This book, first published in 1875 and reissued in 1973, analyses the limited evidence from the works of early Chinese historians that explorers from China had discovered a country they called Fusang – possibly western America, and in all probability Mexico. The original document on which Chinese historians based their accounts of Fusang was the report of a Buddhist monk called Hoei-shin, who, in the year 499 AD, returned from a long journey to the east.

Charles Godfrey Leland (August 15, 1824 - March 20, 1903) was an American humorist and folklorist, born in Philadelphia, Pennsylvania. He was educated at Princeton University and in Europe.
Leland worked in journalism, travelled extensively, and became interested in folklore and folk linguistics, publishing books and articles on American and European languages and folk traditions. Leland worked in a wide variety of trades, achieved recognition as the author of the comic Hans Breitmann's Ballads, fought in two conflicts, and wrote what was to become a primary source text for Neopaganism half a century later, Aradia, or the Gospel of the Witches.
