十八世紀 犀角雕獸柄山水紋杯

Provenance: a private European collection, acquired by repute circa 1950s, and thence by descent.

The present libation cup is a remarkable feat of carving and a successful example of the use of the libation cup as a canvas to depict painterly landscape scenes within shaped cartouches, most probably based on scroll paintings. This decorative design of landscape cartouches is familiar in porcelain vessels, which may have further served as inspiration for the master carver.
