This is a collection of four interconnected Welsh prose tales preserved in medieval manuscript and first published in English translation by Lady Charlotte Guest between 1838 and 1849. The stories draw their language from the twelfth or thirteenth century, though their mythical content reaches back much further—to a time when Celtic gods and heroes still inhabited the imagination of Welsh bards. What we encounter in these branches is not myth in its original sacred form, but myth reshaped into narrative material for a learned literary caste: the bards who were obliged to preserve and transmit the heroic and legendary traditions of their people.
The Story
The Four Branches and Their Origins
The tales known as the Mabinogion entered European letters through Lady Charlotte Guest’s publication between 1838 and 1849, when she rendered into English eleven old Welsh prose narratives drawn chiefly from the Red Book of Hergest, a fourteenth-century manuscript of mixed contents. Yet only four of these tales merit the name Mabinogi in its truest sense—a designation rooted in the bardic tradition, where a Mabinogi was both the apprentice who learned the craft and the body of mythical and historical material he was obliged to preserve. These four branches constitute a collection of such traditional matter, comparable to the Eddic songs compiled by the Icelandic Snorri Sturluson for the use of skalds: remnants of a literature created by a literary caste whose fixed duty was to guard the mythical and heroic inheritance of their people.
The linguistic evidence points to composition near the end of the twelfth century or the beginning of the thirteenth, though the actual origin of their fables lies much deeper in time—likely the tenth and eleventh centuries. Unlike the other tales in the Red Book, these four show no trace of Arthurian influence, a mark of their antiquity before the Norman conquest of England transformed the narrative poetry of Western and Central Europe. They stand almost alone as documents of epic prose from their age, shaped from an enormous body of legend that had crystallized into literary form centuries before.
The four branches form not a continuous epic bound by a single hero’s fate, but rather a cyclic arrangement drawn from a common legendary corpus. Pwyll’s birth opens the sequence; his struggles and sufferings occupy the second and third branches; his final war and death conclude the fourth. Yet between these tales no natural continuity prevails. Pryderi, the figure who connects them, never stands at the center of any—he remains shadowed by his father Pwyll, then by his overlord Bendigeidfran, then by his companion Manawyddan, and finally by his enemy. The arrangement is one of legendary material organized by tradition rather than by the organic development of heroic action.
The Mythic Substrate Beneath the Tales
Beneath the medieval narrative lies an older stratum: early Celtic mythology, preserved in names and deeds that proclaim the former divine nature of these heroes. Manawyddan son of Llyr is evidently the Irish god Manannan son of Lir, magic-skilled and otherworldly; the sons of Don recall the Tuatha De Danaan, the divine race of the goddess Danu. Yet the Celtic gods were never set apart from humanity in the manner of Olympian deities—they remained essentially bound to the human realm, and the atmosphere of secret power and magic that surrounds these heroes speaks to their mythic origin, even as the medieval storytellers had grown distant from the sacred reality myth once embodied.
For the bards who composed the Mabinogion, myth had become poetic material rather than cosmic truth—though material in which the racial tradition they were sworn to preserve still lived. As Matthew Arnold observed, the medieval storyteller pillages an antiquity whose secret he no longer fully possesses, like a peasant building his hut upon the ruins of Halicarnassus, using stones of an older, greater, more majestic architecture whose history he knows only through dimming tradition. Yet Arnold’s simile does not entirely capture the truth: however estranged the creators of the Mabinogion had become from the holy power of myth, they served another power that lived in them with pure force.
Pwyll’s Enchanted Meeting
One afternoon at the hilltop of Arberth, Pwyll sits with his retinue when a woman in strange garb rides past on the road below. Struck by her beauty, he sends his squire for his horse and spurs, then pursues her at full gallop—yet no matter how swiftly his horse runs, he draws no nearer. In desperation he calls out, begging her by the man she loves most to wait. She halts, throws back her veil, and fixes her gaze upon him. She is Rhiannon, daughter of Heveydd the Old, and she has come seeking him alone. A man against her will is to be given her in marriage, yet she has taken no husband out of love for Pwyll, and will take none unless he rejects her. He declares that if he could choose among all the women in the world, he would choose her. She sets a tryst: a year hence, a feast shall be prepared for his reception at her father’s court, and there she will receive his answer.
