LONDON - A stunningly beautiful flask made for the Qianlong Emperor and hidden for a century will be sold at Bonhams on 7th November 2013.

The turquoise vase with its rampant red Imperial dragon is estimated to command a price of £500,000 to £800,000 because of its rarity, beauty, and its Imperial provenance, says Colin Sheaf, Bonhams Asia Chairman. This flask is one of less than five such vessels known made for the Qianlong Emperor, who reigned from 1736 to 1795. A distinguished connoisseur of ceramics in his own right, the Qianlong Emperor presided over one of the greatest flowerings of Chinese art production, and pieces from this period are amongst the most highly sought-after today.

This flat-sided full-bodied flask – round like the moon, hence its name 'moonflask' in English and 'baoyueping' or 'bianhu' in Chinese– is also traditionally known as a 'pilgrim's flask' in the West, since it takes its form from a Middle Eastern prototype for water flasks, which were often carried by travellers. The auspicious five-clawed Imperial dragon flying amongst clouds follows a traditional design dating back to the 14th century.

Collected in China by Captain Charles Oswald Liddell (1854-1941), the vase was brought back to England by him to his country house Shirenewton Hall, a Grade II listed house near Chepstow in Monmouthshire. The Liddell home provided a suitably impressive setting for this Chinese treasure, surrounded by parkland with views over the 'Golden Valley', the Bristol Channel and beyond to the Mendip and Quantock Hills.

Colin Sheaf who has headed Bonhams Chinese Art Department for more than a decade says: "The reappearance of this flask, unknown to collectors for nearly a century, is a very exciting event in the world of Chinese art."

Captain Liddell was based in China from 1877 to 1913, running his family's firm for more than three decades whilst also developing his eye for and knowledge of Chinese art. He was fortunate to be present at a crossroads in Chinese history, just as 2,000 years of Imperial power was ending and Imperial pieces were becoming available to Western collectors astonished by their beauty. On his return from China, Captain Liddell created a Japanese Garden and erected an immense 1.5 tonne temple bell under a pagoda roof on the east lawn, reflecting his appreciation of Asian cultures.

Flasks of this type are much sought after by the world's leading museums for the extremely rare decorative style combining underglaze painting in cobalt-blue and copper-red minerals further enhanced by a fine translucent turquoise glaze. An artistic and technological triumph, it is expected to be fought over by the new generation of collectors emerging from China, eager to acquire a piece of Imperial history and willing to pay exceptional prices for such exceptionally rare treasures.
