A closely related white-glazed bottle was sold in London, 8 June 1993, lot 13. Several similar phoenix-head bottle vases and ewers are published in Sekai Toji Zenshu, Vol. 12, Song, Shogakukan, Tokyo, 1977, p. 295, fig. 180, for a white-glazed similarly-shaped phoenix head ewer with two raised rings around the lower neck and the bird with open beak (37 cm. high), reproduced from Kominklijk Bataviaasch Genootschap van Kunsten en Wetenschappen, Jaarboek, 1933; p. 280, pl. 299, for an excavated 11th century white-glazed phoenix-head ewer with shorter neck and two raised rings around neck (20.2 cm. high); and p. 30, no. 24, for an 11th century white-glazed phoenix-head vase with very similar proportions to current vase, but with two raised rings around the lower neck (42.2 cm. high).
Cf. also the 10th-11th century white-glazed phoenix-head ewer with missing spout and with the bird's beak open, illustrated on the front cover of S. Vainker's Chinese Pottery and Porcelain From Prehistory to the Present, British Museum Press, London, 1991; and from the Tokyo National Museum's Special Exhibition Chinese Ceramics, Tokyo, 1994, p. 102, no. 148, a ewer very similar in style to the British Museum example, also with five raised rings around the neck, but with closed beak, ascribed by the authors to the Xicun kilns of Guangzhou, dated to the 11th century.
