Four-fingered dragon on the Nine Dragon Screen of Datong, China. While five-fingered dragons were only for the emperor, four-fingered dragons were for other members of the imperial family. In this case, the dragon screen was built in the late 14th century at the palace of Zhu Gui, thirteenth son of the Ming dynasty’s first emperor, Zhu Yuanzhang. Photo by Renée DeVoe Mertz.
