[KS] Earliest European account of Korea?

[Brother Anthony]

I am wondering if the 30 pages (pp 529-560) devoted to Korea in Volume 4 of  the "Description g?ographique, historique, chronologique, politique, et physique de l'empire de la Chine et de la Tartarie chinoise etc etc"   published in 1736 by Jean-Baptiste Du Halde S.J., (1674-1743) consitute the earliest 'scholarly' account of Korea published in Europe (as opposed to the vivid anecdotes of Hamel) and whether everyone realizes that the book is available online at the Internet Archive in various formats (including PDG) ?  See  : http://www.archive.org/details/descriptiongog04duha   Obviously Chinese works are cited as the main source for the historical account but who was "Pere Regis" whose Memoires are given as the source of the geographical account pp529-537? 

I have added this and other books in French from the Internet Archive to my list of old books about Korea http://hompi.sogang.ac.kr/anthony/BooksKorea.htm
