In medias res — Latin for "into the middle of things"
— names a narrative technique that's older than the novel and somehow
still feels modern. The phrase comes from Horace's Ars Poetica,
where it describes Homer's habit of starting his epics not at the
beginning of the story but mid-action.
The technique
An in medias res opening drops the reader into the middle of
an ongoing action with no exposition. The earlier events — how we got
here, who the characters are, why any of this matters — are filled in
later through dialogue, flashback, or memory.
The opposite is ab ovo, "from the egg" — starting at the
chronological beginning and proceeding in order. Most fairy tales work
ab ovo. Most thrillers don't.
Why writers use it
It produces immediate stakes. The reader is in a
situation that already matters before they know why. Curiosity does
the work that exposition would otherwise have to do.
It compresses time. A long, slow setup can be
delivered in flashback after the reader is already invested,
avoiding the deadly opening chapter of background.
It frames the story thematically. The "middle"
the writer chooses to start in is rarely random — it usually
contains the story's central image or question.
Canonical examples
The Iliad begins in the ninth year of the Trojan
War, with Achilles already in his tent refusing to fight.
The Odyssey opens with Odysseus stuck on Calypso's
island, ten years into his journey home.
The Aeneid begins with Aeneas already at sea, the
fall of Troy delivered later as a long flashback to Dido.
Paradise Lost opens with Satan already in Hell —
the rebellion in Heaven is recounted in later books.
Beloved by Toni Morrison opens at 124, the haunted
house, with no explanation of who Sethe is or what she did. The
novel pieces itself back together slowly.
In medias res vs. flashback
The two often get confused. A flashback is a single backward jump
from the present action. In medias res describes the entire
structural choice — the story begins in the middle. A flashback
is a tool you can use inside any structure; in medias res is a structure
in itself.
Modern variants
The cold open. TV's version of in medias res: a
scene of intense action plays before the credits, often the climax
itself; the rest of the episode catches up to it.
The framed prologue. A character recounts events
from after they happened — the whole story is delivered as
retrospect, with the "now" of the telling as the entry point.
The unraveling murder mystery. The body is in the
first chapter. Everything before the murder must be reconstructed.
How to read it
When a critic identifies an in medias res opening, the question to
ask is: why this particular middle? The point where the writer
drops you in is usually the thematic core. Notice what you don't know;
the writer has chosen that ignorance deliberately. The slow revealing
of backstory is not a delay — it is the form the story is taking.
