Fascinating study of the prevailing theories regarding the Northeast Coast of Asia during the second half of the 18th Century, prepared by Diderot. The 10 maps which accompany the supplement to Diderot's Encyclopedia are one of the earliest studies of comparative cartography, compiling the most modern variant theories and setting them out side by side or in a series of maps. This set of 3 maps focuses on the 3 theories of the NE Coast of Asia as reported by various German & Russian explorers. The NE Passage is the focal point of this map, contasting the reports of three 18th Century cartographers.
Didier Robert de Vaugondy (ca. 1723-1786) was the son of prominent geographer Gilles Robert de Vaugondy and Didier carried on his father’s impressive work. Together, they published their best-known work, the Atlas Universel (1757). The atlas took fifteen years to create and was released in a folio and ¾ folio edition; both are rare and highly sought-after today. Together and individually, father and son were known for their exactitude and depth of research.
Like his father, Didier served as geographer to King Louis XV. He was especially recognized for his skills in globe making; for example, a pair of his globes made for the Marquise de Pompadour are today in the collection of the Municipal Museum of Chartres. Didier was also the geographer to the Duke of Lorraine. In 1773, he was appointed royal censor in charge of monitoring the information published in geography texts, navigational tracts, and travel accounts.
