Stone is a rare material in New Guinea and virtually every stone sculpture known from there is of ancient origin. Many scholars believe that these enigmatic stone figures may have been used as hunting fetishes. This piece depicts an ancestor figure carved in relief on both sides. The head is large and naturalistic in comparison with the central section of the body, which shows a series of concentric ‘ribs’ enclosing the ‘heart’. Figures such as these may be early examples of the yipwons, the distinctive hook figures carved by the Yimam people of the Korewori River region in northeast New Guinea which play an important ritualistic role in hunting and warfare.
