A painted or carved triptych typically has three hinged panels, and the two outer panels can be folded in towards the central one. A literary or musical triptych generally consists of three closely related or contrasting themes or parts. Triptych derives from the Greek triptychos ("having three folds"), formed by combining tri- ("three") and ptychē ("fold" or "layer"). Although triptych originally described a specific type of Roman writing tablet that had three hinged sections, it is not surprising that the idea was generalized first to a type of painting, and then to anything composed of three parts.
