The design of the present cup is based on the Ming prototype, such as an example, dated to the Yuan-Ming dynasty, in the Musée Guimet, Paris, included in the exhibition, Chinese Jade Throughout the Ages, and illustrated in Transactions of the Oriental Ceramic Society, 1973-75, no. 326. J. Ayers and J. Rawson noted that cups of this form first appeared in yingqing porcelain of the late Song period and remained popular throughout the Ming dynasty. Compare with a similar cup dated to the early Qing dynasty, illustrated by Yang Boda, Gu yu kao, no. 115.
