Technical Observations: The patina is a very smooth black with a thin green layer in some areas. Blue is also present at the interior, along with brown burial accretions. The hole at the throat near the bottom is a casting flaw.
The object is stable, and the surface is extremely well preserved in many areas. The smooth, irregular shapes suggest that the model was made directly in the wax. There is a depression on the reverse of the head that corresponds to the nose, so it is possible that a sheet of wax was pressed into a mold to make the general shape of the face. The back is open, and the edges of the metal are thinner at the opening, showing that the wax sheet was wrapped around a core and pressed thinner at the back up to the point of the opening. Two straps of wax were added to span the opening, perhaps for additional strength, and two loops were added to assist with mounting.
