proportions to the Doric, Ionic, and Corinthian; but no architect will maintain, that the most accurate proportions contribute more to use, than several that are less accurate and less agreeable." That such a man should have committed such an error is surprising. It seems evident that the different proportion in the columns of these orders is admirably suited to the different quantity of matter in their entablatures. A greater superincumbent mass, required shorter and thicker columns; a less superincumbent mass, longer and slender ones. Many experiments, much observation, were requisite to determine this; but the Greeks had the means of making them, and solved every problem on the subject; and the result of the perfection they attained is, that all err who depart from the truth they have determined. It was, again, the differing quantities of matter in the entablatures, and the accurately-corresponding dimensions of the columns that determined, of course amid infinite experiment and observation, the nature of their ornaments. Hence, the Doric is distinguished by simplicity; the Ionic by elegance; and the Corinthian by lightness, in ornament as well as in proportion. Even, therefore, if we were to destroy all the associations of elegance, of magnificence, of costliness, and, still more than all, of antiquity, which are so strongly connected with such forms, the pleasure which their proportions would afford, would remain, as in all cases where means are best adapted to their end. In his objections to proportion as an element of beauty, Burke only confounds this kind of beauty with that which I have next to describe.
