The technical name for this piece of horse armor is a chanfron, which was used to protect a horse’s head on the battlefield. This piece was unearthed in the primary chamber of outer coffin tomb No.65 in Sarari, Gyeongju. Specialized harnesses such as this required a high standard of manufacturing technology that would have been available to only a very select group of people, so this piece represents an important resource for the study of the society and culture of that time.
