By art historians named as "Giovanna degli Albizzi Tornabuoni"; again, like in the case of her daughter, the Milanese Duchess Isabella von Aragon, who has been named by the art historians as the merchant's wife Mona Lisa, there is no proof whatsoever. This portrait painting of Ippolita Maria Sforza was created in the year of her death, 1488. This mistake could only have been made, because the art historians have not only no knowledge about the specific symbols (or emblems) of the high dynasties of the Renaissance, but also do not know that (almost) all women of all times like to copy the clothes and the hairstyles of famous members of their gender.
A letter, which Ippolita Maria Sforza wrote to her best friend, Lorenzo il Magnifico de' Medici, in December 1486: "I cannot tell you the pleasure it gave me to see your handwriting and I have found even more pleasure in seeing your nephew [Luigi de' Rossi], as I think he has something of you about him; and God knows how I long to see you, so that I can thank you with my own lips for all you have done for me and mine; for I am sure that I could not be more obliged to anyone than to Your Lordship, though you have been acting for yourself, since you know that our affairs are your affairs. Magnifico Lorenzo mio, I do not know how your wife would like your taking so much care of the soul you wot of, for those who indulge in such devotions observe vigils not written in the calendar. However, to obey you, though without sharing the wickedness, I send you the gloves [of course her gloves!] and some other trifles suited to your devotion. If you want anything else, say so, for I am as glad to do anything to please you as I should be for my own brothers." (in: Lacy Collison-Morley: The early Medici, London 1935, p. 153).
