The themes in this Via Media book—drawn from Chinese history, culture, and martial arts experience—are entwined in a fictional narrative to animate events envisaged to have occurred during the mid-eighteenth century. From the outset, a thin veil separates fact from fiction. Our story starts with a discovery. While conducting research at the Vatican Library on the Jesuit missions in China, two scholars find a folder of papers written in Chinese among documents belonging to Giuseppe Castiglione (1688–1766), a painter at the royal court in Beijing. The papers turn out to be written by a fellow court painter, Yang Mingbin (c. 1664–1765). Yang’s handwritten essays provide revelations vital for understanding the ingenuity of Chinese martial arts.
