Archaistic jades were especially prized by the Qianlong Emperor, and certain designs were perpetuated throughout the Qing dynasty. The flat, ribbon-like dragons that appear on the present vase derive from designs found on Western Zhou bronze vessles and can be found on earlier Qianlong-period jade hu-form vessels, such as an imperial example in the Palace Museum, Beijing, illustrated in Zhongguo Yuqi Quanji - 6 - Qing, Hebi, 1991, p. 117, no. 182.
