Technical Observations: The patina is dark green with areas of light green and red. Deep-seated corrosion is indicative of long-term burial. The surface is damaged from corrosion and scratch marks are present in many areas from cleaning the surface.
The base section was cast integrally with the cat. The interior surfaces do not match the contours of the exterior relief, and it seems likely that the wax model was formed directly around a prepared core. A portion of what appears to be core is intact. It is white and contains large quartz grains and black charcoal particles. The inscription at the base is composed of soft broad shapes and must have been made in the wax model. Details in the face and ears are sharp and crisp and were made in the metal.
