No other dragon head fitting made of painted lead appears to be published. Stylistically, however, the head is similar to the head of a dragon carved on a stone alcove ornament from Tianlongshan, dated Eastern Wei and illustrated in Ancient Chinese Arts in the Idemitsu Collection, Tokyo, 1989, no. 434. See, also, the gilt-bronze fitting dated late Six Dynasties included in the exhibition Chinese Works of Art, J.J. Lally & Co., 27 May - 18 June 1988, no. 41. The present example and the stone example have very similar eyes, rippled snout and elongated jaw, while the gilt-bronze example has similarly open, fanged jaws and fierce aspect.
