Theatrum machinarum (i.e. machinarium) hydrotechnicarum, oder Schau-Platz der Wasser-Bau-Kunst ...
Theatrum machinarum hydrotechnicarum is a 1724 German treatise on hydraulic engineering by Jakob Leupold, printed by Christoph Zunkel and held by the ETH-Bibliothek. Its folding copper-plate pages show water machines, pumps, sluices, canal works and fortification layouts drawn in fine line with lettered figure keys. A designer could draw on the clean schematic linework, the cutaway views of machinery and the numbered plate layouts for technical diagrams.
