Technical Observations: The patina consists of a thin dark green and black layer with spots of light green and white accretions, which appear to be residue of investment material. No clear evidence of long-term burial exists. Some of the light green spots may have developed since manufacture. The bronze is a hollow lost-wax cast, presumably using an indirect technique. The bronze base is attached with screws and square nuts.
