Acta eruditorum. 1687
Acta eruditorum is a learned scholarly journal printed at Leipzig in 1687 by Grossius and Gletitsch for the scholarly public of Europe. Its plates are copper-engraved, one showing a dissected frog-like figure with numbered anatomical keys and the other a set of Roman coins with portrait busts and reverse designs, arranged in tidy grids with lettered figure labels that suggest a designer could borrow the clean rule-and-label layout.
