Technical Observations: The patina is black with spots of red. The surface is well preserved. It is slightly rough, but this could be the original condition.
The simple, flat, outline design, with raised detail lines and a flat, plain reverse, indicate that a durable model was used to make an impression in a clay casting mold. The raised lines could have been cut directly in this mold to add relief detail, and the rough texture of the lines supports this. Molten metal could have been poured into a one- or two-piece mold.
