The Mermaid: Myth, Symbol, and Enduring Obsession

Few figures in human imagination have proven as tenacious, as contradictory, and as genuinely haunting as the mermaid. She appears in the oldest surviving literature, on medieval maps, in Renaissance paintings, tattooed on the arms of sailors who had never seen the ocean, and in blockbuster films watched by children who grew up nowhere near the sea. She is everywhere, and yet she remains perpetually elusive — half-familiar, half-mysterious, like something glimpsed just beneath the surface of deep water before it closes over.

This post explores where the mermaid came from, why she refuses to go away, what she has meant to different cultures across the centuries, and why she continues to captivate artists, writers, filmmakers, and dreamers in the twenty-first century.

The Oldest Mermaids in the World

The story begins not with Hans Christian Andersen or Disney, but in ancient Assyria, roughly three thousand years ago. The goddess Atargatis was one of the most important deities of the ancient Near East — a goddess of fertility, water, and the moon. According to the oldest versions of her myth, she accidentally killed a human shepherd she had fallen in love with, and in her grief, she plunged into a lake to transform herself into a fish. The waters, however, could not contain her divine beauty, and she emerged with a human upper body and a fish’s tail. Temples to Atargatis were built across Syria and into the Greco-Roman world, where she was eventually merged with Aphrodite and Derceto, acquiring new layers of meaning with each cultural translation.

Around the same period, ancient Babylon was home to Oannes, a figure depicted as a man wrapped in a fish — sometimes interpreted as a kind of merman — who was said to have risen from the ocean to teach humanity the arts of civilization. The image of the half-human, half-fish being as a bridge between the terrestrial and aquatic worlds, between the known and the unknown, was already ancient long before the Greeks elaborated it into the Nereids and Tritons who populated their mythological seas.

In ancient Greece, the sea was conceived as a living, personality-rich domain, full of creatures that blurred the line between human and animal, mortal and divine. The Nereids were sea nymphs, fully humanoid but associated with the ocean in ways that later artists would render explicitly piscine. Triton, son of Poseidon, was depicted as a merman — his upper body human, his lower half the tail of a fish — and he wielded a conch shell whose sound could calm or raise the seas. These figures weren’t frightening in the way later mermaids would become; they were intermediaries, guides, and sometimes lovers.

Medieval Mermaids: Beauty, Danger, and Desire

When the mythology of the ancient world filtered into medieval European culture, the mermaid was transformed into something considerably more ambiguous. The Christian Middle Ages were deeply suspicious of the sea — a chaotic, ungovernable space that resisted the ordering principles of the Church — and the beings who inhabited it reflected that suspicion. Medieval mermaids were simultaneously beautiful and deadly. They sang to lure sailors onto rocks. They dragged men beneath the waves and drowned them in acts that could be read as punishment, seduction, or simple predation depending on the interpreter.

This duality shows up clearly in medieval bestiaries, illustrated manuscripts that catalogued both real and fantastical animals and drew moral lessons from each. The mermaid appears in these texts alongside unicorns and dragons, and the commentary is consistently cautionary: her beauty is a trap, her music a deception, her embrace a death sentence. She represented the dangers of earthly desire, the snare of sensory pleasure that led men away from God and reason. In this context, she became a kind of aquatic Eve — the feminine embodiment of temptation.

And yet she was also depicted in churches. Carved mermaids appear in the stonework of dozens of medieval European cathedrals, including Exeter Cathedral in England and the Cathedral of St. Brendan in Ireland. Some of these images are playful, even affectionate. The same culture that warned against the mermaid as a symbol of sin also couldn’t stop carving her into sacred spaces, which suggests something deeper at work than simple moral allegory — a genuine fascination that no amount of theological framing could fully contain.

The medieval figure of Melusine adds another layer. In French legend, Melusine was a woman who transformed into a serpent or fish-tailed creature each Saturday, a secret her husband swore never to investigate. When he inevitably broke his promise, she was forced to leave forever. Melusine is tragic rather than predatory — a being trapped between two worlds, fully at home in neither, and her story carries a melancholy weight that anticipates the more sentimental treatments of the mermaid that would come later. The noble house of Lusignan claimed Melusine as an ancestor, which tells you something about the prestige that could attach to this otherwise ambiguous figure.

