Constructionen in Stein
Constructionen in Stein is a German technical manual on stone construction by G. A. Breymann, published in 1849 by the Hoffmann'sche Verlags-Buchhandlung and held by the ETH-Bibliothek, aimed at builders and architecture students. Its plates are numbered engraved diagrams of masonry courses, stair geometry and stone block layouts, drawn in precise line with grey wash shading. A designer might take from them the clean grid logic of brick and ashlar bonds and the stepped, angular geometry of stairs.
