"Then I said to her: “My lady, these examples show that long ago, the wise were honored more than they are now and the sciences were held in greater esteem. But regarding your words about women who are expert in the art of painting, I know a woman right now by the name of Anastasia who is so talented and skilled in painting decorative borders on manuscripts and landscape backgrounds that one cannot find an artisan to equal her in the whole city of Paris, where the best in the world are found.
She so excels at painting flower motifs in the most exquisite detail and is so highly esteemed that she is entrusted with the richest and most valuable manuscripts. I know this from my own experience, because she has done work for me that is considered exceptional among the decorations created by other great artisans."
