D. Henrici Glareani poetae laureati de geographia liber unus
A 1527 Basel geography treatise by the humanist poet Henricus Glareanus, printed by Ioannes Faber for scholars and students of cosmography. Its pictures are plain diagrams of spheres, circles and horizon lines, drawn with ruled strokes and letter labels, which a designer could use as sources for clean geometric schematic motifs.
