'Mise en abyme (also mise en abîme) has several meanings in the realm of the creative arts and literary theory. The term is originally from the French and means, "placing into infinity" or "placing into the abyss". The commonplace usage of this phrase is describing the visual experience of standing between two mirrors, seeing an infinite reproduction of one's image.'
