Compare with a six-lobed white agate bowl with yellow thread inclusions dated to the same period, excavated at Qingheman, Fuxin County, Liaoning Province, now in the Liaoning Musuem, illustrated in Zhongguo Yuqi Quanji, Sui, Tang - Ming, vol. 5, Hebei Meishu Chubanshe, 1993, no. 139. Lobed bowls of this type appeared as early as the Tang dynasty, cf. smaller examples excavated from Hejiachun, Xi'ang, both illustrated ibid., nos. 25 (9.9 cm. wide) and 25 (9.3 cm. wide). The first excavated example, relating closely to the present bowl, is carved of white jade, fluted with eight lobes, and carved in shallow relief on the exterior with flower scrolls, although it is raised on a splayed foot ring. The second excavated bowl is scallop-shaped, and carved of rock crystal.
The carving of the phoenix with its prominent hooked beak and both wings outspread, is comparable to the designs found on Liao period jewellery, such as the crown illustrated by E. C. Bunker, et. al., Adornment for the Body and Soul - Ancient Chinese Ornaments from the Mengdiexuan Collection, University of Hong Kong, 1999, no. 91. It has been mentioned that the sharply hooked beaks are typical of the Liao phoenixes, and may have derived from the Qidan obsession with falconry, ibid., p. 223.
