accidental limitation; for sometimes, for example, it is only under the guidance of symmetry that one knows whether one has before one three buildings standing beside each other or only one. Thus only by means of symmetry does a work of architecture at once announce itself as individual unity, and as the development of a central thought.
Now although, as was cursorily shown above, architecture has by no means to imitate the forms of nature, such as the stems of trees or even the human figure, yet it ought to work in the spirit of nature, for it makes the law its own, natura nihil agit frustra, nihilque supervacaneum, et quod commodissimum in omnibus suis operationibus sequitur, and accordingly avoids everything which is even only apparently aimless, and always attains the end in view in each case, whether this is purely architectonic, i.e., structural, or an end connected with usefulness, by the shortest and most natural path, and thus openly exhibits the end through the work itself. Thus it attains a certain grace, analogous to that which in living creatures consists in the ease and suitableness of every movement and position to its end. Accordingly we see in the good antique style of architecture every part, whether pillar, column, arch, entablature, or door, window, stair, or balcony, attain its end in the directest and simplest manner, at the same time displaying it openly and naively; just as organised nature also does in its works. The tasteless style of architecture, on the contrary, seeks in everything useless roundabout ways, and delights in caprices, thereby hits upon aimlessly broken and irregular entablatures, grouped columns, fragmentary cornices on door arches and gables, meaning less volutes, scrolls, and such like. It plays with the means of the art without understanding its aims, as children play with the tools of grown-up people. This was given above as the character of the bungler. Of this kind is every interruption of a straight line, every altera-
