Technical Observations: The patina is dark green with underlying areas of red. Brown and gray burial accretions are also present. The tail is broken off and lost. The surface is fairly well preserved. The bronze is solid cast from a model formed directly in the wax. Four cold-work punch marks decorate the sides of the ibex.
The ibex and hand have matching corrosion layers, supporting their association. The hammered wire connecting them is corroded and appears antique. It has lost much of its outer layers of corrosion, probably from flexing during handling.
