Acta eruditorum. 1688
Acta eruditorum is a learned scholarly journal issued in Leipzig in 1688 by the publishers Grossius and Gleditsch for the European scholarly community. Its plates are dense black-and-white copperplate engravings of scientific apparatus, a pump mechanism, and celestial or allegorical figures, with fine parallel hatching and tonal shading that a designer could study for line work and diagrammatic layout.
