Technical Observations: The patina is a crusty brown and green layer over a smooth green and crystalline red cuprite surface; there are a few areas of shiny black, brown, and bare metal. The fibula is largely intact with only minor losses to some edges.
The bow of the fibula was cast and then wrought to shape the spiral and form the pin. The knobs are hollow domes that were cast separately with their round pins. They were attached to the fibula body mechanically by inserting the pins through holes and hammering them over.
