Technical Observations: The patina is dark brown and green. The piece is structurally sound, although pitted with porosity that is particularly visible at the back. The surface has been stripped, removing much of the corrosion products and resulting in the loss of some of the original surface detail. Some corrosion and burial accretions remain on the back.
The solid beard was cast by the lost-wax process in one piece, together with the large rectangular-sectioned tang that served to mount it to its deity’s chin. The tang may also have served as a sprue for casting. The slightly concave shape of the back of the beard is probably the result of forming the wax model in an open back mold. The neat, striated texture of the braided beard on the front was probably done in the wax.
