Short answer: At the end of The Lighthouse, Thomas Howard — the younger keeper, who has been living under a stolen name — finally reaches the forbidden light at the top of the lighthouse, is overwhelmed by it, and falls down the stairs. He ends up naked on the rocks, still alive, as gulls peck at his exposed organs. It is a direct echo of the myth of Prometheus, punished for stealing fire from the gods.
Almost everything else — what was real, what was hallucinated, and what was inside the light — is deliberately left open by director Robert Eggers. Shot in stark black and white in a cramped, nearly square frame, the film wants you to feel the same confinement as its two characters.
Spoiler Plot Recap: Two Keepers, One Island
Set in the 1890s, two keepers begin a four-week shift on a remote, storm-battered island. Thomas Wake, the older keeper, guards the lantern room jealously and gives the younger man, Ephraim Winslow, all the grinding labour: hauling kerosene, emptying chamber pots, maintaining machinery.
As the relief boat fails to arrive, the men drink, argue, and unravel. Winslow is tormented by a one-eyed gull, despite Wake’s warning that gulls carry dead sailors’ souls and killing one brings bad luck. He hallucinates mermaids and sea monsters. Then he confesses: his real name is Thomas Howard, taken from a fellow lumber worker who died in an accident Howard feels responsible for.
Wake keeps a damning logbook of Howard’s supposed misdeeds and refuses ever to let him near the light.
The Ending, Scene by Scene
The final fight. After discovering Wake’s logbook, Howard confronts him. During the violent struggle he hallucinates Wake as a tentacled sea-god figure, with visions of the mermaid and the dead Winslow crowding in. The film never says which of this is real; the outcome is certain — Howard beats Wake into submission.
Buried alive. Howard drags Wake to a hole at the base of the lighthouse and begins burying him alive. Before losing consciousness, Wake warns of a Promethean punishment awaiting anyone who looks into the lantern. Howard takes the keys to the lantern room anyway. The warning, of course, is also a dare.
Wake’s death. Wake revives and attacks Howard again. Howard kills him and is finally alone. Nothing now stands between him and the light.
The lantern room. Howard climbs the spiral staircase and opens the great Fresnel lens. Light floods out. He reaches into it, screaming and laughing in what looks like ecstasy and agony at once, his face contorting in the glare. The audience never sees what is inside the light. Then he loses his footing and tumbles down the stairs.
The final shot. Howard lies naked on the rocks, one eye damaged, barely alive, as gulls peck at his exposed organs. The lighthouse is nowhere in the frame. The film ends on that image and holds it.
Prometheus and Proteus: The Myths Behind the Ending
Eggers has confirmed the film’s two guiding myths. Wake is modelled on Proteus, the shape-shifting Old Man of the Sea — a keeper of secrets who must be wrestled into revealing the truth, which is why Howard hallucinates him as a tentacled sea god.
Howard is Prometheus, the Titan who stole fire from the gods and was punished by being chained to a rock while an eagle ate his liver daily. Howard steals the light — the film’s stand-in for divine fire — and his punishment is staged almost literally: pinned to the rocks, his insides eaten by birds.
Competing Interpretations
| Interpretation | What it says | What supports it |
|---|---|---|
| The myth reading | Howard is Prometheus; Wake is Proteus; the ending is a retold myth | Eggers’s own comments, the gull punishment, Wake’s sea-god hallucination |
| The madness reading | Everything supernatural is hallucination; isolation and guilt broke Howard’s mind | The unreliable perspective, the drinking, the failed relief boat, the guilt over Winslow |
| The purgatory reading | Howard is already dead or dying, reliving his punishment in a loop | The final shot excludes the lighthouse; the film’s circular, dreamlike structure |
| The Icarus reading | Howard flew too close to forbidden knowledge and fell, like Icarus to the sun | The literal fall down the stairs after reaching for the light |
These readings overlap. The myth reading explains the ending’s shape; the madness reading explains why we cannot trust what we see; the purgatory reading explains why the last shot feels both final and endless.
Frequently Asked Questions
What did Howard see inside the light? We never find out. The camera stays on Howard’s face. Eggers has suggested the point is not a hidden object but the act itself: reaching for forbidden knowledge and being destroyed by it.
Is Howard dead in the final shot? He appears alive but mortally wounded as the gulls feed on him. The film does not confirm his death — fitting, since Prometheus’s punishment was eternal, repeated daily.
Was the mermaid real? Almost certainly not literally. She appears as part of Howard’s hallucinations, fed by isolation, alcohol, guilt, and desire — though the film never labels any vision definitively false.
Did Howard murder the real Ephraim Winslow? The film keeps this ambiguous. Howard says Winslow died in a logging accident; whether he caused it, failed to prevent it, or simply watched it happen is left unclear.
Why does the lighthouse vanish from the final shot? It may mean Howard crawled away after his fall, or that the lighthouse was a vision all along. Either way, he is left with only rocks, sea, and birds.
