Technical Observations: The patina is dark green with areas of lighter green and black. Thick corrosion layers obscure any surface details. There are deep cracks in these layers, but the object is stable. One rear leg is lost; the other legs are short, but they terminate in what appear to be finished cast surfaces. Three legs have modern drill holes (1 mm in diameter) that may have assisted with a display mount.
The animal’s features are asymmetrical and rather freely formed, and the wax model for this solid casting was probably made directly in the wax rather than cast in a mold. The surface is not preserved adequately enough to determine if any cold working was used in the finishing process.
