I will try to present a full selection of the Dubuisson plaque bindings on the next few pages, however I would like to present here first, a few examples which relate directly to the last few pages which concern the Collombat and Padeloup examples.
Comparative Diagram 1 - OSS palettes vs Dubuisson's Almanach Royal palettes
In Comparative Diagram 1, I have extracted the palettes from the Dubuisson bindings illustrated above, to compare them with the Office de le Semaine Sainte examples of the previous page. In as much as these examples have been taken from photos which are without an indicated scale, these extractions have been reproduced at an approximately similar scale. This same diagram must be repeated with scaled high resolution images, before one can claim for certain that these palettes have been made from the same tools. For the moment we can state only that they do look similar! Below I have reproduced an example of a Dubuisson plaque binding in which we see that plaque was smaller than the board to be decorated and thus an additional 'dentelle' had to be added to the top and bottom.
Comparative Diagram 2 - Dubuisson's Almanach Royal roulette and a Collombat 1743 Office de la Semaine sainte roulette
In Comparative Diagram 2, I present two roulette examples (reproduced at the same approximate scale), certainly they are slightly different however very similar in artistic conception. Both of these roulettes served as dentelle fill on boards where the plaque employed did not cover the entire surface. At this point I do not have proof that the all the plaques that we have been examining in the past few pages were made by Dubuisson, however the number very similar or identical elements found thus far, strongly suggests a very close Dubuisson connection.
In gathering these images from far and wide I discovered that there is not one good online source of information concerning the Dubuisson plaque bindings. Therefore I have decided to devote the next few pages to a sort of Dubuisson plaque inventory.
