Technical Observations: The patina is green with light green spots and brown burial accretions. The surface is well preserved. Chip losses show that the corrosion layer is at least 1 mm deep in some areas. A 1-cm corner of the catchplate is broken off and lost.
The bow section of the fibula was cast, probably from a model made directly in wax. The pin, coil spring, and catchplate were part of this casting but were cold worked into their shapes. An elongated chisel point and hammer were used to create the small facets around the incised lobes. The flat sections between the lobes and the pin section are decorated with tremolo, a fine zigzag pattern made by rocking a curved chisel point back and forth over the surface.
