字書
During 1583-88, Michele Ruggieri, with Matteo Ricci as co-author, created a Portuguese-Chinese dictionary - the first ever European-Chinese dictionary, for which they developed a consistent system for transcribing Chinese words in Latin alphabet. The dictionary's Romanisation was Ruggieri's. A Chinese Jesuit Lay Brother Sebastiano Fernandez, who had grown up and been trained in Macau, assisted in this work. Unfortunately, the manuscript was misplaced in the Jesuit Archives in Rome, and re-discovered only in 1934, by Pasquale d'Elia. This dictionary was finally published in 2001.
