The Encounter
Imagine a moonless night. The road you walk is dark, but the sky is clear, and the countless stars in the sky glimmer brightly. You know this road. You have spent most of your life traveling this island. The road you walk now is a narrow stretch, with the sea on one side and a freshwater loch on the other. A familiar path, and almost comforting, though over the last several years, these seaside roads have become eerie.
Recently, locals have begun telling stories of an unnatural creature coming out of the sea, destroying crops, harming livestock, and bringing drought to the island.
You think of these stories as you continue down the narrow road, looking at the barely visible white waves washing onto the shore.
That’s when you first catch sight of it.
Something dark, large, and oddly shaped, making its way out of the water just past where the waves were washing onto the shore.
Your heart begins to race as it continues pressing forward out of the sea. You now see it in far more detail, and your stomach is tingling with fear of this dark creature. You now know, without a doubt, that this is an unholy abomination, and you begin to question what your next move should be.
Under your breath, you ask God to protect you and begin steeling your resolve.
You’re a hard man, seen and done plenty. You can handle yourself fine. Right?
But just as you muster your will, you gain a full view of what this creature is, and your blood runs cold.
This is absolutely not something within your strength to handle.
The monstrosity has the body of a horse, but its legs are like a blend of legs and fins, which it stalks heavily forward on, and its horse’s head splits into a seemingly endless maw of a mouth.
Far from the worst of it, conjoined on the horse’s back, right where a rider would normally be, is the monster’s upper body: the torso of a man, arms reaching and sweeping just over the ground, and its human head, far too large for the body, easily three feet across, rocking side to side on its shoulders as if mocking anyone it approaches with its fiery red eyes and steaming mouth.
The entire thing is skinless. Red tendons and sinew flex and move all of its mass as it continues to press toward you.
That’s when you fully grasp what this is.
The Nuckelavee that people have been telling tales of.
And you know you can’t face it.
You turn and sprint from it, and a few moments later, you hear it following heavily behind you.
You run right along the loch, and you begin to realize that you will not escape this creature.
As you peek over your shoulder, you flinch as its hot breath hits your face, and you pull sideways away from its grasping hands, accidentally plunging a foot into the loch, soaking you.
But the creature cries out and yanks away from you suddenly, toward the other side of the road.
The relief of the moment as you continue to run gives your brain the chance it needs to process the situation, and you remember that this monster is repelled by freshwater. You just witnessed this firsthand.
You need to use the freshwater to separate yourself from the creature immediately.
You switch directions slightly and make a beeline for a freshwater stream coming off the loch up ahead, sprinting with all your strength to reach it.
You can hear the heavy flopping of its fins against the ground as it begins closing in on you again.
Just as it begins to swipe at you again, you dive forward over the stream as it yanks your bonnet from you.
But you are safe.
You hit the ground hard on the other side, rolling with the momentum but stopping, exhausted, on your back.
You look over as the Nuckelavee rears up on its fins and screams in anger, its massive head rolling from side to side.
And you, having spent the entirety of your strength in the chase, fall unconscious as your view of the monster fades to black.
About This Retelling
This is my own creative interpretation of the famous Scottish legend of the Nuckelavee. There are a few changes from the original story, as relayed by Walter Dennison in The Scottish Antiquary in 1890, particularly in how Tammas first responds to the creature and when he remembers its weakness. Still, I feel it captures the spirit of the story well and helps to emphasize for the reader what Tammas's experience must have been like.1
It is a fascinating monster story from the 19th century, with characteristics that distinguish it from other myths and legends of its era. We find some parallels with other stories, but nothing else is quite like it. In this article, I want to explore where the legend came from, what might have inspired it, and how much of it we can actually trace through the historical record.
Walter Traill Dennison
Walter Traill Dennison (1825–1894) was a prominent Orcadian folklorist, historian, poet, and antiquarian.2 Dennison, in his time, served a critical role, even if he himself had not realized it, in preserving a great many pieces of folklore and stories that may have otherwise been lost. One of his notable works was The Orcadian Sketch-Book, a collection of Orcadian lore that he had collected and preserved in writing, though he did so in a medium that combined traditional folklore with his own literary creations, which sometimes makes it difficult to tell what was legend and what was his own creation.3
In 1890, Dennison published his story of the Nuckelavee in The Scottish Antiquary, pages 130–133.1 This was a publication that specialized, as the name suggests, in Scottish history, mythology, and other aspects of local culture.
