Anna d'Este, Duchess of Guise and Nemours
Isabella d'Este wrote about her, when Anna was still a little girl, the following: "Signora Anna, who played some pieces on the gravicembalo excellently. She also danced several dances in the most perfect time and with most exquisite grace." (in: Christopher Hare: Men and Women of the Italian Reformation, London 1914, p. 107)
