This ritual bronze vessels created during China's Shang dynasty are extremely rare example of a set made up of three pieces.

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. With the one from the collection of The British Museum, the only two extant examples of double-ram zun are confirmed in the world.
