Using objects to depict other objects I was wondering if there exists a term that describes the practice of using objects to depict other objects.

To give an example: 

In the painting "The Librarian", Arcimboldo uses books to depict a person.
So the artist uses objects (books) to depict something entirely different (a person).

Thanks!
Pareidolia


  Pareidolia is the tendency to interpret a vague stimulus as something known to the observer, such as seeing shapes in clouds, seeing faces in inanimate objects or abstract patterns, or hearing hidden messages in music.

There are many examples on the internet beyond Arcimboldo, just look for Pareidolia in art.
