The supplied sources do not record a single cosmogonic origin tale for the ceffyl dŵr. In Welsh folkloric accounts it is presented as a water‑bound spirit or otherworldly horse associated with bodies of water and weather; comparative discussion places it within a family of Celtic water‑horse beings (e.g., Scottish each-uisge, Irish each uisce/púca, Manx glaistyn). There is no unified origin myth in the provided materials.
Folklore portrays the ceffyl dŵr most commonly in a horse form, with regional variation in colour and size. Descriptions include grey or black horses (sometimes with a white mane), luminescent or glowing examples, winged variants, dapple-grey or sand‑coloured forms on seashores, large chestnut or piebald animals in some areas, and at least one tale of a miniature black horse with a white mane. Aberrant features such as hooves turned the wrong way are noted in seaside sightings. Sources also record occasional shapeshifting into other animals (goat, frog) used in harmful episodes.
Across the collected accounts the ceffyl dŵr is a shapeshifter and agency-bearing water spirit. Common folkloric motifs attribute to it the power to entice travellers to mount and then carry them at extreme speed over great distances, sometimes flying into the sky and then evaporating into mist so that riders fall to their deaths. It may be captured and put to work in tales but is said to eventually escape and drag its captor to death—typically into water. Regional variation is emphasised: northern accounts tend to portray it as malevolent (fiery eyes, forbidding), while some southern accounts present it as ambivalent or occasionally helpful.

Each-Uisge
The most dangerous water horse in Scottish Highland folklore — haunting sea-lochs and mountain lakes, more violent than the river kelpie, known for consuming its victims whole.
Kelpie
A Scottish shape-shifting water horse that appears as a beautiful tame horse near lochs and rivers, then drowns and devours any rider foolish enough to mount it.
Abandinus
Abandinus is a locally attested Romano‑Celtic theonym known from a single inscribed bronze feather (votive object) dedicated at Godmanchester (the Roman fort Durovigutum) in Cambridgeshire. Scholars interpret him as a local god or male spirit tied to a specific place and possibly associated with a nearby spring or stream; this association is tentative and based on etymological readings of the name.
Abarta (Ábartach)
Abarta (also Ábartach) is a figure of Irish myth who, in surviving accounts, tricks Fionn mac Cumhaill's warriors by giving them a supernatural grey horse that bears them into the Otherworld. Sources variably identify him as a member of the Tuatha Dé Danann or as a Fomorian; after the incident he is compelled to release the captured warriors and is refused entry to the Fianna.
Abcán (Abhcán)
Abcán (modern spelling Abhcán) is a named dwarf poet and musician of the Tuatha Dé Danann in Irish myth. He appears in a small number of narratives as a musician whose art has soporific power and as the ferryman who brings the goddess Ruad from the Otherworld to the human world.
Abhean
Abhean is a named poet of the Tuatha Dé Danann in medieval Irish literature, described as a poet in particular of Lugh and recorded as having been killed by Óengus before Midir in a poem by Fland Mainistreach preserved in the Lebor Gabála Érenn.
Abnoba
Abnoba is a Gaulish theonym and toponym attested in Roman-era sources and inscriptions: a localized deity associated with woods, springs and the sources of rivers (notably the Danube) and simultaneously the name applied to a mountain or mountain range in the Black Forest/Baar/Odenwald region. Roman altars equate her with Diana, reflecting syncretic cult practice in frontier provinces.
Accolon
Accolon is a mortal knight of the Arthurian court, presented in the Post-Vulgate Merlin tradition and Malory's Le Morte d'Arthur as Morgan le Fay's paramour and instrument in a plot to supplant King Arthur; his tale centers on enchanted weapons (Excalibur and its scabbard), love-manipulation, and a tragic duel with Arthur.
Achall
Achall is an eponymous mortal woman in the Ulster Cycle of early Irish literature whose grief-induced death is given as the origin of the hill-name Achall (identified with the modern Hill of Skryne). She appears as a genealogical and etiological figure tied to Tara and later legendary events at the hill, rather than as a recurring supernatural agent.
Achtland
Achtland is a figure from Irish tradition who, according to the surviving account, was a mortal woman famed for rejecting mortal suitors who married a member of the Tuatha Dé Danann and crossed into the síde to become immortal as his wife.
Adar Llwch Gwin
Legendary large, intelligent birds from Welsh tradition said to understand human speech and obey their master's commands; best known for tearing their master Drudwas ap Tryffin to pieces when bound by a literal order in an Arthurian battle narrative. The term later came to be applied to raptors and metaphorically to brave men in medieval Welsh poetry.
Adar Rhiannon
Adar Rhiannon ('birds of Rhiannon') are a set of three magical birds in medieval Welsh narrative (the Mabinogi) whose song can 'wake the dead and lull the living to sleep.' They appear as otherworldly song‑beings tied to the figure Rhiannon and function within tales as providers of enchanted music that sustains and consoles characters.
Aderyn y Corff
Aderyn y Corff (literally 'bird of the corpse') is a bird-like death-porter in Welsh folklore said to call outside the door of a person about to die. Described as an avian portent that may lack feathers or wings and as existing on another plane when not manifesting, it is treated in Welsh ghost lore and sometimes naturalized as a screech owl in modern accounts.
Adhene
A class of Manx fairies (Cloan ny moyrn) described in Isle of Man tradition as a social people of beings said to be "fallen angels cast from heaven but too good for hell," who interact with human livelihoods and families, sometimes benevolent but often mischievous.
