If we wish to build a sublime Edifice, we ornament it to excess, creating pompous decoration that degenerates into confusion. If we wish to build a simple Edifice, we make a building that is merely uninteresting and devoid of dignity. [. . .]

The ornamentation that must be used only on the exterior of a house must not be used inside it. Each room must be arranged in the manner suitable to the master of the household, and given the size and decoration suitable for his use. [. . .]

The contours of the architectural mouldings and the other parts that compose a building are in Architecture like the words of discourse. All Edifices are formed by just three sorts of line – the straight line, the concave line and the convex line. These three lines also form the shapes of all architectural mouldings that make up the contours of a

building. New ones must be created only with great care and they should be used only in those places where they may be put.