The year passes at Arberth. When the appointed time arrives, Pwyll takes counsel with a hundred knights and journeys to the court of Heveydd the Old, where he is received with great joy and feasting. At table, Heveydd sits on one side of Pwyll and Rhiannon on the other, each according to rank. But as they drink, a tall youth of princely bearing enters in silk garments and greets Pwyll’s company. He is a suitor, he announces, come to beg a boon. Pwyll, in courtesy, grants whatever he can give. The stranger then reveals his request: he wishes to lie with the woman Pwyll loves most, and to claim the feast and all its provisions from him. Pwyll falls silent, unable to answer.
Rhiannon’s Cunning and the Year’s Delay
Rhiannon breaks the silence, declaring she has never seen a man display such dullness of wit. The stranger is Gwawl son of Clud, a mighty and rich man—the very suitor to whom she was to be given against her will. Since Pwyll has spoken his word before these nobles, he must yield her, lest shame fall upon him. But Rhiannon refuses to accept this counsel. She will contrive, she says, that Gwawl never receives her, and she instructs Pwyll in her plan. She will place a small bag in his hand, which he must keep well. When Gwawl claims the feast and its provisions, Pwyll shall answer that none of it is his own—she will distribute it to the retinue and household. As for herself, she will set Gwawl a term of one year from this evening before he may lie with her.
At the year’s end, Pwyll shall come with his hundred knights to the orchard. When Gwawl is deep in amusement and carousing, Pwyll shall enter dressed as a beggar, the bag in his hand, asking only that Gwawl fill it with food. No matter how much is placed within—even if all the food and drink of seven cantrefs were poured in—the bag will never grow fuller. When Gwawl, astonished, asks whether it will ever be full, Pwyll shall answer that it will not, unless a man of noble birth treads the food down with his feet and declares, “Enough has been put in here.” Then Gwawl, eager to end the marvel, will step into the bag himself—and Pwyll shall tie it shut and blow his horn as a signal. Thus will Gwawl be trapped and humiliated, and Rhiannon freed from her unwanted fate.
The Second Branch Opens: Bran and Matholwch
The first branch concludes with Pryderi’s naming and fostering, and the passage of years until Pwyll’s death, after which Pryderi rules the seven cantrevs of Dyved in happiness and love, later expanding his realm to include the three cantrevs of Ystrad Tywi and the four of Ceredigiawn. He chooses to marry Cigva, daughter of a noble house, and so the first branch closes.
The second branch begins with Bran the Blessed, son of Llyr, king of the island and bearer of the crown of Llyndein. One afternoon he sits on the rock above the sea at Harlech with his brother Manawyddan son of Llyr, his maternal brothers Nissyen and Evnissyen—sons of Eurosswydd through their mother Penardim, daughter of Beli. Nissyen is a maker of peace, reconciling kinsmen even in greatest wrath; Evnissyen stirs strife among brothers. As they sit, thirteen ships appear from the south of Ireland, swift with favorable wind. The king orders his men to learn the strangers’ intent. They see ships finely equipped with woven-silk banners; one ship overtakes the others and raises a shield as a sign of peace. The strangers land and greet Bran, revealing themselves as the host of Matholwch, king of Ireland, who comes as a suitor. He wishes to ally himself with Bran through marriage to Branwen daughter of Llyr, so that a bond may strengthen both the Island of the Strong and Ireland.
Bran welcomes him ashore and takes counsel with his nobles. They resolve to give Branwen to Matholwch. She is one of the three chief ladies of the island and the fairest maiden in the world. They appoint Aberffraw as the place where he shall lie with her. Matholwch and his host travel by ship; Bran and his host by land. At Aberffraw they feast in tents, for Bran cannot be contained in a house. Bran and Manawyddan sit on one side, Matholwch on the other with Branwen beside him. They eat and converse until sleep calls them, and that night Matholwch and Branwen lie together.
The Cauldron of Rebirth and Efnissyen’s Treachery
At a gathering the next day, the men of Ireland enter by one side and the men of the Island of the Strong by the other. The kingship is conferred and transferred to Matholwch’s sons. When peace is concluded, Bran has the boy—Branwen’s son—fetched, and he passes from Bran to Manawyddan. All who see him conceive love for him. Efnissyen calls the boy over with false warmth, asking whether his nephew, his sister’s son, will not come to him. Bran agrees, and the boy comes joyfully. In his heart, Efnissyen thinks that the kin do not expect the murder he is about to commit. He rises, seizes the boy by the feet, and before anyone can stop him, hurls him head-first into the fire.
