Ke Jiusi

Ke Jiusi (柯九思), courtesy name Jingzhong, also known by the pseudonyms Danqiusheng and Wuyun geli, was born in 1290, by most accounts in Zhejiang, and died in 1343 according to most major reference sources, though one academic dissertation cites 1349. He was active during the Yuan dynasty (1271 to 1368) and served as a leading connoisseur and curator of the imperial art collection, a role that placed him at the center of court taste in painting, calligraphy, and poetry. He is best known for ink bamboo painting, a genre in which he was regarded as a faithful and scholarly follower of the Northern Song master Wen Tong, copying and reinterpreting Wen Tong's models as a way of studying antique painting.

Official Yuan-dynasty history contains no detailed individual biography of Ke Jiusi. A University of Hong Kong dissertation on his bamboo paintings notes that he entered the Yuan dynasty's National College (Guozixue) as a student; beyond this, no further school, degree, or course of training is documented, and what else is known comes instead from his works, their inscriptions and seals, and later museum and auction scholarship. He should not be confused with a same-named character in the Chinese web novel "I Shall Seal the Heavens," a work of fiction unrelated to the historical Yuan-dynasty artist described here.

The Metropolitan Museum of Art, which holds his hanging scroll "Bamboo copied after Wen Tong" (dated 1343), describes him as a leading connoisseur and curator of the imperial art collection whose copying of Wen Tong reflects a scholarly approach to antique models. Beyond institutional museum description, no verbatim, critic-signed assessment of his work in a major outlet could be confirmed. Academic treatment of Ke Jiusi, including a dedicated dissertation at the University of Hong Kong on his ink bamboo painting within the Yuan dynasty, situates him as one of the most important bamboo painters of the period, prized for technical fidelity to the Wen Tong tradition and for his standing as an arbiter of court taste.

Ke Jiusi's market is thin and attribution-driven rather than benchmarked to a single, well-documented record sale. Public auction-database tallies vary: Artprice cites 25 auction results, Artnet lists 43, and LotSearch lists 34 lots under the reversed name Jiusi Ke. MutualArt has reported realized prices reaching as high as USD 1,186,026 for paintings and USD 859,723 for works on paper, though these figures are aggregate summaries rather than a confirmed single top lot with a named work, exact sale date, and auction house. Christie's has offered at least one significant hanging scroll, "Bamboo," catalogued as attributed to Ke Jiusi, but the publicly visible listing does not disclose a realized price or sale date. As of this writing, no single all-time auction record for Ke Jiusi, complete with work, price, currency, house, and date, can be reliably confirmed from public sources.

Works attributed to Ke Jiusi carry real attribution risk. No catalogue raisonne exists, official biography is sparse, and even major auction houses routinely catalogue lots as "attributed to" rather than firmly authenticated, which means provenance, seals, and inscriptions matter more than for artists with a settled modern market record. Reported price figures vary widely by source and are not tied to a single, fully documented record sale, so any specific number should be treated as indicative rather than definitive. Collectors should also be careful with the name itself: auction databases list the artist under both "Ke Jiusi" and the reversed "Jiusi Ke," and the name is unrelated to a same-named character in contemporary web fiction.
