Engraving of a Roman or Greek seal with an image of a Nereid, clad in robes, seated on the back of a horse-fish chimera. Above and below the representation of the seal are printed "Tab. XXXI" and "NEREIS" (a patrynomic applied to the daughters of Nereus, the Nereides). This is surrounded by a large, ornate border printed from a separate block with red ink, or with ink that has discolored to red. At the base of this border are the artist attributions.
