Drawings Or Sketches Of A Carpenter Compagnon Du Devoir 19th Century

These are drawings or blueprints made by a Compagnon du Devoir carpenter in the 19th century. Everything was done by hand and presents a set of plans for frames and staircases. This drawing will be delivered rolled (the drawings were rolled, we laid them flat to photograph them). For the condition, we note multiple tears, stains. For the Compagnons carpenters and stonemasons the heart of the transmission of knowledge and the study of projective geometry for cutting wood and stones, which is also called "descriptive" or, quite simply, the "Trait". To simplify, this method allows each of the parts making up a vault or a frame to be drawn according to its true size, which greatly facilitates the transition from design to execution. This "art of the Line", formerly more or less secret, has been transmitted since the 16th century by two channels: on the one hand, the publication of printed treatises and, on the other hand, the evening classes followed by the companions during their Tour de France.
