In the 19th century, a romanticised version of her early life was popularised by the play King René's Daughter by Henrik Hertz, in which she is portrayed as a beautiful blind princess living in an isolated garden paradise.

[1] The marriage was a dynastic alliance, arranged to end the dispute which existed between René of Anjou and Frederick's father, Antoine of Vaudémont, regarding the succession to the Duchy of Lorraine.

In 1473, on the death of her nephew Nicolas, she inherited the Duchy of Lorraine, but passed it immediately to her eldest son René II.

The portrayal of Yolande as a saintly dreaming beauty (regularly placed in an entranced sleep by the physician) was immensely popular.

In 1913 a silent film of Hertz's play was made by the Thanhouser Company, starring Maude Fealy as Yolande.

The evidence for this claim was derived from the Dossiers Secrets d'Henri Lobineau, forged documents created in 1967.
