From 1405, in order to maintain and expand the Ming Dynasty's tributary system, Yongle Emperor Zhu Di (reigning 1402-1424) and Xuande Emperor Zhu Zhanji (reigning 1425-1435) ordered eunuch Zheng He to lead giant fleets across the seas. But soon after Zheng He's seventh and last voyage in the 1430s, the Ming emperors put an end to this activity and ordered all records of previous voyages to be destroyed. Chinese writer Luo Maodeng (罗懋登), knowing the history of some of these voyages, wished to preserve a record of them, but, conscious of the possible penalty, decided to record the facts "under a veil", in his 1597 novel, An Account of the Western World Voyage of the San Bao Eunuch (《三宝太监西洋记》). This is what Dr. Sheng-Wei Wang has concluded after reading and analysing Luo's novel. Her book, The last journey of the San Bao Eunuch, Admiral Zheng He, shows the methodology and evidential arguments by which she has sought to lift the veil and the conclusions she suggests, including the derivation of the complete trans-Atlantic navigational routes and timelines of that last journey and the idea that Zheng He's last expedition plausibly reached the ancient American Indian city, Cahokia, in the U.S. central Mississippi Valley in late autumn, 1433, long before Christopher Columbus set foot for the first time in the Americas. She supports the hotly debated view that Ming Chinese sailors and ships reached farther than previously accepted in modern times and calls for further research. She hopes this book will become an important step in bridging the gap in our understanding of ancient China-America history in the era before the Age of Discovery. An interesting contribution to an ongoing debate. This edition has 48 scattered b/w illustrations and 8 b/w plates.
