You’ve probably seen it. Maybe on a book cover for a gothic novel or in a textbook about the Romantic era. A woman lies sprawled across a bed, draped in white, looking more like she’s in a deathly stupor than a peaceful slumber. On her chest sits a hideous, squatting creature—the incubus—looking directly at the viewer with an expression that is both mocking and terrifying. And then there’s that horse. That bug-eyed, ghostly mare peeking through the velvet curtains. The Nightmare Henry Fuseli painted in 1781 remains one of the most unsettling images in Western art history because it doesn’t just show a dream; it shows the visceral weight of terror.
Art was different before this. In the late 18th century, the Royal Academy in London was mostly obsessed with portraits of wealthy people in nice wigs or "History Painting"—noble scenes from Greek myths or the Bible that were supposed to teach you a moral lesson. Then comes Henry Fuseli, a Swiss-born minister turned painter who was basically the dark wizard of the art world. He didn't care about moral lessons. He cared about the subconscious before we even had a word for it. When he exhibited this at the Royal Academy in 1782, people didn't just look at it. They gasped. Some reportedly fainted.
It was a total shock to the system.
Honestly, it’s hard to overstate how much this single canvas changed the trajectory of how we think about the mind.
What’s Actually Happening in The Nightmare?
To understand the painting, you have to look at the folklore Fuseli was tapping into. The "Night-mare" wasn't originally about a bad dream in the way we think of it today. The word "mare" comes from the Old English mara, a term for a spirit or goblin that was believed to sit on the chests of sleepers, suffocating them.
It’s sleep paralysis.
Pure and simple.
If you’ve ever woken up unable to move, feeling a crushing weight on your ribs while sensing a "presence" in the room, you’ve experienced exactly what Fuseli captured. He took a physiological horror and turned it into a theatrical masterpiece. The woman is illuminated in a way that feels almost supernatural, her body contorted in a "v" shape that suggests total vulnerability. She’s not just sleeping; she’s being consumed by the experience.

The creature on her chest is the star of the show, though. It’s an incubus. In medieval lore, these were demons that had sex with sleeping women. Fuseli’s version is ugly, hairy, and undeniably heavy. It’s the physical manifestation of the "pressure" felt during a nightmare.
Then we have the horse. Why is there a horse? It’s a bit of a pun, really. "Night-mare." Get it? But it’s also more than a bad joke. The horse’s eyes are white, glowing, and sightless. It represents the irrationality of the dream world. It’s the wild, untamable force of the dark.
The Anna Landolt Connection: A Bitter Love Story
Here is the part most people miss. This wasn't just a random spooky painting. It was personal. It was petty. It was a 18th-century "diss track."
Years before he painted The Nightmare Henry Fuseli fell madly in love with a woman named Anna Landolt. She was the niece of his friend Johann Kaspar Lavater. Fuseli was obsessed. He wrote letters about her that would honestly get him blocked on social media today—intense, erotic, and borderline delusional fantasies. He wanted to marry her. Her father, however, was not a fan. He blocked the marriage, and Anna eventually married a boring, stable family friend.
Fuseli was devastated and angry.
Some art historians, like H.W. Janson, have pointed out that if you look at the back of the original canvas, there’s an unfinished portrait of a woman who looks remarkably like Anna Landolt. The theory is that the woman in The Nightmare is Anna. Fuseli was essentially painting his lost love being tormented by a demon—a demon that some suggest represents Fuseli himself, taking a dark, voyeuristic revenge on the woman who rejected him.
It’s messy. It’s complicated. It’s very human.

