LATE SHANG/EARLY WESTERN ZHOU DYNASTY

This vessel appears to be similar to an example excavated from Shaanxi Liquan Xian illustrated by R.W. Bagley, Shang Ritual Bronzes in the Arthur M. Sackler Collections, 1987, p. 506, fig. 98.3, where the author notes that 'yu with diamond-and-boss decoration' were 'probably an invention of Anyang foundries' and continued to be fashionable into the Zhou dynasty. He further notes that many of the yu excavated from Shaanxi province have diamond-and-boss decoration.
