While Jun water containers of this elegant form, apparently inspired by a lotus bud, are well known, the present example is distinguished by its unusually robust, rounded shape and the attractive horizontal cloud of dark bluish purple gracing the exterior. Jun vessels of this distinctive form are well represented in public and private collections, including some with their original covers, such as the example in the Palace Museum, Beijing, illustrated in The Complete Collection of Treasures of the Palace Museum - 32 - Porcelain of the Song Dynasty (I), Hong Kong, 1996, p. 242, no. 218, and one in the Metropolitan Museum of Art, illustrated by S. Valenstein, Handbook of Chinese Ceramics, New York, rev. ed. 1989, p. 87, no. 79. Other similar Jun jars are illustrated by J. Ayers, Baur Collection, Geneva, 1968, vol. I, no. A30; the Eumorfopoulos Collection, Catalogue, London, 1926, vol. II, pl. XXVI, no. B88; W. Hochstadter, Early Chinese Ceramics in the Buffalo Museum of Science, no. 62; in the exhibition of the Hong Kong Kau Chi Society, Ancient Chinese Ceramics, 1981, no. 25; and in the Museum of Fine Arts, Boston, illustrated in Oriental Ceramics, The World's Great Collections, vol. 10, Tokyo, 1980, no. 167.
