This extremely rare and highly artistic Sumerian vessel is boldly modelled, with the sides decorated in a repeated relief of a lion attacking a bull. This motif was first seen in the Sumerian repertoire in the Uruk period.
The animals are carved in low relief whilst the heads, turned to face the viewer, are fully three-dimensional. Such extraordinary high relief sculpture developed at the end of the fourth millennium B.C., when cities emerged across Mesopotamia. Vessels of this type have been frequently found in palaces or religious structures, which suggest that they had a special function in such settings. After cylinder seals, they are the most important source of pictorial information for the period. The pictures are drawn from the natural realm, often portraying an ordered world of domesticated animals or, alternatively as in the case, the very real and vivid threat of potentially hostile creatures such as the lion.
