Technical Observations: The patina is a raised, rough layer of black and gray. Small spots of green and red are also present in some areas. Some areas of the surface where the black layer has been lost or removed are well preserved. The rounded, stubby hands appear to be original to the casting rather than the result of damage or loss.
The object is a solid cast, probably from a model made directly in wax. The enlarged front of the trailing leg is irregular and appears to be a casting flaw caused by a bubble in the investment for the model. The facial features and the incised lines on the headdress appear to be made or enhanced by cold working.
