Welsh mythology

Welsh mythology, also called Y Chwedlau meaning 'the legends', is a rich collection of stories and traditions from Wales. These tales come from both the people of Wales and the ancient Celtic Britons who lived there long ago. Like many oral societies, the stories of Celtic mythology and history were shared by special storytellers known as druids, called derwyddon in Welsh.

A leading figure in Welsh mythology, Ceridwen featuring in works by medieval bards, Victorian writers and modern artists. She is regarded as the goddess of rebirth, transformation, and inspiration by modern pagans.

Over time, these oral stories changed because of outside influences and invasions. Many of these changed myths and histories are saved in mediaeval Welsh manuscripts. Important books include the Red Book of Hergest, the White Book of Rhydderch, the Book of Aneirin, and the Book of Taliesin. Other works related to Welsh myths are the ninth-century Latin book Historia Brittonum and a 12th-century Latin chronicle called Historia Regum Britanniae by Geoffrey of Monmouth. Later, Welsh folklore was collected in books such as The Welsh Fairy Book by William Jenkyn Thomas in 1908.

Cosmogony and creation

The Welsh people had many stories about how the world began. These stories were not written down. Special storytellers called druids told them aloud, passing them from one person to another. Because they were not written, many of these stories have been lost or changed.

We can learn about these old beliefs by looking at the names of gods and goddesses and old tales that survived. For example, the goddess Dôn may have been called “the earth” in an ancient language. This shows she was an important mother figure. Some stories tell of heroes and goddesses coming together and having children. The Welsh believed in different realms, like the world of humans called Elfydd and another world called Annwn, where gods and spirits lived. This other world may have been thought of as deep parts of nature, like forests or lakes.

Legends

The Four Branches of the Mabinogi

Main article: Four Branches of the Mabinogi

Four important stories in Welsh mythology are known as the Four Branches of the Mabinogi. These tales are about the adventures of ancient British leaders who become kings and heroes. The main character in all these stories is Pryderi fab Pwyll, the king of Dyfed. He is born in the first story, dies in the last, and is linked to the Celtic god Maponos. Other important characters include Pryderi's mother Rhiannon and her later husband, Manawydan. Manawydan is also connected to Brân the Blessed, Branwen, and Efnysien.

Pwyll, Prince of Dyfed

The first story explains how Pwyll, prince of Dyfed, spends a year with Arawn, the ruler of Annwn, the magical otherworld. Pwyll defeats Arawn's enemy Hafgan and returns to find Rhiannon, a beautiful lady whose horse he could not catch. He wins her love, though she was promised to another man, and they have a son who seems to disappear at birth. Rhiannon is punished, but the child is found and returned to them, and he grows up to be Pryderi.

Branwen ferch Llŷr

The Two Kings (sculptor Ivor Roberts-Jones, 1984) near Harlech Castle, Wales. Brân the Blessed carries the body of his nephew Gwern.

In the second story, Branwen, sister of Brân the Blessed, marries Matholwch, king of Ireland. Trouble starts when Branwen's brother Efnysien ruins Matholwch's horses, so Brân gives new horses and treasure as a peace offering. Matholwch mistreats Branwen, but she sends a message to her brother Brân, who gathers an army. A big battle happens, and only a few men survive, including Pryderi and Manawydan. Brân is badly hurt, so he asks to have his head brought back to Britain. Branwen dies of sadness at home, and five women survive to repopulate Ireland.

Manawydan fab Llŷr

Pryderi and Manawydan return to Dyfed, where Pryderi marries Cigfa and Manawydan marries Rhiannon. A mist covers the land, leaving it empty. They try hunting, then move to England and make saddles, shields, and shoes, but each time they are driven away by local workers. Back in Dyfed, they become hunters again. A white boar leads them to a strange castle where Pryderi and Rhiannon disappear. Later, Manawydan and Cigfa return to England but are driven away again. They plant three fields of wheat in Dyfed, but the crops are destroyed. Manawydan catches the leader of the mice destroying the last field and demands the return of Pryderi and Rhiannon and the end of the magic mist. The request is granted, and the land returns to normal.

