An example of a tiger-shaped pendant in the British Museum, illustrated by J.Rawson in Chinese Jade from the Neolithic to the Ming, London, 1995, p. 91, fig. 86, and dating from the Ming dynasty, is based on a late Eastern Zhou jade prototype. The author explains that this form of tiger shown in profile, with its mouth agape and its haunches resting on its four clawed feet is the hu (tiger) from the Zhou Li, a text that would have been familiar to the educated classes in the Song, Yuan and Ming dynasties. The author also shows an illustration of an Eastern Zhou carving of a tiger pendant, fig. 87, similar to the Ming example, and states that later carvings are distinguishable not only because of their different proportions but also because they are much heavier than the original tiger pendants.
