Henrici Glareani Heluetii, poetae laureati de geographia liber unus,
Henricus Glareanus, a Swiss-born poet laureate, wrote this 1551 Latin geography treatise printed at Freiburg im Breisgau by Stephanus Grauius for scholars and students. Its pictures are plain geometric diagrams: a divided circle, concentric rings with lettered points, a semicircle with parallel rays, and a compass rose of wind names, useful for studying clean line-based schematic layouts.
