This is John Thomson's fascinating 1814 map of South America in its first edition. Covering the entire continent from the Caribbean Sea to Tierra del Fuego and the South Georgia Islands, this map reveals the continent on the cusp of its half-century struggle for independence. This map is full of often misleading detail, especially in the Orinoco, Paraguay, and Amazon River basins where many the missions, geographical formation, and indigenous tribes, suggest greater levels of exploration than hand in fact occurred. Though the persistent Laguna de Xarayes has finally been abandoned as a speculative source for the Paraguay River, Lake Parima, supposed site of Eldorado and apocryphal city of Manoa, figures prominently in Guiana. A dotted boundary line between Lake Parima and the coast identifies the limited of French Guiana by the Treaty of 1801. Lost in the dense mapping of rivers and mountain rangers are various annotations such as 'these lands are unknown,' 'these parts have never been explored,' and 'this country is uninhabited.' In general 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. Relief is shown by hachure with towns, cities, and major topographical features identified. Engraved in 1814 by J. Moffat of Edinburgh for issue as plate no. 54 in the 1817 edition of Thomson's New General Atlas.
John Thomson (1777 - c. 1841) was a Scottish cartographer, publisher, and bookbinder active in Edinburgh during the early part of the 19th century. Thomson apprenticed under Edinburgh bookbinder Robert Alison. After his apprenticeship he briefly went into business with Abraham Thomson. Later the two parted ways, John Thomson segueing into maps and Abraham Thomson taking over the bookbinding portion of the business. Thomson is generally one of the leading publishers in the Edinburgh school of cartography which flourished from roughly 1800 to 1830. Thomson and his contemporaries (Pinkerton and 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 Thomson's New General Atlas, published from 1814 to 1821, the New Classical and Historical Atlas of 1829, and his 1830 Atlas of Scotland. The Atlas of Scotland, a work of groundbreaking detail and dedication would eventually bankrupt the Thomson firm in 1830, at which time their plates were sequestered by the court. The firm partially recovered in the subsequent year allowing Thomson to reclaim his printing plates in 1831, but filed again for bankruptcy in 1835, at which time most of his printing plates were sold to A. K. Johnston and Company. There is some suggestion that he continued to work as a bookbinder until 1841. Today, Thomson maps are becoming increasingly rare as they are highly admired for their impressive size, vivid hand coloration, and superb detail. More by this mapmaker...
