The design of the central medallion and of the unusual floral sprays around the cavetto are Qing dynasty adaptations of a Chenghua prototype. Compare the present lot with a small doucai Chenghua-marked saucer from the Percival David Foundation, London, illustrated by R. Scott, Flawless Porcelains: Imperial Ceramics from the Reign of the Chenghua Emperor, Singapore, 1995, pl. 25. The Ming dynasty prototype has a central medallion with interlinked ruyi-heads, while the exterior is enhanced by lingzhi sprays. Now more elaborate, the Cheng-hua inspiration is nevertheless evident.
