Technical Observations: The patina is a patchwork of green, cupritic red, and black. The body of the brooch appears to have been cast in one piece with the catchplate and the hinge loop on the reverse. The pin is now missing, but the rusty remains that have built up around the hinge loop indicate that it was iron. The surface of the brooch has been extensively mechanically cleaned, carving through the green and cupritic corrosion accretions and making it difficult to determine the exact nature of the original modeling and cold working. The two openings below the beaks of the stylized bird heads were created in the wax model rather than in the metal.
