12.5 x 14.5 in (31.75 x 36.83 cm)
A truly fascinating 1772 map of the northwestern parts of North America by Robert de Vaugondy and Thomas Jefferys. Essentially depicts the north eastern parts of Asia, speculations on northwestern America, and Admiral De Fonte's mythical conception of a Northwest Passage. Heavily based upon earlier work by Thomas Jefferys, Thomas Swaine Drage, Gerhard Muller, and James De Lisle. Vaugondy prepared this map prior to the voyages of James Cook to this region. Around this time Europe was rampant with speculation both regarding the existence of a Northwest Passage and the northwestern parts of America in general. The discoveries of Admiral de Fonte and Juan de Fuca though now known to be entirely mythical, inspired the European imagination.
Barthlomew de Fonte was supposedly a Spanish Admiral who, sailing up the Pacific coast c. 1640 discovered a series of gigantic lakes, seas, and rivers heading eastward towards the Hudson Bay. Supposedly, upon one of these great inland lakes, he met with a ship from Boston that claimed to have come through a Northwestern Passage. De Fonte's story appeared in a short lived 1706 English publication entitled 'Memoirs of the Curious.' The story inspired no less than Joseph-Nicholas de L'Isle, younger brother of the better known Guilleme de L'Isle. Joseph-Nicholas, at the time, was employed by the Russian Tzar Peter the Great in the compilation of Russian surveys and discoveries in Siberia and the extreme northeast of Asia. When he published his somewhat accurate map of northeast Asia, he paradoxically decided to include with it an entirely speculative map of North America based largely on De Fonte's letter. De L'Isle's mantle was later taken up by Jefferys, another ardent supporter of the De Fonte Northwest Passage theory, in his own map of the region, which was, ultimately, the inspiration for this map by Vaugondy.
In accord with De Fonte's suggestions this map displays the strait of Juan de Fuca continuing inland past the large lakes of Velasco, Belle and De Fonte to communicate with the Baffin and Hudson Bay. There are also a series of rivers and waterways connecting the lakes themselves to an outlet in the Arctic. Based upon Russian reports, Vaugondy renames the 'Straits of Ainan,' the 'Detroit de Bering,' paying homage to the great Russian navigator. Anian itself has been moved southward nearer to the Strait of Juan de Fuca. Anian is a term derived from a John Donne poem, 'Anyan if I go west by the North-West passage.' However, it was interpreted as the Bering Strait by cartographers, successfully transitioning it from the realms of poetry to cartography. Anian presupposed the existence of a Northwest Passage and, as such, was entirely mythical, though the lands that are now Alaska long bore that name. Further south still we find Quivira, one of the legendary northern American Kingdoms of Gold. Nearer to Russia the Aleutian Islands have been consolidated into a large peninsular landmass extending eastward towards Asia. In the extreme north, between 80 and 60 degrees of latitude is an archipelago, presumably discovered by Japanese sailors marooned in Kamtschatka, and purportedly inhabited entirely by pigmies. An altogether fascinating map of the Northwest Passage and the American west and a must for any serious collection dedicated to this region. Prepared by Vaugondy as plate no. 8 for the Supplement to Diderot's Encyclopédie.
Gilles (1688 - 1766) and Didier (c. 1723 - 1786) Robert de Vaugondy were map publishers, engravers, and cartographers active in Paris during the mid-18th century. The father and son team were the inheritors to the important Sanson cartographic firm whose stock supplied much of their initial material. Graduating from Sanson's map's Gilles, and more particularly Didier, began to produce their own substantial corpus of work. Vaugondys were well respected for the detail and accuracy of their maps in which they made excellent use of the considerable resources available in 18th century Paris to produce the most accurate and fantasy-free maps possible. The Vaugondys compiled each map based upon their own superior geographic knowledge, scholarly research, the journals of contemporary explorers and missionaries, and direct astronomical observation - moreover, unlike many cartographers of this period, they commonly took pains to reference their source material. Nevertheless, even in 18th century Paris geographical knowledge was severely limited - especially regarding those unexplored portions of the world, including the poles, the Pacific northwest of America, and the interior of Africa and South America. In these areas the Vaugondys, like their rivals De L'Isle and Buache, must be considered speculative geographers. Speculative geography was a genre of mapmaking that evolved in Europe, particularly Paris, in the middle to late 18th century. Cartographers in this genre would fill in unknown areas on their maps with speculations based upon their vast knowledge of cartography, personal geographical theories, and often dubious primary source material gathered by explorers and navigators. This approach, which attempted to use the known to validate the unknown, naturally engendered many rivalries. Vaugondy's feuds with other cartographers, most specifically Phillipe Buache, resulted in numerous conflicting papers being presented before the Academie des Sciences, of which both were members. The era of speculatively cartography effectively ended with the late 18th century explorations of Captain Cook, Jean Francois de Galaup de La Perouse, and George Vancouver.
