Lehrbuch der gotischen Konstruktionen
Lehrbuch der gotischen Konstruktionen, a German textbook on Gothic building construction by Georg Gottlob Ungewitter, revised by K. Mohrmann, published in Leipzig by Tauchnitz in 1901 for architecture students and builders. Its plates are measured technical drawings of vaults, arches and rib intersections, with numbered diagrams, cross-sections and plan views in fine ink line. A designer could draw on their precise geometric linework, hatched shading and layered arch profiles for structural or architectural patterns.
