“Celestine” is not a single character but a recurring name and persona representing the quintessential bonne à tout faire (maid of all work) in French erotic and satirical fiction. The most famous embodiment appears in Octave Mirbeau’s 1900 novel Le Journal d’une femme de chambre (The Diary of a Chambermaid) , later adapted into films by Jean Renoir (1946) and Luis Buñuel (1964). However, the archetype extends into vaudeville, postcards, and early pornography.
