L'architecture. Le passé.--Le présent
A French survey of architectural history and contemporary practice by Anatole de Baudot, published in Paris by H. Laurens in 1916 for architects and students. The plates are line drawings—here a Gothic apse in cross-section, showing vault ribs, flying buttresses, pinnacles and tracery with tiny scale figures—usable as clean linework for structural diagrams and ornament studies.
