Her literary work consists of the Heptameron, of poems entitled Les Marguerites de la marguerite des princesses, and of Letters.
The Heptameron, constructed, as its name indicates, on the lines of the Decameron of Boccaccio, consists of seventy-two short stories told to each other by a company of ladies and gentlemen who are stopped in the journey homewards from Cauterets by the swelling of a river.
His earliest gallantries are described by his sister in the 25th and 42nd stories of the Heptameron.
They belong to that species of literature of which Boccaccio's Decameron and the queen of Navarre's Heptameron are, perhaps, the best known examples.
