Technical Observations: The patina features uneven green, red, and black corrosion. The green appears in the low areas between ridges, which are predominantly black. False corrosion and encrustation is present on the modern pin. The pin and spring are modern restorations and have been soldered onto the bow at both ends with a lead or tin solder or both. The bow of the fibula was cast, and the surface decoration was done in the model prior to casting.
