The bottom of the vase was a cameo glass disc, also in blue and white, showing a head, presumed to be of Paris or Priam based on the Phrygian cap it wears. This roundel clearly does not belong to the vase and has been displayed separately since 1845. It may have been added in antiquity or later, or is the result of a conversion from an original amphora form (paralleled by a similar blue-glass cameo vessel from Pompeii). It was attached to the bottom from at least 1826.