Math fab Mathonwy

While Pryderi rules Dyfed, Gwynedd in north Wales is ruled by Math, son of Mathonwy. Math's feet must rest on a virgin's lap unless he is at war. His nephew Gilfaethwy loves Goewin, Math's current footholder, and his brother Gwydion tricks Math into going to war so Gilfaethwy can be with her. Gwydion kills Pryderi, and Gilfaethwy harms Goewin. Math marries Goewin to protect her and banishes Gwydion and Gilfaethwy, turning them into animals for three years before returning them to human form. Math then needs a new footholder and considers his sister, Arianrhod. When Math tests Arianrhod, she gives birth to two sons. One son, Dylan, goes to the sea right away. The other is raised by Gwydion, but Arianrhod refuses to name him or give him arms until Gwydion tricks her. She also says he will never have a wife, so Gwydion and Math create a wife for him from flowers named Blodeuwedd. Blodeuwedd falls in love with another man, Gronw Pebr, and they plan to harm Lleu. Lleu escapes and turns Blodeuwedd into an owl. Gronw tries to harm Lleu but is defeated.

Cad Goddeu

A big battle called the Battle of the Trees happened between the sons of Dôn and the forces of Annwn, the Welsh otherworld. Amaethon, one of Dôn's sons, takes a white roebuck and a whelp from Arawn, starting a great battle. Gwydion fights with his brother and Lleu, using magic to make trees and plants come to life as warriors. A warrior for Arawn can only be defeated if his name is known, and Gwydion figures out his name by looking at symbols on his shield.

Hanes Taliesin

Guest included Hanes Taliesin in her translation of the Mabinogion, though it is not found in old Welsh books and is considered a later story. Still, some parts of it are older. In the story, Taliesin starts as Gwion Bach, a servant to an enchantress named Ceridwen. Ceridwen wants to make a magic potion to help her ugly son, and Gwion stirs the potion. Three drops spill on him, giving him wisdom. He runs from Ceridwen, who chases him in different animal forms. Gwion turns into a grain of corn, but Ceridwen eats him as a hen. She becomes pregnant and gives birth to a child she throws into the ocean. The child is found and named Taliesin, meaning "radiant brow." He grows up to be a great poet.

The Spoils of Annwfn is an old poem found in the Book of Taliesin. It describes an expedition led by King Arthur into the Otherworld to get a magical cauldron. Arthur and his men travel to Annwfn, but only seven return. The poem talks about a prisoner in chains and a cauldron that will not cook food for cowards. The reason for the tragedy is not clearly explained, and the poem ends with criticism of monks and others who lack knowledge.

King Arthur

Stories about King Arthur became popular all over Europe, but Wales has the earliest tales about him. Before Arthur became a well-known hero, stories about him were mostly told in Wales, as well as in Cornwall and Brittany. These early stories are split into two groups: those before the writings of Geoffrey of Monmouth and those inspired by him.

Pre-Galfridian texts

Some of the oldest mentions of Arthur include:

Y Gododdin: A poem that mentions a warrior who "was no Arthur."
Poems by Taliesin: These include Kadeir Teyrnon, which calls Arthur "the Blessed," and Preiddeu Annwn, which tells of Arthur's journey to another world.
From The Black Book of Carmarthen: Pa gur yv y porthaur?, a dialogue where Arthur describes his adventures.
The Welsh prose tale Culhwch and Olwen: This story, written around 1100, is part of the Mabinogion collection and features Arthur.
The Welsh Triads: Short summaries of Welsh traditions where Arthur's court represents all of Britain.
Historia Britonum: This book lists twelve battles led by Arthur, calling him a war leader.
Annales Cambriae: This history book mentions Arthur in several events, including battles and a story about Merlin.

Geoffrey of Monmouth

Geoffrey of Monmouth wrote several important works about Arthur:

Prophetiae Merlini: Geoffrey wrote stories about Merlin, presenting them as real prophecies.
Historia Regum Britanniae: This book tells how Arthur became king after the Romans left Britain, fought off invaders, and ruled with peace and prosperity until his final battle.
Vita Merlini: A poem by Geoffrey that mixes old Welsh stories about Merlin with other traditions.

Welsh Arthurian romance

Wales also created its own versions of Arthurian tales, which are part of the Mabinogion collection. These include stories like Owain, or The Lady of the Fountain, Peredur Son of Efrawg, and Gereint Son of Erbin. They were likely influenced by the works of Chrétien de Troyes.

