Géométrie descriptive : leçons données aux écoles normales, l'an 3 de la République
Monge's Géométrie descriptive, published in Paris by Baudouin in 1799, is a set of lecture notes from the teacher-training schools of the early French Republic. The plates are engraved geometric diagrams of circles, planes, cones and cylinders drawn with projection lines and construction marks. A designer could draw on their clean line work, rigorous linear grids and dashed auxiliary lines as a model for technical diagrams.
