Plate 286. Different Sorts of Sections Appropriate for Infilling Panels

This is an excerpt from “Roubo on Marquetry” by André-Jacob Roubo. Translation by Donald C. Williams, Michele Pietryka-Pagán & Philippe Lafargue. The translators’ additions to the text are in brackets. Roubo’s asides are in parentheses.

Figure 4 represents a composition with dice or cubes, placed on a background of whatever color; these dice or cubes are hexagons, placed side by side, in a manner such that their points touch each other, as you can see in this figure.

Each of these hexagons, or figures with six sides, is composed of three lozenges of any colors assembled together to make the dice or cubes appear in relief. Lozenge C (which is the daylight side) is an example of the shape in question and is made in rosewood. Lozenge D, which is the top of the cube, is of grey or yellow wood. Lozenge E, which is the shade side, is of violet wood. The remaining space [unmarked but primarily horizontal] is of some other wood that one judges appropriate, provided that it differs in the color of wood that forms the cubes. The cubes should not only differ in color from that of the bottom, but also each lozenge comprising the cube should all be different from each other. One accomplishes this by choosing pieces darker in color from one side to the other, or even by passing them over hot sand, as I will teach later.

Figure 5 represents another section, which does not differ from that of which I just spoke, except that it does not have any remaining space or background like the last one. To the contrary, all the dice or cubes fit one inside the other without leaving any void space, which works quite well. However, it is good to observe when making this last type of section, to make a space or background between the cubes on top and on the bottom, as I have shown in this figure, which works much better than to see the ends of cubes cut up, as one does ordinarily, and which I have indicated by line F–G.

In general, whether the sections of which I am speaking are with a background as in Fig. 4, or without a background, as in Fig. 5, it is necessary to take great care when making the section that a whole number of cubes is found on the length, and that the uppermost end of these same cubes reach the banding or stringwork that surrounds them, as I have shown here. This is very easy to do since it is only necessary to adjust the proportions of the cubes according to the need, it not being absolutely necessary that the hexagon of the cubes be perfectly regular. Whatever way it can be done is the better way, and is so much easier to do when the three lozenges that compose the hexagon are of a similar shape, which does not ordinarily happen when the hexagon is of an irregular shape.

If one does not wish to make dice or projecting cubes, as in Fig. 5, one could make sections of cubes to fill the lozenges in a unified wood, which does not work badly when the joints are well made, as one can see in this figure. [This is in fact my favorite manner of preparing a composition such as this. I find the subtlety much more to my taste, especially when using a wood with a fine grain pattern with a noticeable difference from early wood to late wood, such as bald cypress on the radial plane.]


Figure 6 represents a section with mixed stars, which is a section that is very complex in appearance; however, it is only hexagons, as that of H, I, L, M, N, O, which approach and penetrate each other, so that the point of whichever star, becomes the center of another. It is necessary to observe in making these sorts of sections that one finds, as much as possible, a number of hexagons complete in height as is found in this figure, so that the bottom or void remaining at the points of the stars be similar at the bottom as at the top, which could not be if the section bordered by the line P–Q , of which the distance to the top-most stringwork of the section, contains only one-and-a-half hexagons in height. As for the length of this type of section, taken in the direction that is represented in Fig. 6, it is not important only that the number of hexagons be complete. It suffices that no points of the stars be cut along the same line, so that this section be as perfect as is possible to be.

These sorts of sections can be made with a projecting appearance, or be filled with segments of the same wood, which is equal for the form and disposition of the joinery, which is always given by the parallel lines, horizontal and perpendicular, and [rather than being comprised of lozenges] by equilateral triangles, of which the tops are opposite one another. Inspecting this illustration alone is by itself better than all the explanations that one can give.

Fig-7.jpgFigure 7 represents another section, composed of octagons or figures with eight sides, placed in stars with eight sides, which all come to a point in the center. The stars that compose these sections touch each other on their perpendicular and horizontal faces at two points, which produces between them a squared space. This space is filled with the point of a diamond, as in the height of this figure, made from the background veneer. The other squared voids, which produce the return of the points of these same stars, being larger than those of which I just spoke above, are filled in by other stars with four points or some other element placed on the base, which distinguishes them from the rest of the work, as I have shown in the upper part of this figure, of which the stars as much as the points of the diamonds have an obvious [apparent] relief.

    Nice, and thanks Meghan. I don’t do marquetry as most of my stuff is of a more utilitarian nature, but I do greatly admire the workmanship involved. I also admire and appreciate the work you guys do in presenting materials that link the craft of today to that of generations past.
