大秦景教流行中国碑
"China Illustrata" emphasized the Christian elements of Chinese history, both real and imagined: the book noted the early presence of Nestorian Christians (with a Latin translation of the Nestorian Stele of Xi'an provided by Boym and his Chinese collaborator, Andrew Zheng), but also claimed that the Chinese were descended from the sons of Ham, that Confucius was Hermes Trismegistus/Moses and that the Chinese characters were abstracted hieroglyphs.
