《利玛窦世界地图研究》中的“日本地图”是个译误,而利玛窦晚年自传中所谓的“日本纸”则是笔误。这两个错误似乎微不足道,但实际上关系到地图史、造纸史或印刷史上两个不小的问题。事实上,利玛窦“日本纸”的笔误已经引起了一定的混乱,但愿黄时鉴、龚缨晏的“日本地图”的译误不致同样以讹传讹。 The “Japanese map” in Ricci’s World Map Study is a translation error, while the so-called “Japanese paper” in Ricci’s later years autobiography is a clerical error. These two errors seem insignificant, but actually relate to two notable problems in the history of the map, paper or printing. In fact, the sketches of Matteo Ricci’s “Japanese paper” have caused some confusion, but I hope that the mistranslation of “Japan’s Map” by Huang Shijian and Gong Yingyan will not be erroneously repeated.