When Branwen sees her son in the flames, she tries to throw herself after him, but Bran seizes her with one hand and his shield with the other. All rush through the house in terrible confusion, seeking their weapons. The Irish kindle a fire beneath the Cauldron of Rebirth and throw their dead into it; on the next day they emerge as mighty warriors as before, except that they cannot speak. When Efnissyen sees the men of the Island of the Strong lying dead with no rebirth destined for them, shame and horror seize him. He lies down among the corpses of the Irish, and two bare-footed Gwyddyl, taking him for one of their own, throw him into the cauldron. There he stretches out with such force that the cauldron bursts into four pieces and his breast also bursts. From this sacrifice comes the victory of the Island of the Strong—yet only seven men escape alive. Bran the Blessed is wounded in the foot by a poisoned lance-point.
The Head’s Journey and Branwen’s Lament
The seven survivors are Pryderi, Manawyddan, Gluneu Eil Taran, Talyessin, Ynawc Greadyen son of Muryel, and Heilyn son of Gwynn Hen. Bran commands them to cut off his head and carry it to the White Hill in London, burying it with the face toward France. The journey will be long. In Harlech they will sit seven years at a feast while Rhiannon’s birds sing for them, and all that time his head will be as pleasant company as when it sat upon his shoulders. In Gwales in Penvro they will spend eighty years, keeping the head unharmed until the moment they open the door facing Aber Genvelen toward Kernyw—but once opened, they cannot stay longer and must proceed to London to bury it. They cut off his head, carry it with them through the sea, and Branwen travels as the eighth among them.
They land at Aber Alaw in Talebolyon and rest. Branwen raises her eyes toward Ireland and toward the Island of the Strong, seeing all she can of both. “Woe, Son of God,” she cries, “cursed be my birth; two so fair islands were destroyed for my sake!” She sighs deeply, and her heart breaks. They make her a four-sided grave and bury her there on the bank of the Alaw.
The seven men turn toward Harlech, carrying the head with them. As they journey, they meet a host of men and women who bring dire news: Caswallawn son of Beli has conquered the Island of the Strong and is crowned king in London. Six of the seven men left to guard the island have been slain by Caswallawn, who wore a magic mantle rendering himself invisible; only the sword was seen striking them down. Caradawc son of Bran, whom Caswallawn spared because he was his nephew, saw his men fall without knowing who wielded the blade, and his heart broke from grief. Pendaran Dyved the Younger, who served the seven, has fled into the woods.
They reach Harlech and lay down to rest, providing themselves with food and drink in abundance. Then three birds arrive and sing them a song of such beauty that all they had ever heard before seemed without charm. The birds hover far above the sea, yet they see them as clearly as if they were close at hand. That feast lasts seven years.
The Hanging of the Mouse
Manawyddan stands alone on the hillside with his captive, preparing for an execution that will test not merely his will but his honor itself. He has endured seven years of desolation in this enchanted land, losing his fields to an invisible curse, and now holds the creature responsible—a single mouse, sluggish and caught red-handed among the wheat. He plants two forks on the highest point of the hill and begins his grim work. But the moment he raises the mouse to the gallows, the world intrudes with witnesses, each arriving to challenge his resolve.
A scholar in threadbare clothes emerges first, the first human Manawyddan has seen in seven years besides his three companions. The scholar observes the lord preparing to hang what appears to be a mouse and recoils at the sight. He offers a pound of alms to spare the creature, arguing that such an act befits no man of Manawyddan’s rank. Manawyddan refuses coldly; the mouse is a thief and must suffer a thief’s death. The scholar departs, troubled.
As Manawyddan places the crossbeam, a priest on a well-equipped horse arrives. He too sees the mouse and offers redemption through purchase—three pounds to release it. Again Manawyddan refuses, invoking God as witness that he will accept no price, only justice. The priest withdraws, shaking his head at such stubbornness over so worthless a creature.
Then comes a bishop with his full retinue and pack horses. The bishop pauses Manawyddan’s work and, after receiving a blessing, asks what he does. Manawyddan explains again: a thief caught stealing, now to be hanged. The bishop recognizes the mouse and, as a man of the Church, steps forward with an offer of redemption far greater than the others have made.
