Philosophical transactions, hoc est, Acta philosophica ... : Aliquam exhibentia notitiam praesentium incoeptorum, studiorum & laborum eorum, qui eruditi salutantur, in plerisque praecipuis mundi partibus / ab Henrico Oldenburgo ... Anglicè conscripta, & in Latinum versa à Johanne Sterpino. 1669.
This is a 1669 Latin edition of the Philosophical Transactions, a learned journal of scientific correspondence compiled by Henry Oldenburg, printed in Frankfurt for a scholarly readership. The pictures are geometric diagrams in a plain letterpress style: a lens-like oval figure, a semicircle with lettered construction lines, and a hyperboloid solid with intersecting chords. A designer might take their clean line work and bold figure-ground contrast as a model for minimal scientific emblems.
