MID-LATE 17TH CENTURY

Shangjun is the zi of Zhou Bin, a native of Zhangzhou, Fujian province, who was a renowned carver of seal knobs, and is thought to have worked during the mid to late 17th century. For a discussion of Shangjun see, G. Tsang and Hugh Moss, Arts from the Scholar's Studio, Oriental Ceramic Society, Hong Kong, 1986, p. 84, where a pair of baifurong seals, also carved on top with formalized dragons reserved on a leiwen ground, and with an incised signature seal, Shangjun, is illustrated, p. 85, no. 43.
In the Literati Mode, Sydney L. Moss Ltd., London, 1986, p. 209, the author, Paul Moss, notes that seals by Jun are quite rare, and compares the seal to another thin seal of similar stone carved with comparable dragon design, which also bears the signature of Shangjun, which is in the author's collection.