The Bishop’s Revelation
The bishop approaches with the authority of his office, and his words carry weight that neither scholar nor priest possessed. He offers not mere coins but a negotiation that cuts to the heart of the enchantment itself. He reveals that the mouse is no ordinary creature—it is his wife, transformed by magic. He offers Manawyddan a choice: release the mouse and receive compensation, or proceed with the hanging and face the consequences of executing a woman of noble birth, even in animal form.
Manawyddan, stunned by this revelation, demands to know the full truth. The bishop explains that the devastation of the fields, the curse upon the land, all of it stems from a magical vendetta. The bishop himself is Llwyd fab Cilcoed, a sorcerer whose wife and companions were transformed into mice as punishment for some prior wrong. The mouse Manawyddan holds is Llwyd’s wife, and her destruction would be an irreversible act against a woman of rank.
Understanding now that he holds not merely a thief but a transformed noblewoman, and that the entire enchantment has been orchestrated by this powerful sorcerer, Manawyddan negotiates. He demands that the curse be lifted entirely—that his land be restored, that his fields be freed from all magical harm, and that no further vengeance be visited upon him or his companions. Llwyd agrees to these terms. Manawyddan releases the mouse, the spell breaks, and the land returns to its natural state. The Third Branch concludes with Manawyddan’s vindication: through patience, courage, and ultimately wisdom in recognizing when to yield, he has broken the enchantment and restored his world.
The Birth of Llew Llaw Gyffes
The Fourth Branch opens with Math fab Mathonwys, a lord of power and magic, hearing the baying of hounds in his hall. He sends a man to investigate and learns that a stag, a hind, and her fawn have appeared in the forest. Math rises, takes his staff, and strikes the three beasts. With a word, he transforms them: the hind becomes a boar, the stag a sow, and both are cursed to bear the instincts of wild forest swine. They must return to him in a year with their offspring.
A year passes. The hounds bay again, and Math finds a boar, a sow, and a well-grown young one. He keeps the piglet, baptizes it, and names it Sychdwn. The parents he transforms once more—the boar becomes a wolf, the sow a she-wolf, and they are ordered to return in another year. When they appear again with a cub, Math keeps and baptizes the cub as Bleiddwn. He then strikes all three with his staff, restoring them to human form. They are revealed as the three sons of Gilfaethwy the Traitor, and their transformations have been their punishment. Math declares that they have suffered enough and orders them bathed, clothed, and restored to dignity. He then asks which maiden he should take as wife, and Gwydyon son of Dôn suggests Arianrod, daughter of Dôn and his own sister’s daughter.
When Arianrod is brought before Math, he asks if she is a virgin. She claims she knows no otherwise. Math takes his magic staff and commands her to step over it. As she does, a fair-haired, strong child falls from her. As she flees toward the door in shame, a second small creature falls. Gwydyon seizes it swiftly, wraps it in silk, and hides it in a chest at the foot of his bed. Math baptizes the fair-haired child Dylan. Immediately after baptism, Dylan goes to the sea and takes on the nature of water itself, becoming as swift a swimmer as any fish. He is called Dylan ail Don, but his fate is sealed: a wave will break beneath him, and his death will come by the hand of Gofannon his uncle—one of the three fateful blows of the island.
The Hidden Child and His Naming
From the chest comes crying. Gwydyon opens it to find a small boy thrashing against the silk mantle. He takes the child to a woman who nurses him for a year, and by year’s end the boy is as large as a two-year-old. In the second year he can walk to court alone. By his fourth year he appears as an eight-year-old, his growth unnaturally swift. Gwydyon watches over him with deep affection, and the boy grows devoted to his guardian.
One day Gwydyon walks out and the boy follows him to Arianrod’s castle. Arianrod welcomes Gwydyon but asks who the boy is. Gwydyon tells her plainly: the boy is her son. She reproaches him bitterly for shaming her and prolonging her dishonor through his deception. Gwydyon replies that if bearing and rearing such a boy is her greatest shame, she has little to complain of. She demands the boy’s name, but Gwydyon says he has none. Arianrod lays a destiny upon the child: he shall have no name until she gives him one. Gwydyon swears in anger that she is a worthless woman, that the boy shall have a name despite her, and that she will never recover what she has lost—the name Virgin. He leaves in fury for Caer Dathyl.
