Technical Observations: There is a dark brown patina overall with localized areas of cupritic red, some patches of green, light gray (which is perhaps wax), and some friable dark brown material (perhaps burial accretions) in the recesses. The body of the fibula is in good condition, although the pin is missing, leaving traces of rust in the hinge area. The surface is worn down to the shiny golden metal on some of the high points.
Judging by the complexity of the model and the numerous undercuts, the body of the fibula was made by the lost-wax process and cast in one piece. The surface is somewhat concealed by the surface accretions. Texturing was probably already created in the wax stage as well and possibly reinforced in the metal.
