Imagery, in a literary text, occurs when an author uses an object that is not really there, in order to create a comparison between one that is, usually evoking a more meaningful visual experience for the reader. It also creates a collection of images. The elements in a literary work used to evoke mental images, not only of the visual sense, but also of sensation (touch, taste, smell, sound, orientation) and emotion. An example of this is found in The Book of Margery Kempe: "The sacrament shook and flickered to and fro as a dove flickers with her wings." Imagery was also used commonly by William Shakespeare, from which he could create sensational feel for the reader. A great example of this is in Macbeth, where he uses imagery to show the emotion of Macbeth himself in his final living moments. Imagery also occurs when the author of a certain exerpt is describing something in such detail to help envision the object or person(s).
