A Welsh Myth Concordance

by Mike Nichols


"Books are words of wisdom spoken by the dead to the living."
--Welsh proverb

The following concordance is based on the four branches of the Welsh "Mabinogi", as retold in the four books by Evangeline Walton: "Prince of Annwn", "The Children of Llyr", "The Song of Rhiannon", and "The Island of the Mighty". Unfortunately, the Ballantine editions of these books, which were used in preparing this concordance, are long since out of print. Although later editions have been published, they do not maintain the same pagenation as the Ballantine originals. Therefore, I have not included page number references in this edition of the concordance, although I reserve the right to add them to future editions, if standard editions of the books are published. Walton's original publishing dates span a range from 1936 to 1974.

The Evangeline Walton books were selected as the primary texts for this concordance because they, like Lady Gregory's treatment of the Irish myths, represent the most comprehensive synthesis of variant sources (both published and oral) ever attempted as a continuous narrative of Welsh mythology. Although Walton does not list her primary sources, an educated guess would be that the Lady Charlotte Guest edition formed the basis of the works, with supplimentary material drawn from various scholarly sources (most notably on the Welsh Triads).


Aber Alaw - in Talebolyon. Where the Seven Who Returned from Ireland landed, on the holy Isle of Anglesey. Here, Branwen died.

Aberffraw - Branwen and Matholuch passed their wedding night here.

The battle of Cad Goddeu followed, in which Gwydion assisted Amaethon by turning trees into warriors.

Amergin - Ireland's High Druid, oldest and wisest of Ireland's Old Tribes. Had he still lived, the great war between Ireland and the Island of the Mighty might have been prevented.

Annwn - Arawn's realm. The Abyss. The Underworld in which all things first took shape. World of Middle Light. It is the first world above our own. Annwn was challenged by Havgan, but Arawn, with the help of Pwyll, defeated him. Later, Amaethon raided Annwn for the secrets of agriculture and husbandry, stealing a bitch, a hind, and a lapwing.

Arawn - King of Annwn. He changes places with Pwyll of Dyved for a year and a day in order that Pwyll may help him defeat Havgan Summer-White, ruler of the Dead of the Eastern World. Arawn is the Grey Man of Earth, a Death Lord who kills in order to bring forth new life. He is first-born and husband to Modron, the Goddess behind all the Gods.

Blodeuwedd - "Flower-like." She was fashioned from flowers by Gwydion and Math to be Llew's bride, since he could not have a mortal woman because of the destiny laid on him by Arianrhod. However, Blodeuwedd learns the secret of Llew's mortality and betrays him to her lover, Goronwy Pevr. For this, Gwydion turns her into an owl - "flower face." She may be a Dawn Goddess transformed into a Dusk Goddess.

Boyne - Bran's host beached near the mouth of this river on reaching Ireland, and in its waters, Bran bathed. It was named for an Ancient Goddess, Mother of Angus of the Birds. The river Boyne flows past Tara and past the Brug na Boinne.

Bran the Blessed - first born of Llyr and Penardim; nephew and successor to Beli of the Deep as High King of the Island of the Mighty. He led the hosts of the Island of the Mighty against King Matholuch of Ireland to avenge the wrongs committed to Branwen, Bran's sister and Matholuch's wife. Being of unusually large proportions, Bran was forced to wade through the Sinking lands to reach Ireland. On returning, he was ambushed at Morddwydtyllyon, and received a fatal wound from Matoluch. Bran was called "ancestor to many saints."

Branwen - "the White Breast." Daugher of Llyr and Penardim, princess of the Island of the Mighty. Bran consents to her marriage to Matholuch, High King of Ireland, and to her leaving the Island of the Mighty. In Ireland, she is mistreated and dishonored but she manages to send word to Bran, by means of a starling. This begins the great war between Ireland and the Island of the Mighty. Her son, Gwern, is killed by Evnissyen, and she herself dies before returning to the Island of the Mighty.

Brenhines-y-nef - another title of Modron.

Bright World - the realm of Faery. Rhiannon was a princess here, where Gwawl the Bright asked her father, King Heveydd the Ancient, for her hand in marriage. However, Pwyll succeeds in bringing her to Dyved to become his own bride. And though Gwawl had sworn to take no vengeance for this, the Grey Man of the Bright World, Llwyd ap Kilcoed, blasts Dyved for seven years. Gorsedd Arberth was a door to the Bright World in Dyved.

Cad Goddeu - a magical battle in which Gwydion turned trees to men to aid his brother Amaethon, who had stolen the secrets of agriculture and husbandry (a bitch, a hind, and a lapwing) from Arawn, King of Annwn. The great champion from out of Faery, Bran of the Glittering Branches, fought in that battle, and Gwydion won the battle by guessing his name.

Caer Arianrhod - in the sea. Also called the Castle of the Silver Wheel. It rose from a tiny islet in the sea, bound on all sides by water. Here, Arianrhod and her three sisters were priestesses to a sacred well. Caer Arianrhod was destroyed when Arianrhod opened the Casket of Ancient Spells and invoked the powers of the well. Her three sisters managed to escape the final cataclysm.

Calch Llassar - a blue enamel created by Llassar, and used by Manawyddan.

Casket of Ancient Spells - saved from the Sinking Lands and brought to the Island of the Mighty. Although Math would have returned them to the Lost Lands of the West, Don preserved them, telling only Arianrhod of their hiding place. Its power contributed to the destruction of Caer Arianrhod.

Castle of the Silver Wheel - Caer Arianrhod (q.v.).

Caswallawn - variant of Caswallon.

Caswallon - the Cunning. Second son of Beli. During the war with Ireland, he stayed behind in the Island of the Mighty and, aided by magic of invisibility, slew six of the Seven Chiefs. Caradoc, their chief, died of his own love for the men who were slain. Caswallon then seized the throne of High King while Bran, the true High King, was in Ireland. Bran never returned and Manawyddan, the rightful heir, chose not to dispute Caswallon's claim to the throne. Caswallon is named one of the Three Gold Shoemakers for his disguise when he went to Gaul to save Flur from being abducted by the Imperial Caesar and King Mwrchan the Thief.

Cauldron of Rebirth - belongs to Arawn, in Annwn, though Llassar and Kymideu Kymeinvoll managed to steal a shadow of it, which they brought first to Ireland and then to the Island of the Mighty where they gave it to Bran. He gave it to Matholuch as face-price for Evnissyen's offence to the Irish. On earth, the Cauldron had the power to re-animate corpses and send them forth to kill. Matholuch unleashed this weapoin against Bran's forces in the great war between Ireland and the Island of the Mighty. In the end, it is destroyed by Evnissyen.

Dyved - Pwyll's Kingdom; and later, Pryderi's. It consists of one- and-twenty cantrevs in the South, though for a time the Seven Cantrevs of Seissyllwch were independant.

There, in Llew's absence, he became her lover and together they plotted to kill Llew. Blodeuwedd tricked Llew into telling her of the one way in which he might be killed. Goronwy used his knowledge to slay Llew, but Gwydion restored Llew and later Llew kills Goronwy.
