Dôn

Also Known As: also Don; the name’s origin is disputed, derived either from Proto-Celtic *Dānu, a river word, or from Proto-Indo-European *dʰéǵʰōm, “earth”
Region/Culture: Northern Europe
Mythos: Welsh Mythology, Celtic Mythology
Primary Type/Nature: Gods and Deities
Mythical Attributes: She confers identity rather than exercising power, since every one of her children is known by her name and not their father’s.
Role in Mythos: She is the ancestress of the divine family whose quarrels, magic and crafts fill the Fourth Branch of the Mabinogi.
Relation to Humans: Nothing in the record connects her to worship, offering or petition, and no site in Wales is named for her except the sky. The medieval Welsh dynasties of Gwynedd nonetheless traced power and legitimacy through exactly the kind of maternal line she represents.

On a clear winter night above the Arfon coast, the constellation most of Europe calls Cassiopeia hangs over the black bulk of the mountains, and the Welsh name for it is Llys Dôn, the Court of Dôn. Her son holds the Milky Way, Caer Gwydion. Her daughter holds Corona Borealis, Caer Arianrhod. The entire family is up there in the cold, laid out across the sky in fortresses and halls, and the woman at the centre of the arrangement does not appear in a single surviving story.

What survives instead is her name inside other people’s names. The Fourth Branch of the Mabinogi opens with the old king Math son of Mathonwy unable to tour his own kingdom, bound by some condition the text never bothers to explain to sit with his feet in the lap of a virgin except when war calls him out. The circuit of Gwynedd is ridden in his place by his nephews, and the storyteller introduces them as Gilfaethwy son of Dôn and Gwydion son of Dôn, sons of his sister. Their father is never mentioned. Not once, in a literature that names fathers with the persistence of a land registry. Two young men ride hall to hall through the mud of a Welsh autumn collecting the king’s dues, and at every threshold they are announced by their mother.

She has no myth of her own.

What she has is consequences. Gilfaethwy wants Goewin, the girl who holds Math’s feet, and Gwydion arranges a war to get her alone, tricking Pryderi of the south out of a herd of otherworldly pigs and provoking the fighting that draws his uncle away. While the armies are in the field, Gilfaethwy takes Goewin by force in the king’s own bed. Math’s answer is the strangest punishment in Welsh literature: he strikes his nephews with his wand and turns them into deer, then boar, then wolves, a year in each shape, and makes them mate with each other and bear each other’s young. Each year the pair are driven back to court with a squealing, bellowing offspring at heel, and each year the wand comes down again and returns them briefly to their own skins. The stink of the animals is in the hall. Their mother’s name is on both of them throughout.

The genealogists filled the family out. A tract known as the Hanesyn Hen heads a list Plant Dôn o Arfon, the Children of Dôn of Arfon, and gives fourteen names: Addien, Amaethon, Arianrhod, Cyman, Digant, Elawg, Elestron, Gilfaethwy, Gofannon, Gwydion, Hedd, Hunog, Idwal and Iewydd. Several of these are simply ordinary Welsh words wearing a capital letter. Addien means fair, Cyman means perfect, Hedd means peace, Hunog means sleepy. The list has the texture of a household expanded to a pleasing number by someone who had run out of real people. The five who kept their stories are the ones worth knowing: Gwydion the magician, Arianrhod who refuses to name or arm her son, Gilfaethwy, and the two craftsmen. In Culhwch and Olwen the giant Ysbaddaden sets a task that turns on both craftsmen at once. A stretch of wild ground must be cleared, burned, ploughed, sown and reaped between dawn and dusk, and only Amaethon son of Dôn can break that soil, and only Gofannon son of Dôn will come down to the headland and fit the iron edge to the share. The giant adds, with obvious satisfaction, that Gofannon will not do the work willingly for anyone but a rightful king.

