The Mabinogion Vol. 3

In Short

This volume brings together the foundational texts of early Welsh myth, capturing the four core branches of the Mabinogion alongside legendary tales of prophecy and ancient kings. Rooted in a deeply pagan landscape unaffected by later chivalric traditions, the stories trace intergenerational feuds, magical entrapments, and tragic conflicts across Britain and Ireland. From the supernatural courts of Dyved to the tragic siege of Ireland and the wondrous birth of the bard Taliesin, these prose sagas have endured for centuries due to their eerie elegance, psychological sharpness, and hauntingly vivid mythic imagination.

The Story

The volume opens in Dyved, where Prince Pwyll encounters Arawn, king of the underworld domain of Annwvyn. The two exchange realms and appearances for a year, forming an enduring alliance. Later, sitting atop a magical mound, Pwyll meets Lady Rhiannon, a figure of radiant mystery riding a unhurried white horse. Through cleverness, Rhiannon helps Pwyll outwit her unwanted suitor, Gwawl, trapping him in a magical bag until he renounces his claim. Their union produces a son, Pryderi, who vanishes on the night of his birth. Rhiannon is falsely accused of infanticide and condemned to sit at the palace gate as a beast of burden, carrying guests inside. Years later, a noble lord named Teirnyon recognizes the missing child’s likeness to Pwyll and restores the boy to his rightful parents, lifting Rhiannon's public humiliation.

Tragedy takes center stage in the tale of Branwen, sister to the giant king Bendigeid Vran. When she is married to Matholwch, King of Ireland, an insult by her half-brother leads to revenge: Branwen is banished to the palace kitchens and beaten daily. Upon discovering her plight via a message carried by a trained starling, Bendigeid Vran leads a massive fleet across the sea to rescue her, wading through the water himself because no ship can hold him. The war in Ireland turns catastrophic; Bendigeid Vran is mortally wounded by a poisoned dart and instructs his seven surviving men to cut off his head. For eighty years, his men feast in a magical palace where the preserved head converse with them, insulating them from grief until a forbidden door is opened, bringing all their past sorrows flooding back.

In the aftermath, Pryderi and Manawyddan return to Dyved, only to find a supernatural mist consume the land, wiping away all livestock and inhabitants. Forced to support themselves through craftsmanship and hunting, they encounter a mysterious white boar that lures Pryderi into an enchanted castle, trapping him alongside a golden bowl. Manawyddan uses cunning to free his stepson: catching a mouse stealing his wheat, he insists on hanging it as a thief, ignoring the pleas of priests and bishops. The mouse is revealed to be the shape-shifted wife of Llwyd, a sorcerer seeking revenge; Manawyddan refuses to spare her life until the land's curse is lifted and his family is returned.

Further tales explore the wild sorcery of Gwynedd, where Gwydion uses illusion to trick his sister Arianrod into named and arming her denied son, Llew Llaw Gyffes. To circumvent a curse preventing Llew from taking a mortal bride, Gwydion weaves him a wife out of flowers named Blodeuwedd. However, Blodeuwedd conspires with a lover to murder Llew via an elaborate, highly specific death ritual. Llew is struck down but escapes in the form of an eagle, later recovered and restored by Gwydion, who turns the unfaithful wife into an owl. Finally, the collection concludes with the tale of Taliesin, a child born of shape-shifting magical pursuits who is cast into the sea, discovered in a fishing weir, and grows into a legendary bard capable of freeing his patron from prison through sheer poetic power.

How It Unfolds

The pact with Annwvyn Pwyll exchanges identities and kingdoms with the underworld ruler Arawn for a full year, defeating Arawn's rival in single combat while maintaining strict purity toward the queen. Upon returning to his own body, Pwyll secures an unbreakable bond between the two realms.

The wonder on the mound Sitting on the enchanted mound of Gorsedd Arberth, Pwyll witnesses the golden-clad Rhiannon riding past on a white horse that no pursuer can catch regardless of speed. After he speaks to her directly, she agrees to wed him and aids him in outwitting her persistent former suitor.

The giant crosses the sea Following the terrible mistreatment of his sister Branwen in Ireland, Bendigeid Vran wades across the Irish Channel alongside his navy. When the Irish destroy the river bridge to halt the invasion, the giant king lays his own massive body across the water to act as a bridge for his host.

The head at the banquet After a devastating battle leaves Ireland barren and Britain ruined, seven survivors carry the severed, living head of Bendigeid Vran to a feast hall in Harlech. They live in absolute joy for eighty years until a door looking toward Cornwall is opened, instantly restoring all their lost memories and grief.

The thief in the wheat Finding Dyved laid waste by sorcery and his family ensnared by a golden bowl, Manawyddan plants three crops of wheat, only to catch a mouse eating the harvest. He builds a tiny gallows on a hill to execute the creature, forcing a disguised sorcerer to surrender his spells to save his transformed wife.

The bride made of blossoms Using the flowers of the oak, broom, and meadow-sweet, the magicians Math and Gwydion conjure a woman of exceptional beauty for Llew Llaw Gyffes. Their creation, Blodeuwedd, ultimately betrays Llew by extracting the secret of his vulnerable death condition and plotting his murder.

The bard in the weir After being swallowed as a grain of wheat and born of a shape-shifting witch, the infant Taliesin is cast adrift in a leather bag. Pulled from a fishing weir on May Eve by the unlucky Elphin, the child instantly speaks in complex verse, promising his savior immense fortune and glory.

What It's Really About

Beneath its fantastic shape-shifting, magical cauldrons, and terrifying curses, this text explores the volatile nature of sovereign obligation, honor, and the binding force of the spoken word. The plot turns constantly on pledges that cannot be broken once made, showing how a single reckless promise or unprovoked insult can trigger nationwide ruin. It examines the deep grief of loss and the inescapable weight of memory—symbolized vividly by the long banquet where time stands still until the forbidden door is unsealed. At its core, the text captures an ancient worldview where the boundary between the mortal realm and the otherworldly realm is razor-thin, and where quiet patience and clever wit prove far more effective than brute strength when facing the unknown.

Why Read It Today

This collection offers direct access to the raw, untamed roots of British mythology, untouched by the moralizing tendencies of later chivalric romance. Readers accustomed to modern fantasy will be struck by the sheer wildness of the narrative logic—where a woman can be crafted entirely from forest flowers, a severed head keeps pleasant company for decades, and shape-shifting chases occur across land, sea, and sky. The prose moves with a crisp, cadence that feels both archaic and strikingly direct.

Reading this translation requires adjusting to a cyclical, episodic narrative style that prioritizes mythic resonance over modern character psychology. The names are unfamiliar, the geographical shifts are frequent, and the period attitudes toward justice and retribution can be harsh. Yet what remains long after finishing is the haunting atmosphere: the quiet terror of a sudden mist wiping out an entire kingdom, the tragic beauty of Branwen’s bird messenger, and the fierce, enduring power of the spoken word. It is an essential encounter for anyone fascinated by the origins of storytelling.
