In modern times, the term "Domnei" is especially known for its usage in the title and plot of Domnei: A Comedy of Woman-Worship (1913), a fantasy novel by James Branch Cabell, which is set in the imaginary French province of Poictesme during the second half of the thirteenth century.
A region called Gâtinais is a neighbour of the fictional land of Poictesme in James Branch Cabell's Biography of the Life of Manuel.
