The World on Mercator's Projection - c. 1890 
Single Click to Enlarge/Reduce
Antique printed color map of the world by an unknown maker, circa 1890. The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569. It became the standard map projection for nautical purposes because of its ability to represent lines of constant course, known as rhumb lines or loxodromes, as straight segments that conserve the angles with the meridians. While the linear scale is equal in all directions around any point, thus preserving the angles and the shapes of small objects (which makes the projection conformal), the Mercator projection distorts the size of objects as the latitude increases from the Equator to the poles, where the scale becomes infinite. So, for example, landmasses such as Greenland and Antarctica appear much larger than they actually are relative to land masses near the equator, such as Central Africa (source: Wikipedia). Very good to excellent condition, with center fold as issued in atlas, approx. 16 x 22 inches to neatline.