In the article, Dennison claimed to have known a man who, after some persuasion, reluctantly relayed his close encounter with the Nuckelavee. The encounter occurred very similarly to my version of the story in the introduction to this article, though in the original story, Tammas claimed to have been set on facing the creature head-on, believing that turning his back on an evil spirit was even more dangerous. He also recalled its aversion to freshwater before the creature reached him, unlike my version, where he remembers only after accidentally splashing it. If true, then Tammas was a genuinely hard man, as the vast majority would've bailed at the first sight of the monster, which is the reason for my creative change.1
Sadly, no surname for Tammas was provided, and to my knowledge, no one has established his identity. This means we are unable to explore who he was and what information might come from knowing something about him. This is unfortunate for exploring the legend because he is the only person I have found on record who claimed to have seen this creature firsthand, and all other versions of the encounter I have seen are clearly retellings of Dennison's version of Tammas's story.1
So where does that leave us? With more questions, certainly, but not necessarily a dead end. We have a story recorded by a man well known for preserving oral folklore, though we can't independently verify Tammas's encounter. Dennison himself seemed confident that the Nuckelavee was commonly known.1
So the next step is to track the legend back further. What stories are similar?
Older Monsters of the Northern Isles
One of the striking things about the Nuckelavee story is that its particular name and appearance are difficult to find independently of Dennison’s account, though we can easily draw parallels to other stories, particularly those involving various forms of water spirits and “water horses.”
This is where we find several similar stories, though with some striking differences in their motivations, weaknesses, and appearances.
I have identified three examples that I believe may share the same folkloric lineage, or at least help explain the tradition that the Nuckelavee belongs to.
The Nykur
The Nykur of Nordic folklore is the first creature that we notice draws a particular parallel to the Nuckelavee of Orkney. Like the Nuckelavee, it is described as a horse, though it appears mostly normal aside from its backward-facing hooves, possibly allowing it to lure unsuspecting victims, unlike the Nuckelavee, which is openly terrifying in appearance. It is also a seemingly malicious water spirit, though rather than openly attacking its victims, it attempts to lure people, including children, onto its back before drowning them. The exact motivation for this behavior is unclear, which differs from the Nuckelavee, whose hostility is partly attributed to the kelp-burning industry in Orkney.4,1
The Neagle
Our next creature, which we can see as a potential relative or inspiration for the Nuckelavee, is the Neagle, as described by Reverend John Bryden in 1845 for The New Statistical Account of Scotland, about 45 years before Dennison's recounting of Tammas's Nuckelavee story in Orkney.5
This creature was described as a normal, saddled pony that would haunt the watermills of Shetland. In this creature's case, much like the Nykur we just discussed, it would attempt to lure people onto its back before carrying them out to sea and throwing them into the water, while the creature itself disappeared in a flash of flame.5
In this account, we are also given an explanation of how the creature could be dealt with. The Neagle could be driven away from the mills through the use of burning brands, essentially pieces of flaming wood. Whether the fire actually harmed the creature is unclear, though it was apparently enough to frighten it away.5
This story draws clear parallels with the Nykur, and again we have a malicious horse-like spirit associated with the water. But once again, the creature's appearance is very different from the clearly monstrous Nuckelavee.
