Of the portraits of Cleopatra neither those that are supposed to be authentic nor those that are certainly known to be so, show similarity to the heads on the coins nor to each other. In a marble head in the Capitoline Museum one can perhaps discover in the rounding contour of the face, the regularity of the features and the strong neck, a similarity to our painting.The marble head of a dying woman with a diadem who inclines her head somewhat to the right and opens the mouth in a similar manner described by Bergerus and called Cleopatra, is probably a Niobe, to which also the classically noble lines point. A bronze statuette described by Caylus, which without special reason is considered a Cleopatra, Raoul-Rochette declares to be a Thetis.
