Wonderful world: Mercator's Atlas, 1613
Gerardus Mercator (1512-1594) was an engraver, craftsman, mathematician and cartographer, born in 1512 in Flanders. His best-known work was this volume of maps, the first to have borne the name ‘Atlas’ after the Titan of ancient Greek myth, who was said to hold up the world on his shoulders.
In 1569, Mercator devised a rectangular map with straight lines of latitude and longitude crossing at right angles, intended to be a new way of representing a round globe on a flat sheet of paper. This ‘Mercator Projection’ swiftly became the standard map projection used for nautical purposes, because of its ability to represent sailing routes of constant course as straight lines. Although the Mercator projection uses a linear scale which is equal in all directions, it does exaggerate the size of landmasses near the poles, making countries such as Greenland appear far larger than they really are. Despite this, Mercator’s map became the most widely used projection in the world and is still used today.
After Mercator’s death in 1594, his family sold the original engraving plates to many of his maps. These were bought in 1604 by the Belgian publisher and engraver Jodocus Hondius. Mercator’s work had, for some time, been overshadowed by that of Abraham Ortelius. It was Hondius who brought Mercator back into public recognition by printing this lavishly coloured volume of Mercator’s maps, produced in Amsterdam 1613. Hondius embellished Mercator’s original work, updating his maps and even contributing thirty-six new ones himself. The final work was credited to Mercator alone, but the image below shows the collaborative nature of the project, featuring Mercator and Hondius seated together surrounded by globes and cartographical instruments.
The dog seen below is the printer’s mark of Hondius, and acts as a ‘rebus’ or an allusional device that uses an image as a play on words: in this case ‘hound’ for Hondius. The globe bears the motto ‘I use, I describe, I adorn, I censure and I choose faithfully’ representing the scholarly and artistic merits of this atlas.
This atlas, along with many other items tracing the history of exploration and map-making from the 13th century onwards, can be seen in the Old Library on Saturday 15 March from 10:00-16:00 as part of the Cambridge Science Festival.