One new detail can be seen in the creature's disappearance in a flash of flame. Interestingly, the Nuckelavee was also described as having a single red eye, as red as fire, and breath resembling steam from a boiling kettle. While not exactly the same, the presence of imagery associated with fire and extreme heat in both stories is worth noting.5,1
The Water-Kelpie
The next creature we need to discuss is the Water-Kelpie. This creature was described by Reverend Walter Gregor in his 1881 book Notes on the Folk-Lore of the North-East of Scotland, just nine years before Dennison's account.6
In this version, the creature is described as a black horse which, like our previous examples, would lure people onto its back before carrying them into the water and drowning them. In this case, it also holds a behavioral similarity to the Nuckelavee, as it was known to torment the local inhabitants. Not by blighting crops and afflicting livestock like the Nuckelavee, but by repeatedly visiting homes and terrifying their inhabitants. A slightly different behavior, but an interesting parallel.6,1
What I find particularly interesting about this story is that it presents new information about how these creatures could be defeated. Supposedly, the Water-Kelpie could be captured through the use of a bridle marked with the sign of the cross and subsequently forced into labor. Or, far more interestingly, it could be killed using red-hot iron spits, as described in a story involving a blacksmith who used them to kill the creature after it repeatedly terrorized his family.6
This raises an interesting possibility regarding our previous example. Could the heated iron used against the Water-Kelpie help explain why the Neagle feared burning brands? We can't say whether it was the iron, the heat, or both that killed the Kelpie, and the stories don't establish a shared weakness. Still, it's a comparison worth making.5,6
What the Comparisons Suggest
These examples demonstrate that stories of malicious water spirits taking the form of horses were already part of Northern European folklore by Dennison's time. Some of the accounts we have examined were published before his, while Craigie's collection appeared in 1896 and records traditions that were already in circulation. Though their appearances, behaviors, and weaknesses differ, the similarities between these creatures are difficult to ignore and suggest that they may share a common origin.1,4,5,6
What remains particularly interesting, however, is the Nuckelavee's grotesque appearance. None of these examples describes anything quite like the skinless, half-human creature that Dennison recorded.1,4,5,6
It is possible that the Nuckelavee is simply a variation of these older water-horse legends, perhaps taking on a more centaur-like appearance through the combination of different stories over time. However, I haven't found any earlier accounts that clearly explain where this particular appearance came from.
What we can reasonably determine is that the Nuckelavee shares a number of characteristics with older water-horse legends, but its particularly monstrous appearance remains something of a mystery.
The Historical Connection: Kelp Burning and Disease
One of the interesting details in Dennison's account is the Nuckelavee's hatred of kelp burning, an industry that developed in Orkney around 1720–1721. This involved collecting and burning seaweed to produce materials used in making things like glass and soap. Though profitable, some locals opposed the industry, especially because of the smoke it produced, even though others depended on the income it provided.1,7
Interestingly, between 1739 and 1742, Orkney experienced a series of poor harvests, famine, and livestock deaths. Many of the locals blamed the smoke from kelp burning for these problems, eventually leading to riots in 1742, particularly on the island of Stronsay, where people destroyed equipment and attempted to stop the industry. What I find particularly interesting here is that these are almost exactly the same problems that Dennison would later blame on the Nuckelavee.7,1
Another detail worth mentioning is the disease known as Mortasheen, which Dennison claimed the Nuckelavee spread among the horses of Orkney in retaliation for kelp burning.1 This was actually a recognized name for a horse disease, generally associated with glanders, and appears in an Orkney parish record from 1768, more than a hundred years before Dennison's account.8
So we have a few interesting connections here. Stories of malicious water horses already existed, people in Orkney had experienced real disasters that they blamed on kelp burning, and the horse disease later associated with the Nuckelavee was actually known in the region. None of this proves where the story came from, but I think these events may have helped shape the version Dennison recorded.1,7,8
Conclusion
So in conclusion, what do we actually know about the Nuckelavee?
We have good reason to think Dennison was recording an existing piece of Orcadian folklore, given his history of collecting oral traditions. But we can't be certain how much of his account was shaped by his own storytelling, and we still can't pin down the monster's origins or find another independent account of a sighting.1,2,3
I believe we have found enough connections to other malicious water-horse legends to reasonably assume that the eventual development of the Nuckelavee was at least related to these older water spirits, if not simply another variation of the same folklore.1,4,5,6
We also know that the historical record demonstrates some interesting connections between the story, the disease known as Mortasheen, and the kelp-burning industry in Orkney. Though we can't definitively prove how these events influenced the legend.1,7,8
It is also perhaps worth noting, for any modern-day monster hunters, that the Nuckelavee does in fact have weaknesses. In its own story, the creature has an aversion to fresh water, though the story does not demonstrate that freshwater could actually kill it. And if the creature shares more than a few characteristics with its cousins, the Neagle and the Water-Kelpie, it may even be possible to drive it away or kill it through the use of burning brands or red-hot iron, should the need arise.1,5,6
Overall, I think it's a fascinating story, and I wish I could have heard a firsthand telling of it myself, sitting around a campfire on a dark night.
Keep this story in mind the next time you have the chance to tell a scary story. I'm sure people will love it. And when they inevitably ask about its origins, you'll have some of the information you need to tell them a little about the fascinating folklore of Scotland's Northern Isles.
