Technical Observations: The patina is green with areas of rust color. The object was probably formed by cold working the bronze into a thin sheet. X-radiography appears to show hammer marks. Lines neatly formed on the front correspond to rougher striations on the back that were made to reinforce the repoussé effect on the front. The letters of the inscription were made using a 9-mm punch tool.
