A fine blue and white cylindrical bottle vase seal mark and period of Qianlong

the body of gently tapered form decorated with ten gently lobed panels each enclosing alternating blooms of camellia and peony on long leafy stems vibrantly painted in underglaze blue, between leafy floret scroll bands and classic scroll band around the foot, the slightly convex sloping shoulder with a band of lappets below a formal scroll, supporting a tall cylindrical neck painted with leafy peony stems below a classic scroll around the rim, the base inscribed with a six-character seal mark in underglaze blue 

A similar vase is illustrated in Suzanne G. Valenstein, A Handbook of Chinese Ceramics, New York, 1975, pl. 159; another was included in the exhibition Chinese Ceramics, The S. C. Ko Tianminlou Collection, Hong Kong Museum of Art, Hong Kong, 1987, cat. no.60; and a third in the National Palace Museum, Taipei, is illustrated in Blue-and-White Ware of the Ch’ing Dynasty, Book II, Hong Kong, 1967, pl. 4. 

The shape of this vessel is based on a 13^th century Islamic metal form, first translated by Chinese potters during the 15^th century.  For the Ming prototype of this blue and white vase, see a ewer illustrated in J. Pope, Chinese Porcelains from the Ardebil Shrine, Washington, 1966, pl. 54 (lower right).
