Royaume de Corée.

One of the earliest separate maps of Korea. The map engraved by the master engraver Delahaye, with a quite elaborately pictorial cartouche, engraved by G.Kondet.
Jean Baptiste Bourguignon d' Anville (1697-1782), a French cartographer who compiled over 200 maps. This state of the map is from the very rare Atlas Volume of "Histoire générale de la Chine, ou Annales de cet empire, traduites du Tong-Kien-Kang-Mou, par (...) J.A.M. de Moyriac de Mailla, jésuite françois (...): publiées par l'abbé Grosier (...): revues & publiées par Le Roux des Hautesrayes" and published in 1785.
The text volumes are a reissue of the d'Anville's description of China. The maps are printed from the same copper plates. In upper left corner "N°40 Description gén. De la Chine pag 177".

The map being the first accurate cartographic depiction available in the western world.
Since the Jesuits were not allowed in Korea the "Tartar lord" (Mukedeng a troubleshooter and trusted assistant for the Kangxi emperor) made measurements and observations in the Manchurian and Korean regions in 1709 and 1710. He was accompanied by father Jean-Baptiste Regis (1664-1738), Father Pierre Jartoux (1669-1720) and Erhernberg Xavier Fridelli (1643-1743) While in Korea the team was under constant surveillance. The Tartar lord was however given a map, and father Jean-Baptiste Regis produced a map that came out in the Kangxi atlas and was than used and edited by d'Anville and published in 1735 in du Halde (description de la Chine) and as "Royaume de Coree" (atlas de la Chine 1737).

The map is important as it shows Dokdo as "Tchian-chan-tao," which is a Chinese pronunciation of "Usando," an old name of Dokdo, together with "Fan-ling-tao," a Chinese name for Ulleungdo Island. Korea is spelled by several names, including "Kaoli Koue" (country of Goryeo), "Royaume de Coree" (Kingdom of Korea) and "Tchao-Sien".
The map also gave reasonably accurate nomenclature of all eight provinces of Korea: "King-ki" (Gyeonggi-do Province), Kin Chan (Gyeongsang-do Province), "Hoang-hai" (Hwanghae-do Province), "Kiang-Yuen" (Gangwon-do Province), "Ping-Ngan" (Pyeongan-do Province) and "Hien-King" (Hamgyeong-do Province).
There are also faithful transcriptions of the regions around Seoul, including Cao-yang (Goyang) and "Yong haing" (Yangpyeong).

Du Halde was a French Jesuit, and geographer of Paris.
Despite the broadening of the southern part of the peninsula, this map was in the main accurate and was widely copied in the next 150 years (McCune 1977 and Korea through western cartographic eyes ).