Why It Broke the Art World
Before this, "sublime" art was usually about big mountains or scary storms—nature being huge and scary. Fuseli turned the "sublime" inward. He suggested that the scariest thing wasn't a thunderstorm; it was your own brain when the lights went out.
The painting was so popular that it was engraved and sold as prints everywhere. This is how it became a pop culture phenomenon. It reached people who never would have stepped foot in an art gallery. Political cartoonists started using the imagery to mock politicians. If a minister was "suffocating" the economy, they’d draw him as the incubus sitting on the chest of "Britannia."
It was the first viral meme.
Its Influence on Literature and Psychology
You can't talk about Gothic horror without mentioning this painting. Mary Shelley, the author of Frankenstein, knew Fuseli. Her mother, Mary Wollstonecraft, had actually been in love with him (the man had a complicated love life, clearly). When Shelley writes the scene where Victor Frankenstein finds his bride Elizabeth murdered on their wedding night, the description of her body draped across the bed is almost a direct copy of Fuseli’s composition.
And then there’s Sigmund Freud.
Freud supposedly had a print of The Nightmare hanging in his waiting room in Vienna. He was obsessed with it. For Freud, this was the ultimate depiction of repressed sexual desire and the "uncanny." He saw the horse and the demon as symbols of the id—the dark, primal parts of ourselves that we try to hide during the day but that come out to play at night.
The Technical Brilliance (Or Lack Thereof?)
If you ask a technical art critic, they might tell you Fuseli wasn't the "best" painter in terms of anatomy. The woman's neck looks a bit long. Her arms are positioned in a way that might actually be impossible. But that’s missing the point.

Fuseli wasn't trying to be a camera. He was trying to be a director.
He used a technique called chiaroscuro—the dramatic contrast between light and dark—to make the scene pop. The background is a murky, reddish-brown void. This makes the pale white of the woman’s gown and the glowing eyes of the mare feel like they are jumping out of the frame. It’s a theatrical trick. It creates a sense of claustrophobia. You feel trapped in that room with her.
Is it really "The Nightmare"?
Interestingly, Fuseli never actually titled it The Nightmare in a formal sense when he first conceived it, but the name stuck immediately because it was so obvious. He eventually painted several versions of it. The most famous one (the 1781 version) lives at the Detroit Institute of Arts. Another version, painted in 1790-91, hangs in the Goethe-Museum in Frankfurt.
The later versions are arguably even more erotic and intense. Fuseli knew he had a hit on his hands, and he wasn't afraid to lean into the shock value. He was sort of the Stephen King of his era—he knew exactly which buttons to push to make the public uncomfortable and intrigued at the same time.
How to View the Painting Today
If you get a chance to see it in person, don't just look at the monster. Look at the textures. Look at the way the light hits the fabric. It’s a masterclass in mood.
When we look at The Nightmare Henry Fuseli today, we aren't just looking at an old painting. We’re looking at the birth of the horror genre. We’re looking at the first time an artist dared to say that our internal lives are just as messy, scary, and weird as the world outside.
It’s a reminder that even in the "Age of Reason," the monsters never really went away. They just moved into our heads.
Actionable Insights for Art Lovers
- Visit the Original: If you're in the Midwest, the 1781 masterpiece is at the Detroit Institute of Arts. It's much smaller than you’d expect, which actually makes it feel more intimate and creepy.
- Compare the Versions: Look up the 1790 version side-by-side with the 1781 original. Notice how the incubus changes and how the horse becomes even more prominent. It shows how Fuseli refined his "scare" over a decade.
- Explore the Gothic Context: To really "get" the vibe, read a few chapters of Horace Walpole’s The Castle of Otranto or Mary Shelley’s Frankenstein. The painting is the visual language of those books.
- Look for the "Fuseli Scheme": Notice how modern horror movie posters use the same lighting—one bright central figure surrounded by absolute, crushing darkness. That’s the "Fuseli effect" in action.
- Study Sleep Paralysis: If you're interested in the science, research the "Hag" or "Old Hag" phenomenon. It provides a fascinating biological context for why so many different cultures have a version of the creature in this painting.
The Nightmare Henry Fuseli created isn't just a relic of the 1700s; it’s a mirror. It reflects the parts of ourselves we only see when our eyes are closed. Whether it’s a manifestation of lost love, a pun on folklore, or a study in repressed trauma, it remains the ultimate "jump scare" of the art world.
To understand modern horror, you have to understand this bed, this woman, and that terrifying horse. Once you see it, you can't really unsee it. And that, honestly, was exactly what Fuseli wanted.
