A rhinoceros horn libation cup, 17th century

Finely carved as a lotus leaf rising from the bundled stems forming the handle and foot, the exterior carved with lotus blossoms, leaves, pods and cereal sheaves over the incised lotus-leaf veins, the interior carved with a pair of fish swimming along the sides of the cup, with fine scales and fins. 11cm (4¼in) across. Sold for £16,800

Note: A double fish (shuangyu) represents the blessing: May you be blessed with connubial bliss, fecundity and an abundance of good luck. A pair of fish is also symbolic of the joy of union and, due to the reproductive power, also the blessing of numerous offspring.
