Technical Observations: The patina is a mottled light to dark green with some brown. In some areas where the top layer has popped off, reddish cuprite is visible, which is good evidence of long-term burial. The small black flecks are copper sulfide crystals that result from post-excavation storage conditions. There are also some tan burial accretions.
This circular belt buckle is made up of a ring and a bent tongue component. The large cast ring has a slight ridge on the center of the exterior and is oblong in section. The tongue is formed from a piece of copper alloy hammered flat at one end and bent around the ring. The surface of the tongue is slightly less corroded, and tool marks are more readily visible. The coarsely parallel striations on the tongue are the result of the smoothing process. The steps in the relief elements were created with chisel blows to splay the metal.
