Found in a baked brick box beneath the foundation of the Temple of Enki, at Ur. This statuette and tablet were inside one, of many, baked brick boxes found in the foundations of sites around southern Mesopotamia. They are one of the few that have been well-documented in an archeological context. The objects are made of soapstone and are inscribed. They would have been created during the time of Rim-Suen, the Amorite king of Larsa, 1900 BC.
