The Grove Dictionary of Art defines Pastiche as an "image that self-consciously borrows its style, technique, or motifs from other works of art yet is not a direct copy. The result can be sometimes incoherent and at times is deliberately exaggerated and satirical, as in caricature" (Grove Dictionary of Art). Some critics argue that pastiche creates debate regarding social and cultural context. Others argue pastiche lacks innovation and is just a recycling of old ideas. The key to pastiche is one must add something to the original; simply changing the materials used to create the object is not enough.
