In China, the first cannon-barrel design portrayed in artwork was a stone sculpture dated to 1128 found in Sichuan province. The oldest extant cannon containing an inscription is a bronze cannon of China inscribed with the date, "2nd year of the Dade era, Yuan Dynasty" (1298). The oldest confirmed extant cannon is the Heilongjiang hand cannon, dated to 1288 using contextual evidence. The "History of Yuan" records that in that year a rebellion of the Christian Mongol prince Nayan broke out and the Jurchen commander Li Ting who, along with a Korean brigade conscripted by Kublai Khan, suppressed Nayan's rebellion using hand cannons and portable bombards.
