PROVENANCEwith Gallery Nishiyama, Nagoya, 1986.

NotesNomadic peoples from the frontiers of China, the Kushans, together with Scythians whom they encountered in southern Siberia, conquered the Greco-Bactrian kingdoms in modern Afghanistan. Once settled they absorbed many of the cultural traditions of the conquered Greco-Bactrians. Jewelry and other objects from the region, circa 1st century A.D., frequently display iconography adopted from the Mediterranean world. The Cupids riding on ketoi, or sea monsters, a Greek invention, as seen on the earrings presented here, are typical of this rich mingling of east and west. The fine quality of the granulation and the use of inlaid stones, normally garnet and turquoise, are also typical of the jewelry from this region and period. For a pair of clasps with Cupids riding on dolphins see no. 80 in F. Hiebert and P. Cambon, Afghanistan, Hidden Treasures from the National Museum, Kabul.