The Age of Exploration and the Mermaid’s New Role

When European ships began crossing the Atlantic and Pacific in the fifteenth and sixteenth centuries, the mermaid’s cultural role shifted again. She appeared on maps — those extraordinary visual documents that mixed geographical knowledge with mythological speculation — as both a decoration and a warning. Cartographers placed mermaids in the margins of uncharted waters, often alongside sea monsters, to indicate zones of danger and mystery. She was the face of the unknown ocean, the marker that said: here be things we cannot explain.

Sailors reported actual mermaid sightings with surprising frequency during this period. Christopher Columbus, on his voyage to the Americas in 1493, recorded seeing three mermaids rise from the sea near what is now Haiti. He noted, with some disappointment, that they were not as beautiful as they were in paintings. Most historians believe Columbus saw manatees or dugongs, and his observation actually helps explain one of the great mysteries of mermaid lore: how ancient sailors, far from home and suffering from scurvy, dehydration, and the distorting effects of intense sunlight on open water, might have interpreted large marine mammals as humanoid figures.

The dugong and the manatee — both members of the order Sirenia, named after the Sirens of Greek mythology — have features that could, under the right conditions of distance and light, suggest a humanoid silhouette. Mother manatees nurse their young at the water’s surface in a vaguely cradling posture. Their tails are horizontal, like a whale’s, rather than vertical like a fish’s, but the broad outlines of the mermaid myth don’t require exact anatomical fidelity. What the sailor saw was a large, dark shape with what appeared to be a human upper form, and his mind supplied the rest from a catalogue of images he had grown up with.

This doesn’t make the mermaid sightings hoaxes, exactly — it makes them something more interesting: a meeting point between the limits of human perception and the extraordinary power of cultural expectation to shape what we think we see.

Hans Christian Andersen and the Mermaid’s Interior Life

The mermaid’s emotional register changed decisively in 1837 when the Danish writer Hans Christian Andersen published “The Little Mermaid.” The story is far darker than its Disney adaptation suggests. Andersen’s mermaid gives up her voice to a sea witch in exchange for legs, suffers agonizing pain with every step, fails to win the love of the prince she saved from drowning, and ultimately dissolves into sea foam rather than kill him to save herself. She does not get the happy ending.

What Andersen achieved that was genuinely new was a mermaid with a fully realized interior life — a creature who doesn’t just lure or threaten, but who wants and suffers and chooses. His mermaid is driven by an almost philosophical longing: she doesn’t just want the prince, she wants an immortal soul, the capacity for spiritual transcendence that Andersen’s story implies is the exclusive property of humans. The mermaid, in his telling, is caught between two modes of being and can fully inhabit neither. She sacrifices everything to become human and is still excluded from humanity’s deepest gift.

This theme of the mermaid as a figure of longing and impossible belonging would echo through the next two centuries of literature, art, and film. She became a way of talking about exile, about the desire to transform oneself, about the cost of assimilation, about what is lost when you cross the boundary between one world and another. She is, in this reading, a profoundly immigrant figure — someone who has left one home and cannot fully enter the new one.

The Little Mermaid statue in Copenhagen harbor, based on Andersen’s story, has been one of Denmark’s most visited landmarks since it was installed in 1913. It has also been repeatedly vandalized, decapitated, and subjected to political interventions over the years, which says something about how charged this figure remains — how much she still provokes, how much she still means.

Mermaids Around the World

The mermaid is not a European invention that was exported everywhere else. Similar figures appear independently across the globe, which suggests she speaks to something fundamental in human experience rather than simply being a piece of portable folklore.

In West African Yoruba tradition, Mami Wata is a water spirit who appears as a beautiful woman, often with a fish’s tail, who is associated with water, fertility, and healing. She is not the same figure as the European mermaid, but she shares the broad outlines: the irresistible feminine beauty, the ambiguous relationship with humans who encounter her, the power to give and take away. Mami Wata traditions are alive today not just in West Africa but in the African diaspora communities of the Caribbean and the Americas, where they merged with other spiritual traditions to produce complex, living mythologies.

