1. That the objects be represented of such a size that the position of the spectator does not permit of his distinguishing either the coloured elements from each other, or the furrows which separate them; so that threads of two mixed scales (377), and the hatchings of different scales, more or less distant, interwoven together (378), may be mingled into a homogeneous colour, and that the cavities and salient parts may appear as a uniform surface. 2. That the colours be as vivid and strongly contrasted as possible, so that the lines which surround the different objects be more distinct, and the lights and shadows be as different as possible. 359. Thus patterns for tapestry must not only recommend themselves by correct outline and elegant forms, but must also represent larger objects: figures draped rather than nude, vestments decorated with ornaments, rather than simple and uniform. Consequently, every thing allied to miniature, by minuteness or by finish in details, is foreign to its special object. 360. The elements of Beauvais tapestry for furniture are essentially the same as those of Gobelins tapestry; but with this difference, that the light and the middle tones are of silk, while in the Gobelins tapestry these tones are almost always of wool. The scales of Beauvais are less varied in colour than those of the Gobelins, and their tones are less numerous. But the working of the threads is the same in both kinds of tapestry; so that as to the employment of coloured threads, depending in like manner on the knowledge and observance of the principles of mixture and contrast of colours, I need not add to what I have already said on this subject in the preceding section. 361. The furrows caused by the weft and the warp have not the inconvenience they present in the Gobelins tapestry. In fact, the regular grain of the tapestry for furniture is so far from producing a bad effect in the image represented on it, that we are obliged to give the appearance of this grain to many paper-hangings by means of parallel lines cutting it, or by points symmetrically placed.
