Montifaud did not shy away from addressing sexual themes in her writing, even in the context of histories of the church. In addition, she had a worldview that scholar Wendelin Guentner characterizes as "profoundly spiritual, though unapologetically pagan." The prevalence of such themes in her writing caused her to be condemned as pornographic or
anti-clerical by the French authorities, leading to censorship of her works and legal charges of indecency. She was required to change the title of her first publication to eliminate the word "
courtesans." She was fined and even imprisoned for four of her works. She was sentenced to eight days in
Saint-Lazare, a women's forced-labor prison, as punishment for "offense to public decency" in her publication
Alosie, or The Loves of Madame de M.T.P. (1876), a re-publication of a work by Pierre-Corneille Blessebois
. She managed to escape to Brussels and was able to convince the authorities to convert the sentence into a stay in a mental hospital, Maison Dubois. The following year she published
Les Vestales de l’Église (
The Vestal Virgins of the Church), which earned her another sentence at Saint-Lazare, this time for three months. She once again persuaded the court to carry out the sentence at Maison Dubois. Throughout these trials, she argued that she was being treated more harshly than her male literary counterparts such as
Charles Baudelaire or
Gustave Flaubert who were charged with the same offense. == Selected works ==
