Technical Observations: The patina is rough green with some black and areas of bright preserved bright metal in the interior. The breastplate fragment was probably formed into a sheet by cold working. However, only subtle indications of hammer marks are visible in the x-radiograph. The rough, corroded texture of the surface makes it difficult to be sure, but the incised and relief lines appear to have been formed by cold working both sides of the surface. Neither the surface nor the x-radiograph reveals evidence of individual hammered tool marks in the linear decorations or palmette patterns. It is possible these lines were created by drawing a smooth-pointed tool along the surface, perhaps with the aid of a guide. The smaller palmette pattern would likely have been produced with a single punch, but the surface is too damaged to see evidence of this.
