Opusculum geographicum rarum, : totius eius negotii rationem, mira industria et breuitate complectens, iam recens ex diuersorum libris ac chartis, summa cura ac diligentia collectum & publicatum,
A 1590 Latin cosmography and geography treatise by Johannes Myritius, printed at Ingolstadt by the Eder press for scholars and readers of geographical works. Its pages show printed diagrams of the compass rose, a plain circle divided into eight sectors with lettered points, and an armillary sphere on a decorated stand, all set in dense black-letter text with ornamental headpieces. A designer could draw on these as clean, schematic instrument drawings, with their labelled rings and radiating lines suited to navigational or scientific graphics.
