Dictionarium Annamiticum Lusitanum et Latinum

While browsing through the French version of Wkipedia today, I found the digitalized version of Alexandre de Rhodes' monumental work Dictionarium annamiticum seu tunquinense lusitanum et latinum on the website of Biblioteca Nacional de Portugal.

Based on the works of Gaspar de Amaral and Antonio Barbósa, the jesuit Alexandre de Rhodes' Vietnamese-Portuguese-Latin dictionary is one of the first important works that uses the quốc ngữ writing system.
