Drawing Or Blueprint Of A 19th-century Compagnon Du Devoir Carpenter.

This is a drawing or full-scale drawing created by a Compagnon du Devoir carpenter in the 19th century. It was entirely hand-drawn and presents a set of plans for timber frames and staircases dating from October 1866. This drawing will be delivered rolled (drawings were originally rolled; we have flattened them for photography). Regarding its condition, we note several tears along the edges and some stains in places. Among the Compagnons du Devoir carpenters and stonemasons, the core of knowledge transmission is the study of projective geometry for cutting wood and stone, also known as "descriptive" geometry or, simply, "drawing." In short, this method allows each component of a vault or timber frame to be drawn according to its true dimensions, greatly facilitating the transition from design to construction. This "art of drawing," once more or less secret, has been transmitted since the 16th century through two channels: firstly, the publication of printed treatises, and secondly, the evening classes attended by journeymen during their Tour de France (apprenticeship journey).
