Andre Gide adopts the heraldic term mise en abyme, or a shield shown in the center of a shield, to describe a work within a work, like The Mousetrap in Hamlet, but Gide ultimately rejects such examples because The Mousetrap does not represent Hamlet as a whole, but only the actions of the characters within the play (as I discuss in Into the Abyss: The Mise en Abyme, the Art Work Within the Art Work). In turn Lucien Dällenbach challenges Gide’s metaphor of a shield within a shield, the heraldic device mise en abyme because the smaller shield does not represent the larger shield, but presents a new device. Dällenbach prefers the metaphor of a mirror, a metaphor Gide also use: “although Gide initially rejects the image of the mirror in favor of the one from heraldry, he later reverses this decision and enjoins us, if not purely and simply to substitute the idea of mirror reflection for that of the mise en abyme, at least to see the two terms as equivalent” (Dällenbach 34).
A book within a book, a play inside a play, a picture in a picture, these are examples of mise en abyme, a literary term the French writer André Gide borrowed from heraldry. Pronounced “meez en a-beem,” it literally means “placed in the abyss,” or, more simply, “placed in the middle,” and it was used to describe a shield in the middle of a shield, as in this coat of arms of the United Kingdom from 1816-1837.

You’ll notice that the shield inside the shield has another shield inside of it. You can imagine yet another inside that one and so on and so on, forever and ever, so I like to think of “mise en abyme” as “into the abyss.” The eye travels down the rabbit hole to infinity, as in this photo of a “Lost Wormhole” from Illuminaughty Boutique’s post “38 Mise en Abyme GIFs that Will Make Your Brain Bleed… OR WORSE.”