The next day Gwydyon takes the boy to the seashore near Aber Menai. There, seeing seaweed and sea foam, he works magic, conjuring a boat and transforming the seaweed into Cordovan leather of many colors. They sail to the entrance of Arianrod’s castle. Gwydyon begins crafting and sewing shoes with such skill that word reaches Arianrod. She sends her foot measurements and requests shoes. Gwydyon deliberately makes them too large, then too small, refusing to continue until he sees her foot himself. When she comes to the boat, Gwydyon is cutting leather and the boy is sewing. A wren lands on the deck, and the boy shoots it between sinew and bone in the leg with perfect accuracy. Arianrod laughs and says the little lion has struck with a sure hand. In that moment, Gwydyon declares the boy’s name: Llew Llaw Gyffes—the Lion with the Sure Hand. All the leather reverts to seaweed and foam.
Armor and Destiny
Arianrod, enraged at being outwitted, lays another destiny: the boy shall bear no armor until she clothes him in it herself. Gwydyon swears he shall have armor despite her. They go to Dinas Dinlleu, where the boy is reared until he can manage every horse and is perfect in features, growth, and strength. Seeing him ashamed at lacking weapons and horse, Gwydyon proposes a journey. They ride to Brynn Elrpen, then to Cevyn Clydno, and finally to Arianrod’s castle in disguise as two young men, Gwydyon bearing a sterner face. Announced as bards from Morgannwe, they are welcomed. After the meal, Arianrod speaks with Gwydyon of tales and fables, and he proves himself an excellent storyteller. At night Gwydyon rises and works his magic, conjuring arms and armor that appear as if sent by Arianrod herself, fulfilling his oath and breaking her destiny. The Fourth Branch continues, and with it the entanglement of magic, destiny, and the struggle between will and fate that defines the world of the Mabinogi.
Characters
The tales move through a succession of figures whose names often betray their divine origins, even as their deeds have been drawn into a more human, magical world. Pwyll, prince of Dyfed, encounters the otherworldly Rhiannon and wins her through cunning and patience, fathering Pryderi, who becomes the thread connecting all four branches—though never quite the central hero, always standing in the shadow of greater powers. Bran the Blessed, king of the Island of the Strong, is a figure of such magnitude that no ordinary house can contain him; his brother Manawyddan son of Llyr carries forward the action after Bran’s sacrifice, enduring years of enchantment and humiliation before reclaiming his land. Arianrod, daughter of Dôn, embodies the capricious power of the old gods—a woman who curses her own son Llew Llaw Gyffes with impossible destinies, only to have them thwarted by her uncle Gwydyon’s superior magic. These are not characters bound by the logic of the human world alone; they move in a realm where transformation, enchantment, and the will of the supernatural are as real as hunger or love.
Themes
The four branches form no unified epic narrative in the classical sense. Rather, they are a cyclic arrangement of legends drawn from a common mythical body, reworked by medieval storytellers who no longer possessed the original sacred meaning but recognized its power. What emerges is a meditation on the nature of loss and recovery—of kingdoms enchanted and disenchanted, of sons separated from fathers and restored through recognition, of the old divine order persisting in fragmented form within a Christian world. Magic here is not exotic spectacle but the ordinary grammar of a world where the boundary between human and animal, living and dead, visible and invisible remains permeable. The tales also explore the tension between fate and will: characters are bound by curses and destinies laid upon them, yet they find ways to circumvent or fulfill them through cleverness, sacrifice, and the exercise of power. There is a deep melancholy running through these stories—a sense that something ancient and magnificent is passing away, preserved only in the memory-work of bards who half understand what they are preserving.
Why It Endures
The Mabinogi stands as one of the few surviving documents of early Celtic narrative art, a window into a literary and mythological world that would otherwise be lost. For centuries these tales were known only through Guest’s nineteenth-century translation; this German edition, drawing on the medieval manuscripts themselves, restores them to readers as a work of genuine imaginative power—not as archaeological curiosity, but as living story. The four branches have been compared to the Norse Eddas compiled by Snorri Sturluson: both are the work of learned men tasked with preserving the mythical inheritance of their people, both stand at the threshold between oral tradition and written literature, both capture a world in which the sacred and the mundane are not yet fully separated. Readers return to the Mabinogi because it offers something modern literature rarely provides—a narrative space where magic is neither explained nor apologized for, where the past is not safely contained in history but erupts into the present, and where the deepest human longings—for recognition, for home, for the recovery of what has been lost—are enacted in a language that feels both strange and strangely familiar.
