Acta eruditorum. 1686
Acta eruditorum is a 1686 scholarly periodical published in Leipzig by Grossius and Gletitsch for the learned readership of its day. Its plates are geometric and mechanical diagrams: a plate labelled Tab IV with pulley and lever figures, a pendulum-like rig with a labelled cord, and a lettered triangle construction. A designer might draw on their precise line work, lettering, and schematic clarity.
