Ivory and bronze mounted iron knife. Graeco-Roman 3d-4th century A.D. Tlie 

 inherent stability of three different materials are shown in a single object. The iron 

 blade is almost completely converted to rust; the bronze lion is only superficially cor- 

 roded with malachite; the ivory figure is stained with copper green from the lion, and is 

 cracked and fissured, but it has lost little of its original modeling. Courtesy Dumbarton
