A very similar white jade pendant from the collection of Charlotte Horstmann is illustrated by J. Watt in Chinese Jades from Han to Ch'ing, The Asia Society, New York, 1980, p. 203, no. 201, where it has been dated to the Song or Ming dynasties. Watt describes the beasts, which are configured in a nearly identical manner to the current lot, as dragon-snakes, and notes that the uppermost animal is shown with mouth open and with rounded snout, traits which are shared with the current lot, and it is likely that the two may have come from the same workshop.
It is also interesting to compare the similarities in carving on the heads of the dragons on the current lot to those found on another white jade pendant dated to the mid-Qing period in the Palace Museum, Beijing, illustrated by Y. Boda and Jiu-fang Li, Chinese Jades Throughout the Ages, Hong Kong, 1996, no. 99.
