With a blue-green patina, circular and dome-shaped, the symetric decoration shared in two expression areas; one presenting a band of alternated spirals and grains design, surrounding and enhancing the decoration of the other, central and heightened; its more marked relief seems to make it emerge of material its entrelaced snakes decoration with “wolves heads”, of which the clawed paws sticking themselves to their muzzles, is lively; it whirls and resounds with the frieze.
The spiral design is a classical motif we find into the “Tagars” nomadic culture to the North on the “Yenisei” river, with the grains pattern, besides recurring at the late Spring and Autumn and early Warring States periods. The “wolves masks”, for their part, are widely diffused in the Ordos region. The handling of this piece, filled with the art of the steppe riders and echoing to the last “Rong” barbarians, also akin to “Lyu” style of the Shanxi Houma foundry, of which the influence inside the Jin kingdom 晋国, was nomadic.
