Cloisonné enamel moonflasks are surprisingly rare. The form, with two large circular 'canvases', permitted the craftsman greater ease to design complex decorative motifs. Compare with one decorated with rocks and peonies illustrated by Claudia Brown, Chinese Cloisonné, The Clague Collection, Phoenix Art Museum, 1980, pl. 46. Two smaller examples are included in the National Palace Museum exhibition, Enamel Ware in the Ming and Ch'ing Dynasties, 1999, and illustrated in the Catalogue, no. 65, designed with a scene from the "Ode on the Red Cliff" (46 cm. high); and no. 66 with a depiction of spring cultivation (46.8 cm. high).
