Carolus-Duran was a fashionable portraitist specially noted for his ability to paint fabrics and lace. In the novel, he eventually paints a portrait of my society hostess, Cornelia Renick, and takes Jeanette on as a pupil. Before I reached that part of the story, though, this Portrait supplied me with a dress for Cornelia to wear when Jeanette first meets her at a dinner party given by the Renicks to welcome the Murers to Paris.
