Very similar scroll pattern incorporating circular 'eyes' and rolled snouts suggestive of dragon heads, can be found on a jade bead of more elongated proportions dated to the Eastern Zhou period, 5th century BC, illustrated by J. Rawson, Chinese Jades from the Neolithic to the Qing, British Museum, 1995, p. 274, fig. 17:17. The author suggests that beads of this type would "presumably have formed part of a complex of jades hung as a pendant from the waist". Similar scroll patterns can also be seen on the green jade hilt dated to the Eastern Zhou period, 6th-5th century BC, in the Hotung Collection, illustrated ibid., p. 64, fig. 45b, and on a jade bi and two cylindrical jade beads dated to the Warring States period illustrated by Bo Zhongmo in Guyu Jingying (The Art of Jade Carving in Ancient China), Taiwan, 1989-90, p. 113, fig. 44 and p. 116-7, figs. 47 (right) and 48 (right) respectively. Such surface designs were apparently influenced by fittings and rings made of gold, which had become widespread by the 8th century BC and which regularly appear in late Western Zhou tombs and in 8th-6th century BC tombs in Henan and Shaanxi.
