A LARGE BLACKISH-GREEN JADE CEREMONIAL BLADE, ZHANG, EX-SACKLER COLLECTION Northwest China, late Neolithic period, c. 2000 BC. The thinly carved blade of gently waisted outline tapering from the two slightly projecting flanges (lan) towards the extremely thin curved end. The tang drilled with a hole. Provenance: A.W. Bahr Collection, Weybridge, 1963. Arthur M. Sackler, acquired from the above. Christie's London, 3 November 2009, lot 159 (part lot, together with another blackish-green zhang blade). Austrian private collection, acquired from the above. Two old inventory numbers, 'J1147' and 'J809'. Arthur Mitchell Sackler (1913-1987) was one of America's foremost art collectors, who amassed the largest Chinese art collection in the world. His name lives on in many art-related projects: the Sackler Wing that houses the Temple of Dendur at the Metropolitan Museum of Art, the Arthur M. Sackler Gallery at Princeton University, and the Arthur M. Sackler Museum at Harvard University. At the Smithsonian Institute, the Arthur M. Sackler Gallery is a museum for Asian and Near Eastern Art. In China, the Arthur M. Sackler Museum of Art and Archaeology teaches museology to students in Beijing. Published: 4000 Years of Chinese Archaic Jades, Prof. Filippo Salviati, 2017, page 121, no. 139. Condition: Excellent condition with minor wear. Two minute hairlines to the edge of the blade, where the stone is at its thinnest, few old losses to edges. Weight: 73.9 g Dimensions: Length 30 cm, Width 7 cm, Thickness 1.5-1.6 mm The stone is mostly translucent, though in many areas only when light is shone through from a short distance, turning red in those areas and greenish-yellow at the thinnest parts. The mineral is of a blackish-green color with a brownish tint and a creamy streak, which is entirely opaque, to both sides near the tang. The dark color is probably due to a very high presence of iron within the raw jade, which was specially selected to craft this specific type of blade and not used for other categories of jade artifacts. Ceremonial blades such as the present lot are rare. For an ancient drawing of such a blade, see Wu Dacheng, Gu Yu Tu Kao (Investigations into Ancient Jades with Illustrations), 1889, Shanghai, fig. 1. Literature comparison: Compare a closely related ceremonial blade in the collection of the Metropolitan Museum of Art, accession number 30.120.124. Compare also a slightly larger blade, also attributed to the Neolithic period, in the National Museum of China, Beijing, illustrated in National Museum of China, ed., Zhongguo Guojia Bowuguan guancang wenwu yanjiu congshu, Yuqijuan [Studies on the collections of the National Museum of China. Jade], Shanghai, 2007, pl. 25. For a full discussion of this type of blade, see Rawson, Chinese Jade, pp. 188-191.
