Double-ram zun, bronze vessel in the shape of a jar flanked by the heads and forequarters of two rams, with curling and rounded horns, and bodies covered with a pattern of scales. Designs of animal masks fill the rectangular panels below the vessel opening. On the underside are a simi-circular loop at the centre and two pairs of C-shaped projections at the sides. This form, with a ram on each side of a cylindrical wine vessel (zun) with a wide mouth, is a rarity among the ritual vessels used to making offerings to the gods or ancestors in ancient China
