Thus, while falling under the law of conformity to an end, and ceasing to be independent, architecture escapes from the useful and submits to the law of the beautiful; or rather, the beautiful and useful meet and combine themselves in the happiest manner. Symmetry, eurythmy, organic forms the most graceful, the most rich, and the most varied, join themselves as ornaments to the architectural forms. The two points of view are united without being confounded, and form an harmonious whole; there will be, at the same time, a useful, convenient and beautiful architecture. What best marks the transition to Greek architecture, is the appearance of the column, which is its type. The column is a support. Therein is its useful and mechanical design; it fulfils that design in the most simple and perfect manner, because with it the power of support is reduced to its minimum of material means. From another side, in order to be adapted to its end and to beauty, it must give up its natural and primitive form. The beautiful column comes from a form borrowed from nature; but carved, shaped, it takes a regular and geometric configuration. In Egypt, human figures serve as columns; here they are replaced by caryatides. But the natural, primitive form is the tree, the trunk, the flexible stock, which bears its crown. Such, too, appears the Egyptian column; columns are seen rising from the vegetable kingdom in the stalks of the lotus and other trees; the base resembles an onion. The leaf shoots from the root, like that of a reed, and the capital presents the appearance of a flower. The mathematical and regular form is absent. In the Greek column, on the contrary, all is fashioned according to the mathematical laws of regularity and proportion. The beautiful column springs from a form borrowed from nature, but fashioned according to the artistic sense. Thus the characteristic of classic architecture, as of architecture in general, is the union of beauty and utility. Its beauty consists in its regularity, and although it serves a foreign end, it constitutes a whole perfect in itself; it permits its essential aim to look forth in all its parts, and through the harmony of its relations, it transforms the useful into the beautiful. The character of classic architecture being subordination to an end, it is that end which, without detriment to beauty, gives to the entire edifice its proper signification, and which becomes thus the principal regulator of all its parts; as it impresses itself on the whole, and determines its fundamental form. The first thing as to a work of this sort, then, is to know what is its purpose, its design. The general purpose of a Grecian temple is to hold the statue of a god. But in its exterior, the character of the temple relates to a different end, and its spirit is the life of the Greek people.
