Ornate rectangular plaque with symmetrical relief

The plaque is rectangular with a smooth surface. It features a symmetrical, multi-layered design carved in relief. The design incorporates a snake entwined with a flower, a leaf motif, and a stylized bird's head. Prominent sculpted wings, detailed with feathering, are positioned in the upper right and lower left corners. The entire design, in shades of gray, suggests a stone or stone-like material, possibly intended for architectural ornamentation.