Folklore

Mythical creatures

Welsh folklore has many interesting mythical creatures. Some of these are:

Adar Llwch Gwin, giant birds that can understand human speech.
Afanc, a monster that lives in lakes, though the exact lake changes in different stories.
Bendith y Mamau, another name for the Tylwyth Teg or Welsh fairy folk, meaning Blessings of the Mothers.
Brenin Llwyd, a silent, ghostly figure found in mountains. This figure is often seen in mist and is said to wander lonely places.
Bwbach (plural Bwbachod), a friendly house spirit similar to a brownie or hobgoblin. They like to help around the house but enjoy playful tricks. They appreciate a nightly bowl of cream and don’t like clergymen or teetotalers, whom they tease.
Bwca, another brownie that does housework in exchange for bread and milk.
Ceffyl Dŵr, a water horse much like the Kelpie.
Cewri (Giants), such as Ysbaddaden Bencawr from Culhwch and Olwen.
Coblynau, little people or mine spirits similar to the Knocker.
Cŵn Annwn, special hunting dogs from another world.
Y Diawl (The Devil), who is said to have built many bridges in Wales (including Devil's Bridge, Ceredigion).
Dreigiau (Dragons), with the most famous being Y Ddraig Goch.
Y Dyn Hysbys (The Wise Man), or wizard.
Gwiddonod (Witches), older women who could cast spells, ride on broomsticks, tell the future, and heal or cause sickness.

Ysbrydion (spirits), more likely to appear to humans on special spirit nights, such as Calan Gaeaf and Calan Mai.

Folk narrative

Welsh folklore has many folk tales, legends, traditions, and stories. The cyfarwyddiaid (singular: cyfarwydd, “storyteller”), were special members of the bardic order in Wales.

The cyfarwyddiaid were educated and had important duties. They were court officials trained in their art and often worked closely with their lords. Their jobs included praising, celebrating, and mourning their lords. They preserved and shared traditional stories, acted as historians, and protected the family histories of powerful families.

These tales were shared as proverbs, songs, and spoken stories. Historical and imaginative stories were told together, helping to teach culture and history through poetry.

Medieval Welsh storytelling followed certain rules and themes. It used poetic patterns, old verses, and knowledge of history to create well-crafted stories about the past. Stories were often told in short parts, making them easy to remember from oral tradition. Welsh tales were similar to Irish literature, both aiming to inform about the past rather than criticize ancestors.

Folk tales and legends were also passed down by everyday people. Storytelling happened in many ways: through chatter, games, dancing, riddles, tongue-twisters, nursery rhymes, harp songs, folk songs, and ballads. Common times for storytelling were nosweithiau llawen (or “merry evenings,” like a céilidh), nosweithiau gwau (“knitting nights”), and Calan Gaeaf (Winter’s Eve).

Tales about animals with human characteristics

One famous group of stories is about the “Oldest Animals,” where a character meets different animals until finding the oldest. Culhwch and Olwen mentions the Blackbird of Cilgwri, the Stag of Rhedynfre, the Owl of Cwm Cowlyd, the Eagle of Gwernabwy, and the Salmon of Llyn Llyw.

Formula tales

These include cumulative tales and stories without end.

Humour about actual persons or types

This includes White Lie Tales, which are clearly made-up and funny.

(Pseudo-)histories of notable figures

Arthur (see separate section above)
Twm Siôn Cati, often called the Welsh Robin Hood
The Lives of Saints, originally written in Latin.

Local legends of historical or pseudo-historical figures

This includes Gwylliaid Cochion Mawddwy, a group of robbers who lived in Merioneth in the 16th century.

Another well-known legend is about Gelert, the namesake of the town of Beddgelert. The story teaches a lesson about acting too quickly.

Place-name or topography tales

These tales explain how places got their names.

Collectors of folk tales

Poet-scholars: Rhys Meurig (Rice Merrick), George Owen of Henllys.

Travelogue

Gerald of Wales wrote about Welsh mythology and folklore in his books Itinerarium Cambriae from 1191 and Descriptio Cambriae from 1194. His books tell many stories and traditions from Wales.

National histories

Some old books tell stories about where the Welsh people came from. These books are called histories, but they also share myths that many Welsh people believe.

The books include Historia Britonum, Annales Cambriae, and the works of Geoffrey of Monmouth.

Legacy of Welsh mythology in English literature

Welsh myths have inspired many stories in English books. Tales about King Arthur are very popular. Writers like William Morris used stories from a collection called The Mabinogion in his plays. Another writer, John Cowper Powys, used these myths in his novels Owen Glendower and Porius.

Characters like Taliesin, Blodeuwedd, and Myrddin Wyllt appear in books such as Thomas Love Peacock's The Misfortunes of Elphin and Porius: A Romance of the Dark Ages by John Cowper Powys. There are also stories about a character named Madoc.
