"These impressive volumes were published as part of the 'Description des arts et métiers.' The plates, many of which are folding, are engraved by Gardete, Goussier and others, and depict organ design and construction in elaborate detail as well as illustrating a number of other keyboard instruments and a hurdy-gurdy; of particular note is the very large folding plate of an organ built by Gabler in 1750, with a fine view of the interior of the Abbey at Weingarthen."
"Bédos de Celles is best known for his writings, particularly his L'art du facteur d'orgues. This work is among the earliest to describe in detail the design and physical construction of the pipe organ and provides a valuable description of classical French organ building. His extensive and highly detailed plates, charts and diagrams deal with aspects of organ design, mixture compositions, pipe scales, pipes and pipe making, and tools and their use. Working from the writings of Marie Dominique Joseph Engramelle, he gave exhaustive instructions on the transfer of musical scores to organ barrels for mechanical playing and provided two complete pieces in the form of pinning charts. This aspect of his work inspired the makers of mechanical organs from his time forward. Bédos de Celles also described a mechanism for a square piano combined with an organ, a claviorgan and a vielle organisée and included a detailed discussion of ornamentation, articulation and principles of organ registration."
