Found Objects

In case you missed the debut of Found Objects last week, the idea of this feature is pretty simple: I'll be posting some sort of visual representation of an object, equation, theory or idea that inspired or made its way into a book, film, song, poem, or painting.

Your job is to name it and tell us where it's found. Today's visual, found below, is from a novel. Can you name the object, the novel and the author?
