Hanns Schermer: Über Basteibau • ‘Feuerwerkbuch von 1420’ (Auszüge) • Rezeptsammlung u.a.
A late fifteenth-century German manuscript of military and technical notes, compiled around 1490 by Hanns Schermer for a military or artillery audience and held by Heidelberg University Library. The pages show pen-and-ink diagrams of gun carriages, wheeled wagons, and a fortified bastion or palisade wall, with German explanatory text in black-letter script. A designer might take from them the spare, diagrammatic linework of early technical drawing, with plain outlines, hatched shading on the wall, and handwritten captions set beside the drawings.
