These literary devices are all ways of displacing the idea of temporal linearity in fiction. In other words: Authors don’t always want readers to assume that in stories time moves forward in a straight/simplistic way, or that everything ties up nicely.
A literary device in which an author drops subtle hints about plot developments to come later in the story.
Compare with ‘telegraphing’, which is basically foreshadowing done in an overly heavy-handed way. In this case, the readers are able to predict what is about to happen, even though the author doesn’t want them to.
We find instances of foreshadowing in literature where we would not suspect it in real life, because nothing in a story lacks a purpose, or it wouldn’t be there. (See Chekov’s Gun.) Events in real life cannot be foreshadowed. This makes foreshadowing a specifically literary construction.
Foreshadowing is visible only to the reader, not the characters.
In picture books, foreshadowing can happen in the illustrations. For example, the drawing of the Wild Thing at the bottom of the stairs in Where The Wild Things Are. Upon second reading, the reader knows that Max has been creating these wild things in his imagination.
What is foreshadowing used for?
Foreshadowing gives the feeling that everything in a story is ‘tied-together’, and provides a sense of closure and satisfaction at the end of a story or scene. This technique helps avoid the feeling of deus ex machina, which is the feeling that something has suddenly swooped in to save the day (originally God, and in children’s literature, notoriously, an adult).
Foreshadowing provides the re-reader with extra insight.
Foreshadowing can add dramatic tension by building anticipation about future events. It can also help build a creepy/suspenseful atmosphere.
When added up, the details of foreshadowing can help the reader with verisimilitude, which is ironic, since foreshadowing doesn’t really happen in real life.
What is backshadowing?
Backshadowing is the technique of inserting commentary into the present narrative that refers to earlier narrative events. For example, a child living in present-day Germany discovers that she is a descendent of a war criminal. In order for such a story to make sense, the reader has to know something about Germany and the world wars.
Backshadowing is visible to readers as well as to characters — everyone knows what happened, and the story rests upon this shared schema.
What is backshadowing used for?
Many historians and writers of historical fiction employ backshadowing of real-world historical events because the reader already has a schema. For example, the holocaust might be used as a setting in a romance novel to allow the writer to spend time on the characters and plot. This can be problematic.
In his book Foregone Conclusions: Against Apocalyptic History, author Michael Bernstein criticises authors who use their own and their audience’s knowledge of an apocalyptic event which occurs after the epoch about which they are writing to interpret the actions of their real or imaginary characters. Bernstein’s problem with backshadowing is that it encourages a reader to believe in determinism — that whatever happened in the past lead inevitably to the present we know.
Another use of the term backshadowing: When describing the technique of starting a story with its ending, then shifting back to the beginning with the reader in full knowledge of the outcome but no idea how it all happened. This allows the writer to use a climactic event as a hook, drawing the reader in immediately with the promise that something big and interesting happens. It’s a subcategory of a flashback. In this case, the character is likely to interpret his/her own current (fictional) reality according to whatever happened in the past. In first person narratives where the character is the storyteller, the very act of storytelling becomes the main focus rather than the events themselves — the narrator’s main role is ‘artist’. (See The Role Of Storytellers in Fiction).
Related to ‘backshadowing’ is the bias ‘chronocentrism’, which is the natural human tendency to see one’s own time/era/generation as more special than others.
What is sideshadowing?
A character or narrator posits a series of possible events which never have any consequences in the story.
What is sideshadowing used for?
Sideshadowing draws attention to the possibility that other paths could have been taken. Sideshadowing suggests to a reader that one must grasp what else might have happened in order to fully understand an event. The technique suggests to readers that time is not a line but a shifting set of possibilities. Sideshadowing suggests that nothing can be wrapped up neatly, if at all.
In other words, sideshadowing is used to give a contrasting illumination to the ‘real’ event.
While foreshadowing makes the present and future seem inevitable, sideshadowing emphasises the contingency of the present.
Sideshadowing points outside the narrative, deliberately suggesting to the reader that more things might be going on than what’s expressed in the narrative.
In children’s literature, an example of sideshadowing can be found in Johnny, My Friend:
Let’s turn the clock back, Johnny! […] We’ll take the Alternative where […] you can have a home, Johnny, not just a bit of a smelly monster’s den, and a name, Johnny, you can have an English mum and a Swedish dad and a French sister, and me as a brother, and regular pocket money […]
This is a character visualising a series of alternative events that never happened in the story. (See Maria Nikolajeva’s From Mythic to Linear: Time in children’s literature.)
Lionel Shriver constructs an entire plot around sideshadowing in several of her novels.
Chekov was a fan of sideshadowing in his short stories.
In Russia, Dostoyevsky was no stranger to sideshadowing, either. Might be a Russian thing, because Tolstoy does it too.
Philippa Pearce uses the technique of sideshadowing in Tom’s Midnight Garden.
See also Cheever’s short story called Just One More Time, in which the final scene is an example of sideshadowing, because the reader doesn’t know if it really happened.