The awkward part comes when you ask who she was, because the early Welsh material does not say whether Dôn was these children’s mother or their father. It simply gives the name. Medieval and early modern Welsh scribes read it as a man’s, without apparent difficulty. One manuscript puts Don ap Conwy at the head of a list of Dôn’s own children. A copy made in 1634 offers Don ap Dygyn ferthyr o Arfon. Edward Lhuyd’s parish notes remark, flatly, that this Don was an usurper. Lewis Morris wrote that Don, lord of Arfon, was the father of Gwydion. Iolo Morganwg, a man who invented Welsh antiquity wholesale when the real thing disappointed him, went further and made Dôn a king of Llychlyn and Dulyn, Scandinavia and Dublin, leading the Gwyddyl into Môn and Arfon.

The goddess is a Victorian settlement. In his Hibbert Lectures of 1886 John Rhys read the name as feminine without hesitating, identified her with the Irish Danu whose people are the Tuatha Dé Danann, and, because a triad calls Arianrhod the daughter of Beli, made Dôn the consort of Beli Mawr. That reading has held ever since and sits in most reference works today, though W. J. Gruffydd recorded his doubts in 1928, and Peter Bartrum pointed out the obvious hole: nothing licenses the assumption that Beli fathered all of Dôn’s children or that Dôn bore all of Beli’s. The etymology is no steadier. Rhys’s river word gives the Danube, the Don and the Dnieper and a great Indo-European water goddess behind them all. John Koch argues the sounds do not work and prefers a root meaning earth, which would make her the ground itself rather than the flood over it. Either is a fine ancestress. Neither can be proved from anything actually written in Welsh.

Her one recorded power is genealogical, and it is not nothing. To be a child of Dôn in the Fourth Branch is to be placed instantly: north Welsh, magically gifted, dangerous, kin to the king. The limits are severe. She has no shrine, no feast, no offering, no petitioners, no line of dialogue and no scene. She cannot enter the stories that depend on her. And because nothing in the oldest sources fixes her sex, a copyist with a slip of the pen could turn her into a man, and several of them did, for roughly four hundred years before a professor of Celtic turned her back.

Llys Dôn is still the Welsh name for Cassiopeia. It is a court with nobody sitting in it.

Frequently Asked Questions

Who is Dôn in Welsh mythology?

Dôn is the ancestor figure of the divine family known as the Children of Dôn, whose members dominate the Fourth Branch of the Mabinogi. Her children include Gwydion the magician, Arianrhod, Gilfaethwy, Amaethon the ploughman and Gofannon the smith. She is named constantly in genealogies and patronymics but never appears as a character in any surviving story.

Was Dôn a goddess or a god?

The oldest Welsh sources do not say whether Dôn was the mother or the father of the Children of Dôn. Medieval and early modern Welsh antiquarians generally read the name as a man’s, producing forms like “Don ap Conwy” and Lewis Morris’s statement that “Don, lord of Arfon, was father of Gwydion”. The identification of Dôn as a mother goddess comes from John Rhys in 1886 and has been the standard reading ever since.

Is Dôn the same as the Irish goddess Danu?

John Rhys equated the two, and that equation is still widely repeated, but it is disputed. The Irish name is usually connected to a word for river, seen in the Danube, the Don and the Dnieper, while John Koch has argued the Welsh form cannot come from that root and derives instead from a word meaning “earth”. The two figures play similar roles as ancestresses of a divine family, but the linguistic link is not secure.

Who are the Children of Dôn?

The best-known are Gwydion, Arianrhod, Gilfaethwy, Amaethon and Gofannon. A genealogical tract listing the Plant Dôn o Arfon names fourteen in total, adding Addien, Cyman, Digant, Elawg, Elestron, Hedd, Hunog, Idwal and Iewydd, several of which are ordinary Welsh words rather than characters with stories. They are consistently associated with Arfon and Gwynedd in north-west Wales.

What is Llys Dôn?

Llys Dôn, “the Court of Dôn”, is the traditional Welsh name for the constellation Cassiopeia. Two of her children carry similar names in the Welsh sky: Caer Gwydion is the Milky Way and Caer Arianrhod is Corona Borealis. It is one of the few places outside the manuscripts where Dôn’s name is still in everyday use.
