Technical Observations: The patina is a mottled light green, with olive brown and dark gray spots in the better-preserved areas of the surface and orange in the corrosion pits.
The mitra was formed from a sheet of bronze. It is not clear from the available evidence how this sheet was produced. The rounded top edge of the mitra was formed by bending it outward, probably over a wire, and the edges of the rounded section were rolled inward over a finer wire, much like the other mitrai in Harvard’s collection (1). The decorative ribs were created by repeatedly pressing or drawing a smooth pointed tool over the back surface. The ribs were then enhanced on the front surface with carefully incised lines, some with a very fine serrated-edged tool. X-radiography shows that the metal sheet is of relatively even thickness overall except for the ribs, which are much thinner. Of the three holes that held rings in the top edge, only the central hole is preserved; the holes were cut through the decorative lines after they were created.
Most of the metal surface on the front of the mitra was originally highly polished, although restoration may account for some additional smoothing. The back surface would also have been polished, but it is almost entirely obscured by corrosion and burial accretions. The inscription that was first scratched on to the front of the mitra was enhanced with short straight lines (c. 0. 2 mm long) that were struck in sequence over the incisions.
