A water fairy of English story, usually taking a woman's form and living in lakes, kin to the mermaid. Its status as old folk belief is doubted: the oldest trace is an 1872 poem by Robert Williams Buchanan, and later collected tales seem to echo his verse.
- First appears in print in Robert Williams Buchanan's poem The Asrai, published in 1872
- Told to rise from its lake once every hundred years, to bathe under the moon
- Sunlight is said to destroy it: one caught asrai melted to a puddle in a boat
- Ruth Tongue's collected asrai tales are widely doubted as records of folk belief
- Green-haired, shy and web-footed, it stands two to four feet tall in one description
What it is
The asrai is a water fairy told of in English story and story-books. It takes a woman's shape, lives under lake water, and tellers group it with mermaids and with nixies, another water being. In the verse where it first appears it is pale and mild, older than humankind, hiding from light at the bottom of its lake. Later collections make it timid and very beautiful, green-haired and web-footed, and one writer describes them as always female and two to four feet tall. Their lives are said to run to several hundred years. A retelling by Rosalind Kerven gives the asrai a fishtail in place of legs. Moonlight shapes its whole existence, and sunshine is said to end it.
Where it comes from
The word itself is a puzzle: nothing certain is known about where 'asrai' comes from, and the spellings 'asrey' and 'ashray' also appear. Its oldest trace in print is a poem, The Asrai, by the Scottish poet Robert Williams Buchanan, printed in April 1872. A second poem, The Changeling, followed in 1875, commissioned by the English journalist Robert Francillon for a Christmas number of The Gentleman's Magazine. Francillon had hoped for a piece built on the legends of Llyn Tegid, or Bala Lake, in Wales, but he later judged that Buchanan had ignored his suggestions and invented a myth entirely his own. Whether the asrai ever lived in ordinary folk belief is unclear, so its real starting point may be a single Victorian poem.

What it is for
No one prays to the asrai or works spells with it; in the tales, it is the lake itself that acts. In Kerven's retelling, the asrai tries to draw a man into the deepest water with talk of gold and jewels, meaning either to drown him or to cheat him. Coarse or vulgar speech from a human, though, will drive her off. In Tongue's account, a captured asrai pleads for freedom in a language no one understands, and its cold, damp hands scald the fisherman's skin as fire would, marking him for life. Meeting one, the stories suggest, brings danger or loss, never gift.
Peoples and places
The asrai belongs to English story, with a Welsh edge: the legend behind the poem commission came from Bala Lake, and Ruth Tongue set her asrai tales in Cheshire, Shropshire and along the Welsh Border. She was a British storyteller and collector whose work brought the creature back into notice a century after Buchanan. Nancy Arrowsmith's portrait of the creature as always female and two to four feet tall has travelled through many collections. Because Tongue's sourcing is disputed, scholars treat these county attributions as part of the story's literary life rather than evidence of local custom.
At a glance: who, where and when
What people believe
The stories give the asrai firm rules. It dwells beneath its lake, fears light, and belongs to a world older than humankind. In Buchanan's The Changeling, a male asrai enters a human body and lives as a changeling, wanting what humans have: an immortal soul. Moon and sun govern it in opposite ways: moonlight is when it surfaces, once every hundred years, and moonlight is the only thing that ages it. Sunlight destroys it. In Tongue's telling, a fisherman who catches one covers it with wet weeds for the journey, but it protests in a fading voice until, at the shore, only a puddle remains.
When it is done
The asrai keeps a calendar of centuries, not seasons. It is said to surface once every hundred years, to bathe while the moon shines, and moonlight is the only thing that ages it. The rest of its long life is spent below, out of the light. The only dated occasion attached to it is a human one: a Christmas number of a magazine, in which the second poem about the creature appeared.
How scholars and sceptics see it
Scholars read the asrai as a creature of books rather than of oral tradition. Sarah Allison argues that its earliest and clearest source is Buchanan's nineteenth-century verse, and Francillon's later account supports that: he said Buchanan ignored the Bala Lake material and built a myth of his own making. Ruth Tongue's collecting is doubted too. Researchers have pointed out that her tales often borrow from popular fiction, and that she could pass off stories she made up or stitched together as genuine tradition. Several details of her asrai, including its trouble with moonlight and its melting, closely echo Buchanan's images. On this reading, Tongue's versions are literary reworkings, not records of an older belief, and the asrai is a modern myth that took shape as Victorian verse and later retellings in folk-tale dress kept answering one another across the twentieth century.
Compare and confuse
The asrai is repeatedly set beside water beings of wider story: the mermaid and the nixie. Its failure in daylight recalls Scandinavian trolls, which share the same frailty. One tale told of the asrai, in which it lures a man toward the deepest water with offers of gold and jewels, was earlier attached to a mermaid of Shropshire, before the name asrai existed for it. The second Buchanan poem also ties it to changelings, through a male asrai living inside a human body.
Today
The asrai now lives mostly on the page. Numerous collections of folk tales have reprinted or retold Ruth Tongue's stories, and the creature is often presented as traditional English or Welsh folklore, although the evidence for older belief behind it is thin. Tongue's work renewed interest in the being, and her versions supply most of the details now attached to it, from the green hair to the melting. On the current evidence, the asrai found in modern fairy anthologies is a literary water spirit wearing folk-tale dress rather than a documented local legend.
Questions people ask about Asrai
What is an asrai?
A water fairy of English tale, taking a woman's form and living in lakes. In one set of stories it is shy and beautiful, with green hair and webbed feet, rising once a century to bathe in moonlight. Some tellings give it a fishtail in place of legs, and one writer has it two to four feet tall.
Where does the asrai come from?
Its oldest known trace is a poem, The Asrai, by the Scottish poet Robert Williams Buchanan, printed in April 1872, with a follow-up poem in 1875. The editor who commissioned that second piece said Buchanan invented the whole matter, so the being may come from Victorian verse rather than from folk belief.
Is the asrai genuine old folklore?
Scholars doubt it. Sarah Allison calls Buchanan's poetry the earliest and clearest source, and Ruth Tongue's later collected tales are widely questioned: researchers note borrowings from popular fiction and details that mirror Buchanan's images. The asrai is best read as a modern myth, passed back and forth between printed stories and retellings dressed as old folk tales.
What happens if you catch one, in the stories?
In a tale recorded by Ruth Tongue, a fisherman who captured an asrai heard it plead in a language he did not know; its cold, damp hands scalded his skin as fire would, and by the time he reached shore it had melted into a puddle, for sunlight destroys the creature.
How is the asrai different from a mermaid?
They are close kin in the tales, and one asrai story was earlier told of a mermaid from Shropshire without the name. The asrai is described as smaller, two to four feet tall, pale and shy, with green hair and webbed feet; one retelling gives it a fishtail in place of legs.
