Technical Observations: The patina is dark green. The remains of an iron attachment are visible at the terminal of the shank. Fine striations on the front surfaces are the result of abrasive finishing of the bronze casting.
The object is a solid lost-wax cast. Five separately formed sections of wax—the outer frame, horizontal band, upper frieze, lower frieze, and shank—were joined and then incised with sharp tools to complete the wax model. All but the shank were cut from sheets of wax, and the two frieze sections may have been initially formed by pressing a sheet of wax into an open mold. Marks from manipulation of the wax are present over much of the reverse. The joining of the separate sections in slightly different planes allowed for higher relief in the figural elements.
