Henrici Glareani Helvetii poetae laureati de geographia liber unus
Henricus Glareanus, a Swiss poet laureate, wrote this Latin treatise on geography, printed in Venice in 1538 by Giovanni Antonio de Nicolini da Sabbio for a scholarly readership. Its pictures are geometric diagrams of spheres, circles and projections, with Latin letters and labels, showing how mathematical geography was drawn and could be reduced to simple rings, quadrants and compass-like dials.
