1. Bought from Seaokue Yue [You Xiaoxi] 游筱溪, of Shanghai 上海. For price, see Original Miscellaneous List, p. 301. $100 for set. Said to have been excavated in Shensi [Shaanxi] 陝西.
2. (Undated Folder Sheet note) Original attribution: Chinese. Hsia [Xia] 夏. See further, S.I. 1318, Appendix VIII.
3. (John Ellerton Lodge, 1928) Late Chou [Zhou] 周.
4. (Isabel Ingram Mayer, 1945) Chou [Zhou] 周 dynasty or earlier.
5. (Undated Folder Sheet note) Sp. G. is 2.842.
6. (William B. Trousdale, 1964) Chou [Zhou] 周 dynasty. Western Chou [Zhou] 周, 9th--8th century BCE. Though undecorated, form is related to F1916.511 and F1917.380, and presumably of same date.
7. (Thomas Lawton, 1978) For an illustration of a similar jade plaque unearthed from a Liang chu [Liangzhu] 良渚 culture site in the Hangchou [Hangzhou] 杭州 Bay region of Chekiang [Zhejiang] 浙江 province, see Ch'en Tso fu [Chen Zuofu] 陳左夫, "Liang-chu ku-yu t'an-t'ao [Liangzhu guyu tantao] 良渚古玉探討," K'ao ku t'ung hsun [Kaogu tongxun] 考古通訊 1957.2, pl. 12:15. Although the Liang chu [Liangzhu] 良渚 culture is primarily a Neolithic culture, considered part of the Lung shan [Longshan] 龍山 Neolithic culture, its sites also yielded later artifacts, including Chou [Zhou] 周 and Han 漢 jades.
8. (Julia K. Murray, 1980) Attribution changed from Western Chou [Zhou] 周 to Neolithic, ca. 2000 BCE.
9. (Julia K. Murray, 1982) Plaques F1917.378c and F1917.378d are both closely related to the type of jade ornament belonging to the late phase of Liang chu [Liangzhu] 良渚 culture, represented by the excavated piece cited above by Lawton. Two other plaques in the Freer collection, which differ in being larger and in bearing surface decoration resembling demonic masks, are F1916.511 and F1917.380. All four plaques, however, seem intended to perform the same function, for all are drilled in back with three pairs of holes for attachment or stringing. In addition to being smaller than the two decorated plaques, F1917.378c and F1917.378d are also slightly different in their proportions, being wider relative to height.
