I'm seeking a single English word I recently learned (and then promptly forgot!) --a specialized technical term meaning fictional writing focused around the depiction of another work of art (e.g. a painting, piece of music or a play).
Example: Walter Moers' ______ book The Labyrinth of Dreaming Books really strongly evoked the sensation of sitting in a theater, watching a play.
This is a real English word, but not one in common general use --you would expect it in an academic context, or to be used by a professional critic.
