Praktische Anweisung zur Wasserbaukunst : welche eine Anleitung zur Entwerfung, Veranschlagung und Ausführung der am gewöhnlichsten vorkommenden Wasserbaue enthält
A practical German hydraulic engineering manual by David Gilly and Johann Albert Eytelwein, published in Berlin in 1802 for builders and engineers working on water construction. Its plates are numbered technical drawings of coffer dams, pile driving frames, sluices and timber cribs, drawn in fine line with cross-hatching and labelled figure numbers. A designer might take from them the clean, schematic diagram style of early engineering plates, with their grid of labelled views and sectional cutaways.
