Inventaire général des richesses d'art de la France
A French state inventory of national art treasures, published in Paris in 1876 by E. Plon for the Ministry of Public Instruction. Its single picture is a black-and-white ground plan of a cathedral-like church, with labelled chapels, transepts, nave and choir drawn in fine line, which a designer could use as a precise architectural diagram or a source for radiating geometric layouts.
