Description: This hand colored map is a steel plate engraving, dating to 1813 by the important English mapmaker John Thomson. It is an early and historically important representation of the continent of Africa. Much of the continent is simply labeled “unknown parts”. Those sections that are known are surprisingly detailed. Caravan routes, temples, and even the distances between Oases are generally noted. Across the center of the continent Thomson details the mythical mountain range known as the “Mountains of the Moon”. The mountains of the moon were first postulated by Ptolemy to be the source of the Nile. This mysterious range remained on maps until the mid 19th century explorations of Burton, Speke, and Livingstone. Today it is generally agreed that references to the Mountains of the Moon refer to the Ruwenzori Range of Kenya & Uganda. This mountain range remains one of the most remote and exotic places on Earth, and is the home of a diversity of bizarre plant and animal life. However, it is not, as postulated, the source of the Nile which lies just to the south in Lake Victoria. Neither Lake Victoria nor Lake Tanganyika, which appear in much earlier Bleau maps, appear on this map. Thomson maps are known for their stunning color, awe inspiring size, and magnificent detail. Thomson’s work, including this map, represents some of the finest cartographic art of the 19th century.

Cartographer: John Thomson was one of the leading masters of the Edinburgh school of cartography which flourished from roughly 1800 to 1830. Thomson & his contemporaries (Pinkerton & Cary) redefined European cartography by abandoning typical 18th century decorative elements such as elaborate title cartouches and fantastic beasts in favor of detail and accuracy. Thomson's principle works include the "Thomson's New General Atlas" published from 1814 to 1827 and his "Atlas of Scotland". The "Atlas of Scotland", a work of groundbreaking detail and dedication would eventually bankrupt the Thomson firm in 1830. Today Thomson maps are becoming increasingly rare as they are highly admired for their monumental size, vivid hand coloration, and superb detail. Click here for a list of rare maps from John Thomson.
