Le secret d'architecture découurant fidelement les traits geometriques, couppes, et derobemens necessaires dans les bastiments : enrichi d'un grand nombre de figures ...
Le secret d'architecture is a 1642 French stereotomy treatise by Mathurin Jousse, printed at La Flèche by George Griveau for masons and builders learning to cut stone. The pictures are dense geometric plates of arches, vaults, and squared stone blocks with lettered points, dashed hidden lines, and measured constructions. A designer might take from them the clean hand-drawn logic of vault projections and the way overlapping construction arcs and hatched cut faces describe three-dimensional form.