Denis Diderot (October 5, 1713 - July 31, 1784) was a French Enlightenment era philosopher, publisher and writer. Diderot was born in the city of Langres, France and educated at the Lycée Louis le Grand where, in 1732, he earned a master of arts degree in philosophy. Diderot briefly considered careers in the clergy and in law, but in the end chose the more fiscally challenge course of a writer. Though well respected in philosophical circles Diderot was unable to obtain any of the government commissions that commonly supported his set and consequently spent much of his life in deep poverty. He is best known for his role in editing and producing the Encyclopédie . The Encyclopédie was one of the most revolutionary and impressive works of its time. Initially commissioned as a translation of Ephraim Chambers' Cyclopaedia, or Universal Dictionary of Arts and Sciences, Diderot instead turned into a much larger and entirely new work of monumental depth and scope. Diderot's Encyclopédie was intended to lay bare before the common man the intellectual mysteries of science, art and philosophy. This revolutionary mission was strongly opposed by the powers of the time who considered a learned middle class it a threat to their authority. In the course of the Encyclopédie production Diderot was imprisoned twice and the work itself was officially banned. Nonetheless, publication continued in response to a demand exceeding 4000 subscribers. The Encyclopédie was finally published in 1772 in 27 volumes. Following the publication of the Encyclopédie Diderot grew in fame but not in wealth. When the time came to dower his only surviving daughter, Angelique, Diderot could find no recourse save to sell his treasured library. In a move of largess, Catherine the II Russia sent an emissary to purchased the entire library on the condition that Diderot retain it in his possession and act as her "librarian" until she required it. When Diderot died of gastro-intestinal problems 1784, his heirs promptly sent his vast library to Catherine II who had it deposited at the Russian National Library, where it resides to this day.
Thomas Jefferys (1695 - November 20, 1771) was one of the most prominent and prolific map publishers and engravers of his day. Jefferys was born in Birmingham and was apprenticed to the engraver Emmanuel Bowen in 1735. Later, in the 1740s he engraved several maps for the popular periodical Gentleman's Magazine. Around 1740 Jefferys was finally able to go into business for himself and in 1746 received an appointment as 'Geographer to Fredrick, Prince of Wales,' which shortly after translated to the position of 'Royal Cartographer to King George III.' Jefferys initially specialized in compiling and re-engraving the works of earlier cartographers into more coherent cartographic wholes. Later, while not salaried position, Jefferys' appointment as 'Royal Cartographer' guaranteed preferential access to the most up to date cartographic material available, allowing him to produce new and updated charts of exceptional accuracy. He his best known for his maps of the Americas, particularly the posthumously published 1775 American Atlas, which included some of the finest and most important late colonial era maps of America ever made. Despite his prolific publishing history, royal appointments, and international publishing fame, Jefferys lived most of his life in dire economic straits. He was bailed out of bankruptcy by Robert Sayer during the production of the American Atlas. In the end, Jefferys died suddenly with very little to his name. Nonetheless, his cartographic legacy survived, and even after his death in 1771, many of his important maps continued to be published and republished by Sayer and Bennet, Conrad Lotter, Georges Louis Le Rouge, Laurie and Whittle, and others. Many attribute some of Jefferys best maps to the colorful and criminally inclined Irish cartographic genius Braddock Mead (John Green, c. 1688 - 1757), who is considered the 'secret behind Jefferys.' Jefferys was succeeded by his son, also Thomas, who had little success as a cartographer and eventually partnered with, then sold his stock and plates to William Faden - Jefferys' true heir.
