The shape of this vessel is based on a 13th-century Islamic metal form, first translated by Chinese potters during the 15th century. For the Ming prototype of this blue and white vase, compare with the ewer illustrated by J. Pope, Chinese Porcelains from the Ardebil Shrine, The Freer Gallery, Washington, 1966, pl. 54 (lower right), and the one sold in these Rooms, 31 October 1994, lot 548A.

Ko Tianminlou Collection, 1987, and illustrated in the Catalogue, no. 60; and another in the National Palace Museum, Taibei, illustrated in Blue-and-White Ware of the Ch'ing Dynasty, 1967, pl. 4.
