In Medias Res - GCSE English Literature Definition

Key Takeaways

• In medias res is Latin for "into the middle of things" and describes a narrative technique where a story begins mid-action

• The technique was first identified by the Roman poet Horace in his Ars Poetica (c. 19 BC), praising Homer's approach in The Iliad

• The opposite approach is called ab ovo ("from the egg"), where the story starts at the very beginning

• Writers use in medias res to hook readers immediately by dropping them into a moment of tension or conflict

• In medias res appears across literature, film, and television, from The Odyssey to Breaking Bad

What Does In Medias Res Mean?

In medias res is a Latin phrase that translates literally as "into the middle of things." It's a narrative technique where a story opens at a dramatic or significant moment, rather than starting from the chronological beginning. The reader or audience arrives mid-action, mid-conversation or mid-crisis, and the writer fills in the backstory later.

You'll sometimes see the phrase written as "in media res" (without the 's'). This is technically incorrect. The correct Latin form uses the accusative plural: "in medias res." Both spellings appear online, but stick with "in medias res" in your own writing.

Here's an example in a sentence: "Dennis Kelly’s play DNA uses in medias res by opening with Jan and Mark discussing an event that has already occurred."

In Medias Res vs Ab Ovo

These two terms describe opposite ways to start a narrative. In medias res drops the reader into the middle of events. Ab ovo (Latin for "from the egg") starts from the very beginning, following events in strict chronological order.

Neither approach is better. The choice depends on the effect the writer wants to create. A detective novel might open at a crime scene (in medias res), while a family saga might begin with a birth (ab ovo).

Origins and History of In Medias Res

The Roman poet Horace coined the term in his Ars Poetica (c. 19 BC). He praised Homer for not beginning The Iliad with the origins of the Trojan War, but instead plunging readers into the conflict. Horace contrasted this with poets who tried to tell everything from the start, arguing that Homer's approach was more gripping.

Homer's The Odyssey does the same thing. The poem opens with Odysseus trapped on Calypso's island, years into his journey home. His earlier adventures (the Cyclops, the Sirens, Circe) are told later as flashbacks when Odysseus recounts them at a feast.

Horace's advice stuck. Centuries of writers followed it, from Virgil's Aenid to Dante's Divine Comedy. The technique became a defining feature of epic poetry and eventually spread to novels, plays, film, and television.

Examples of In Medias Res in Literature and Film

These examples share a pattern. Each one opens at a moment designed to provoke a single question: how did we get here? That question keeps the audience engaged through the backstory that follows.

“Students often overlook structural analysis in favour of analysing language, but this means they miss important aspects of a literary work. When a writer begins in medias res, they set up important themes. For example, Shakespeare’s Hamlet opens with castle guards questioning whether they have seen a ghost. This introduces key themes of doubt and uncertainty.”

Effect of In Medias Res on the Reader

The technique works because it exploits curiosity. When readers find themselves immediately in the middle of a crisis, they don't have the context to understand what's happening. That gap between what they see and what they know creates confusion and builds tension.

Three specific effects stand out:

• Immediate engagement. There's no slow build-up. The reader is inside the action from the first line, which hooks the reader or audience straight away.

• Suspense through information gaps. The reader knows something significant has happened but doesn't yet know why. This reverses the dynamic of dramatic irony and keeps the reader actively piecing together the narrative.

• Control over revelation. The writer decides exactly when and how to reveal backstory. This means they can reveal information for maximum impact, drip-feeding context through flashbacks, dialogue, or the narrator's memory.

When analysing in medias res in a text, focus on what the writer has withheld and why. Ask yourself: why is certain information not revealed at the start? That question will push your analysis beyond simply identifying the technique.

“The opening of a text is always revealing. I suggest students lean into any confusion they experience when they start reading either the first chapter of a novel or the first scene in a play. This confusion is often created on purpose to recreate the characters’ own sense of turbulence or to thrust us into their chaotic world!”

How to Use In Medias Res in Your Own Writing

Pick a moment of conflict, decision, or tension from your story. This isn’t the very peak of the action (that's your climax), but it’s a moment charged enough to raise questions. It could be a confrontation, a discovery, or an escape already underway.

Three practical tips:

1. Give just enough context. Your reader needs to understand who is present and roughly what's at stake, even if they don't know the full picture. One or two concrete details, such as a clear setting and an important relationship, anchor the scene without over-explaining.

2. Plan how you'll deliver backstory. You'll need to weave in earlier events after your opening. You can do this through a character's memory, a conversation that references the past, or a shift to an earlier time period. Avoid dumping three paragraphs of explanation immediately after your opening scene, though.

3. Don't confuse the reader for too long. Disorientation can be effective for a paragraph or two. Beyond that, it becomes frustrating. The goal is "I need to know more," not "I have no idea where we are or what's happening."

A common mistake is treating in medias res as a gimmick. If your opening scene doesn't connect meaningfully to the rest of the story, the technique falls flat. The best in medias res openings feel inevitable once you've read the whole piece.

If you're studying structural techniques for your English exams, Save My Exams has revision notes on Structure Analysis that cover how to identify and analyse techniques like in medias res in unseen texts. The notes are written by experienced teachers and examiners, with model answers showing how to write about structure effectively.

Frequently Asked Questions

Is it "in media res" or "in medias res"?

The correct form is "in medias res" with the 's'. This follows Latin grammar, where "medias" is the accusative plural form of "medius" (middle) and "res" is the accusative plural of "res" (thing or matter). "In media res" is a common misspelling that drops the plural agreement, but it's widely understood even if technically wrong.

What is the difference between in medias res and a flashback?

In medias res is a structural choice about where a story begins. A flashback is a technique used within a story to show earlier events. The two often work together: a story that opens in medias res frequently uses flashbacks to fill in the backstory. But a flashback can appear in any story, regardless of where it starts.

Why did Homer use in medias res in The Odyssey?

Homer opens The Odyssey during Odysseus's journey, skipping his departure from Troy and his early encounters with monsters. This creates immediate intrigue (where is Odysseus? will he return?) and allows Homer to reveal the most dramatic adventures later. The oral tradition also favoured jumping to the most compelling part of a well-known tale.

Can in medias res be used in non-fiction writing?

Yes. Journalists and essayists regularly open with a vivid scene before pulling back to explain the wider context. A feature article might begin in an operating theatre or a courtroom, then shift to the background that led to that moment. The principle is the same: start with something gripping, then fill in the "how we got here."

What is the opposite of in medias res?

The opposite is ab ovo, a Latin phrase meaning "from the egg." Ab ovo narratives begin at the very start of events and follow a strict chronological order. Horace used the term in his Ars Poetica to describe the kind of storytelling he felt was less effective than Homer's in medias res approach.
