Clear glass; blown and diamond-point engraved. Shallow body with ground pontil mark. On exterior a broad frieze in elaborate diamond-point engraving representing the "Roman Invasion", including fighting scenes between Romans and "Britons". An inscription below the rim reads: "THE ROMAN TROOPS WERE TOO HEAVILY WEIGHTED WITH ARMOUR TO DEAL WITH SUCH AN ENEMY AND COULD NOT PURSUE THEM WHEN THEY RETREATED. THE TERROR INSPIRED BY THE HORSES AND THE NOISE OF THE WHEELS WAS SUFFICIENT TO THROW THEIR OPPONENTS INTO DISORDER". Around the center there is the following inscription: "THE BRITONS WOULD GENERALLY GIVE GROUND ON PURPOSE, AND AFTER DRAWING THEM SOME DISTANCE, WOULD JUMP FROM THE CHARIOTS AND FIGHT ON FOOT, GIVING THE MOBILITY OF CAVALRY AND STRENGTH OF THE INFANTRY".
