Mit Kupfern und Vignetten
A German scientific textbook of 1805 published by Barth, written by Vieth and Barth, with copper engravings and vignettes for students of physics and mechanics. The four pictures are geometric and mechanical diagrams: a labelled cylinder with lettered points, a cylinder on a tripod beside a balance with a weight pan, a sheet of boat and water-current figures with lettered construction lines, and a curved arc with straight construction lines. A designer might take the clean, precise line-engraved lettering and the labelled diagram style as a model for technical figures.
