QIANLONG SIX-CHARACTER SEAL MARK IN UNDERGLAZE BLUE AND OF THE PERIOD (1736-1795) The vase is exquisitely painted around the globular body with a continuous scene depicting an elaborate architectural complex with pavilions and a gate, all nestled in a mountainous landscape, with a bridge arching over a flowing river which extends to the other side of the vase, detailed with a canopied boat carrying two scholars, below a poetic inscription rendered in black enamels, followed by two iron-red seals reading Qian and Long, all between two rows of relief-moulded chrysanthemum petals around the shoulder and above the foot. The slightly waisted neck is decorated with florettes on a bright yellow ground enclosed within upright lappets, below a band of trefoils enclosing florettes, all against a ruby-red sgraffito ground further decorated with detached lotus sprays. The rims and raised bands gilt decorated. The base is applied with turquoise enamels reserving the reign mark in underglaze blue in the centre. 7 1/2 in. (19.1 cm.) high, box