Japan has the ningyo, a fish-human creature of considerable antiquity whose flesh was said to grant immortality to anyone who ate it. The ningyo is not particularly beautiful in most traditional depictions — she’s more eerie than alluring — and her appearance was considered an omen of misfortune and war. In Scotland and Ireland, the selkie tradition imagines shape-shifting beings who are seals in the ocean and humans on land; they’re closely related to the mermaid emotionally if not anatomically, and their folklore is similarly saturated with themes of longing, transformation, and the impossibility of belonging to two worlds simultaneously.

The Caribbean figure of Lasyrenn is a mermaid goddess in Haitian Vodou, a keeper of hidden knowledge who lives beneath the surface of the sea and whose encounters with humans can be transformative or devastating. In China, historical texts describe a creature called the jiaoren, a fish-tailed humanoid whose tears, if caught in a bowl, would turn to pearls.

What unites these traditions across their enormous differences is the sea itself: its power, its mystery, and its ancient status as the boundary between the known and the unknown, the living and the dead, the human world and whatever lies beyond it.

The Modern Mermaid: Reclamation and Reinvention

By the late twentieth and early twenty-first centuries, the mermaid had been through enough cultural translations to have accumulated a genuinely remarkable range of possible meanings. Disney’s 1989 film “The Little Mermaid” restored the happy ending Andersen had withheld, transforming the story into a coming-of-age narrative about a young woman’s desire for independence — which some read as empowering and others read as problematic, depending on whether you focus on Ariel’s determination or on the fact that she literally gives up her voice to pursue a man.

More recently, the mermaid has become a figure of queer reclamation. She is neither fully one thing nor another — she occupies the border between identities — and this ambiguity has made her a resonant symbol for people who feel themselves to be living between categories, whether those categories are gendered, sexual, or cultural. The “mermaiding” subculture, in which participants wear elaborate fabric tails and swim in pools or the ocean, is part performance art, part athletic practice, and part identity exploration, and it draws from a community that is notably diverse in its gender and sexual composition.

Black mermaid representation has been a particularly significant recent development. When actress Halle Bailey, who is Black, was cast as Ariel in the 2023 live-action remake of “The Little Mermaid,” the announcement was met with both enthusiastic support and ugly racist backlash. The support, which was overwhelming in spaces where Black women and girls shared their responses to seeing themselves reflected in this iconic image, spoke to something real: the mermaid as a figure of wonder and longing is not the exclusive property of any single cultural tradition, and the stories we tell about her shape who gets to dream through her.

The mermaid has also become a major presence in contemporary fantasy literature, from literary novels that use the mermaid myth to explore themes of identity and belonging, to young adult fiction that reimagines her as a warrior or a villain or a survivor. She appears in video games, in fine art, in fashion design, in the names of coffee companies. She is on the Starbucks logo, which is actually a siren — a variant of the same tradition — adapted from a sixteenth-century Norse woodcut.

Why the Mermaid Endures

After three thousand years, the mermaid shows no sign of losing her hold on the human imagination. It’s worth asking why.

Part of the answer is the ocean itself. The sea covers more than seventy percent of the Earth’s surface, most of it unexplored. It is the origin of all life on this planet. It is the place where we came from and where many of us will eventually be deposited, one way or another. The mermaid lives at the boundary of our world and the world we cannot inhabit — she represents everything we can look toward but not enter, everything that draws us and resists us simultaneously. That is a genuinely inexhaustible set of meanings.

Part of the answer is her formal ambiguity. She is literally two things at once, and the tension between those two things generates story, emotion, and symbol with remarkable efficiency. Every version of the mermaid tale is, at its heart, a story about what it costs to want to be something other than what you are — and almost every human being alive has felt that wanting at some point.

Part of the answer is surely the beauty and strangeness of the image itself: that impossible, luminous figure just beneath the surface, looking up. The mermaid is something we almost understand, almost recognize, almost can reach — and that “almost” is where all the most interesting things in art and imagination live.

She has been a goddess, a warning, a temptation, a martyr, a symbol of exile, an emblem of queer identity, a corporate logo, and a childhood dream. She contains multitudes. And wherever there are oceans, and humans to look at them and wonder what lives beneath the surface, she will keep appearing — rising up just long enough to be glimpsed, then slipping back into the deep.
