Four linked tales — Pwyll, Branwen, Manawydan and Math — written in Wales around the eleventh or twelfth century and preserved in two great medieval books. They are the finest prose of the medieval Welsh, and one of the oldest bodies of story in any vernacular European literature: a world of demoted gods walking as kings, of the Otherworld a horse-ride away, of cauldrons and curses and shape-shifting, told in a clear, swift, ironic voice that has never gone out of date. Each branch lives here as a full deep-read; this hub holds the history of the work that binds them.
A prince trades places with the lord of the Otherworld; wins Rhiannon, the fairy bride on the white horse; outwits a rival with the badger-in-the-bag; and recovers a stolen son, named Pryderi.

Each of the four tales ends with the same colophon: ac yfelly y terfyna y geing honn o'r Mabinogi — "and so ends this branch of the Mabinogi." The Welsh word is cainc, a "branch" or strand (as of a rope or a piece of music), and the four together are Pedair Cainc y Mabinogi, the Four Branches of the Mabinogi.
The familiar English title Mabinogion is, strictly, a mistake — a fertile one. The word appears exactly once in the medieval manuscripts, at the end of the First Branch, where a scribe wrote mabynogion, almost certainly a slip for mabynogi. Lady Charlotte Guest, making the first full English translation in the 1840s, took it for a genuine plural and used it as the title for her whole collection of eleven Welsh tales — and it stuck. So Mabinogion now means the wider gathering of medieval Welsh prose tales; Mabinogi proper means only the Four Branches.
What mabinogi itself meant is still argued. The root is mab, "son, boy, youth." It may mean a "tale of youth" or a story fit for the training of a young cyfarwydd (a professional storyteller); or — the reading many favour — "the tales of the family of Maponos," the British boy-god whose Welsh name is Mabon, son of Modron (the goddess Matrona). On that reading the very title points back to the divine substratum the branches are made of.
The Four Branches survive complete in two of the great medieval Welsh manuscripts, neither a copy of the other — both descend from lost earlier exemplars:
The tales are far older than the manuscripts. Behind them lies a long oral tradition — the stock of the cyfarwydd, the court storyteller — reaching back into the British Iron Age and beyond. The written form they now have is usually placed in the late eleventh or twelfth century (estimates run from c. 1060 to c. 1200), making them among the earliest prose narratives in any European vernacular, and roughly contemporary with — or earlier than — the first Continental romances.
No author is named, and the question is genuinely open. The shaping intelligence behind the four — the cross-references, the recurring figures, the deliberate symmetry — has led many scholars, since Ifor Williams's foundational 1930 edition, to argue for a single author who gathered and re-formed inherited material into one tetralogy. That a single mind shaped the work is widely felt; who that mind was remains unproven. Named candidates have been proposed — the cleric Rhigyfarch of Llanbadarn, and (more recently and far more contentiously) the princess Gwenllian ferch Gruffudd — but none commands consensus, and the safest statement is the honest one: the Four Branches are anonymous, and probably the work of one extraordinarily skilful redactor of much older story.
The Four Branches are euhemerised myth: they take what were once the gods of the Brittonic world and present them, without comment, as the lords and ladies of an ancient Wales. The audience was expected to feel the older weight under the human surface. Two great kindreds divide the cycle between them, like the two divine races of Irish myth:
| Figure | In the branches | The god beneath |
|---|---|---|
| Rhiannon | Fairy bride of Pwyll, mother of Pryderi; rides a white horse none can catch (Pwyll, Manawydan) | Rigantona, "Great Queen"; the horse-goddess Epona |
| Brân & Manawydan | The giant-king and his brother, children of Llŷr (Branwen, Manawydan) | The sons of Llŷr = Irish Lir; Manawydan = the sea-god Manannán mac Lir |
| Lleu Llaw Gyffes | The boy named, armed and wived against his mother's curses (Math) | Lugus — Irish Lugh, Gaulish Lugus, the pan-Celtic god of light and skill |
| The children of Dôn | Math's magician-kindred: Gwydion, Gilfaethwy, Aranrhod, Gofannon (Math) | The family of the goddess Dôn = Irish Danu; the Welsh Túatha Dé Danann |
| Mabon ap Modron | Named across the wider Mabinogion; the divine youth | Maponos son of Matrona — and perhaps the very root of the word mabinogi |
| Arawn & Annwn | The Otherworld and its courteous king, entered by Pwyll; source of the swine in Math | Annwn, the Brittonic Otherworld — not an underworld of the dead but a parallel realm |
The genius of the branches is that none of this is ever explained. Arawn is simply a king, Rhiannon simply a lady, Lleu simply a clever boy — and the audience is trusted to hear the gods underneath.
If anything makes the Four Branches a single composition rather than four loose tales, it is Pryderi. He is the only character to appear in every branch — never quite the hero, but always there, the connecting thread the redactor draws from the first page to the fourth:
| Branch | Pryderi's part |
|---|---|
| I · Pwyll | Born, lost and recovered. Stolen as a newborn, raised in secret by Teirnon, restored to Pwyll and Rhiannon, and named Pryderi ("care/anxiety") for the trouble of his loss. |
| II · Branwen | A survivor. One of the seven who alone come home alive from the catastrophe in Ireland, bearing Brân's living head. |
| III · Manawydan | Lord and victim. He gives his friend Manawydan the kingdom of Dyfed and his own mother Rhiannon in marriage — then is swallowed, with Rhiannon, by the enchanted caer until Manawydan wins them back. |
| IV · Math | Killed. Defrauded of his Otherworld swine and slain by Gwydion's magic in single combat — the death that ends the thread, and the line of Pwyll with it. |
Read together, the four trace the whole arc of a single life and lineage — born in the First Branch, dead in the Fourth — while the kindreds shift around him: the house of Llŷr rises and is broken in the Second, the house of Dôn rises in the Fourth. The cycle ends not on Pryderi but on Lleu, the bright god settling into kingship as the older line goes out.
| Pwyll | Branwen | Manawydan | Math | |
|---|---|---|---|---|
| Realm | Dyfed & Annwn | Britain & Ireland | Dyfed (the wasteland) | Gwynedd |
| Divine house | Rhiannon (Rigantona) | The children of Llŷr | Manawydan (Manannán) | The children of Dôn |
| Dominant mode | Exchange & courtesy | Tragedy & war | Patience & wit | Trickery & transformation |
| The marvellous object | Rhiannon's bottomless bag | The Cauldron of Rebirth | The golden bowl / the caer | The wand (hudlath) |
| Otherworld as… | A court ruled from within | The timeless feast at Gwales | A vanishing trap-fort | The source of the swine |
| The wronged woman | Rhiannon (calumniated) | Branwen (persecuted) | — (Cigfa kept safe) | Goewin (violated); Aranrhod |
| Ends on | A son restored & named | Graves & a buried head | The land made whole | An eagle made man; a new king |
| Onomastic close | The naming of Pryderi | Tal Ebolyon | Mynweir & Mynordd | Llech Gronw; the owl's name |
The branches have never stopped breeding new work. Blodeuwedd, the woman made of flowers and unmade into an owl, alone gave rise to Saunders Lewis's verse-play Blodeuwedd and Alan Garner's novel The Owl Service (1967); the cycle fed Robert Graves's The White Goddess, Evangeline Walton's four novels, Lloyd Alexander's Prydain books, and a continuing stream of Welsh-language drama, poetry and song. The oldest prose of Wales is also among its most alive.
