Duisberg: Gerard Mercator.
Map. Uncolored engraving. Image measures 13.75" x 18", page measures 17.25" x 21".
Exquisite map of Scotland circa 1590, with Latin text on the back. Mercator (1512-1594) was an accomplished mathematician, cartographer, globe maker and engraver but is best known for the Mercator Projection. Incorporating the newly accepted fact that the world is round, Mercator was able to render longitude lines consistently straight on a chart. Although this requires some distortion, it was of great use for navigators, and is historically important, as it is still the most commonly used projection today. Full original margins, minor foxing.
Condition: Very Good
