It is an artistic resource by which the author introduces in his work a reference to himself as such, outside the narrative and the image he represents; in some cases it may be a reference to the story of the same author, or the actor who plays it if it is a play, film or television. The idea is to break with the story remembering that it is a fiction by putting it in the context of its physical reality, by showing that it is a creation of an author, who is played by actors, or until these actors have a real and public life. See mise en abîme , Droste effect , mise en abyme .
