Matteo Ricci
The Shanhai Yudi Quantu is known to have been highly influenced by the Jesuit missions in China, starting with the work of Matteo Ricci. Matteo Ricci himself had two of his own maps entitled "Shanhai Yudi Quantu": one engraved by Wu Zhongming (, "Wú Zhōngmíng") and dated 1600 and another engraved by Guo Zizhang (, "Gūo Zĭzhāng") and dated 1604.
