We do not know, what the 26th century will look like. Many things can happen, many things and information can get lost. What if nobody in that century had ever heard about our famous English Queen Elizabeth II and had no knowledge at all what she looked like? But there would still be one portrait of her (Fig. 1) that survived to this time. Will Elizabeth II suffer the same fate as the Milanese Duchess Isabella of Aragon (1470-1524) (Fig. 2), the most famous woman of the Italian Renaissance, and be degraded to a merchant's wife? In contrast to the famous portrait of Isabella of Aragon, still called "Mona Lisa", there are no symbols of her dynasty attributed to her photo so that she can easily be identified.
