Technical Observations: The patina is blue and green with surface losses that reveal underlying red. Light brown burial accretions cover 25% of the surface. The corrosion products are slightly rough in texture and hide any surface detail.
The bronze was cast from a wax model made by cutting the design in a wax sheet. The bottom-edge surface does not reveal adequate detail to determine whether or not it is a fracture. It is similar in appearance to the other edges. No means of attachment to the lost section are visible.
