This rare quadrangular bronze fragment originally formed a central element of a chest or back protection, integrated into plate armor or fixed on a thick leather backing. The main decoration is structured around broad flat bands crossed diagonally, creating a powerful diamond pattern. This geometric network defines recessed compartments, adorned with fine parallel and concentric incised lines that evoke stylized chevron motifs. The border is defined by a double straight moulding encasing a frieze of highly regular repetitive motifs. The presence of tangs or peripheral partial perforations suggests the original assembly system by rivets or leather laces.

This rigid, symmetrical ornamental vocabulary is characteristic of the military bronze production of the Han-Vietnamese sphere, where the Dong Son technological tradition merges with the organization and graphic style of the armies of the Han Empire.

The piece attests to mastery in bronze casting. The thickness and density of the metal confirm its real defensive function rather than purely ornamental or funerary.

Surface mineralization, particularly visible on the inner face and edges, developed during prolonged burial in a damp and acidic environment, typical of archaeological contexts in the Red River Delta. Metal alteration preserved the clarity of the incised decor while adding a rich and authentic texture to the object. Fragmentary. Pronounced excavation oxidation with substantial copper concretions, including green malachite, azurite and cuprite. The patina alternates between soft gray-green tones and darker brown areas. Heavily cleaned by the previous owner.
