Translucent pale blue and opaque mid blue. Square or rectangular, flat plaque; straight upper edge in mid blue, with projecting rough edge and grozed back in pale blue. Decoration in high relief: parts of two figures: at left, raised (proper left ?) arm bent upwards at elbow; at center, naked male figure leaning forward to left but with his head truned back in three-quarter view to right and proper left arm behind a large, unidentified object; behind arm of first figure in low relief a trident; below and in front of central figure, foliate sprays. Fragment with weathered broken edges, but one area with clean break at bottom left; small part of top edge remaining; dulling, pitting, whitish weathering, and faint iridescence.
The plaque is not a true cameo, since the translucent blue background is completely covered with a thin layer of opaque light-blue glass. The scene, which involves a man and at least one other person, cannot now be identified.
