In Irish mythology, Nuada or Nuadu, known by the epithet Airgetlám, was the first king of the Tuatha Dé Danann. He is also called Nechtan, Nuadu Necht and Elcmar, and is the husband of Boann. He is mostly known from the tale in which he loses his arm or hand in battle, and thus his kingship, but regains it after being magically healed by Dian Cécht. Nuada is thought to have been a god and is related to the British and Gaulish god Nodens, who is associated with hunting and fishing. His Welsh equivalent is Nudd or Lludd Llaw Eraint.
Gwyn ap Nudd is a Welsh mythological figure, the king of the Tylwyth Teg or "fair folk" and ruler of the Welsh Otherworld, Annwn, and whose name means “Gwyn, son of Nudd”. Described later on as a great warrior with a "blackened face", Gwyn is intimately associated with the otherworld in medieval Welsh literature, and is associated with the international tradition of the Wild Hunt.
Creiddylad, daughter of King Lludd, is a minor character in the early medieval Welsh Arthurian tale Culhwch ac Olwen.
Hu Gadarn is a supposed Welsh legendary figure who appears in several of a series of Welsh Triads produced by the Welsh antiquarian and literary forger Iolo Morganwg. These triads, which Iolo put forth as medieval works, present Hu as a culture hero of the ancient Britons who introduced ploughing. However, it is now known that the triads, like all of the so-called "Third Series" of triads, were fabricated by Iolo himself. The name "Hu Gadarn" earlier appeared in a Welsh translation of a French romance about Charlemagne. Still, Iolo's version of Hu Gadarn was taken up in the 20th century by the poet Robert Graves, who associated him with other Celtic figures; since then he has been popular among neopagans.
The Mabinogion are the earliest Welsh prose stories, and belong to the Matter of Britain. The stories were compiled in Middle Welsh in the 12th–13th centuries from earlier oral traditions. There are two main source manuscripts, created c. 1350–1410, as well as a few earlier fragments. The title covers a collection of eleven prose stories of widely different types, offering drama, philosophy, romance, tragedy, fantasy and humour, and created by various narrators over time. There is a classic hero quest, "Culhwch and Olwen"; a historic legend in "Lludd and Llefelys", complete with glimpses of a far off age; and other tales portray a very different King Arthur from the later popular versions. The highly sophisticated complexity of the Four Branches of the Mabinogi defies categorisation. The stories are so diverse that it has been argued that they are not even a true collection.
Ys, also spelled Is or Kêr-Is in Breton, and Ville d'Ys in French, is a mythical city on the coast of Brittany that was swallowed up by the ocean. Most versions of the legend place the city in the Baie de Douarnenez.
Lud, according to Geoffrey of Monmouth's legendary History of the Kings of Britain and related medieval texts, was a king of Britain in pre-Roman times who founded London and was buried at Ludgate. He was the eldest son of Geoffrey's King Heli, and succeeded his father to the throne. He was succeeded, in turn, by his brother Caswallon. Lud may be connected with the Welsh mythological figure Lludd Llaw Eraint, earlier Nudd Llaw Eraint, cognate with the Irish Nuada Airgetlám, a king of the Tuatha Dé Danann, and the Brittonic god Nodens. However, he was a separate figure in Welsh tradition and is usually treated as such.
Beli Mawr was an ancestor figure in Middle Welsh literature and genealogies. He is the father of Cassivellaunus, Arianrhod, Lludd Llaw Eraint, Llefelys, and Afallach. In certain medieval genealogies he is listed as the son or husband of Anna, cousin of Mary, mother of Jesus. According to the Welsh Triads, Beli and Dôn were the parents of Arianrhod, but the mother of Beli's other children—and the father of Dôn's other children—is not mentioned in the medieval Welsh literature. Several royal lines in medieval Wales traced their ancestry to Beli. The Mabinogi names Penarddun as a daughter of Beli Mawr, but the genealogy is confused; it is possible she was meant to be his sister rather than daughter.
Cassivellaunus was a historical British military leader who led the defence against Julius Caesar's second expedition to Britain in 54 BC. He led an alliance of tribes against Roman forces, but eventually surrendered after his location was revealed to Julius Caesar by defeated Britons.
Welsh mythology consists of both folk traditions developed in Wales, and traditions developed by the Celtic Britons elsewhere before the end of the first millennium. As in most of the predominantly oral societies Celtic mythology and history were recorded orally by specialists such as druids. This oral record has been lost or altered as a result of outside contact and invasion over the years. Much of this altered mythology and history is preserved in medieval Welsh manuscripts, which include the Red Book of Hergest, the White Book of Rhydderch, the Book of Aneirin and the Book of Taliesin. Other works connected to Welsh mythology include the ninth-century Latin historical compilation Historia Brittonum and Geoffrey of Monmouth's twelfth-century Latin chronicle Historia Regum Britanniae, as well as later folklore, such as the materials collected in The Welsh Fairy Book by William Jenkyn Thomas (1908).
Edward Williams, better known by his bardic name Iolo Morganwg, was a Welsh antiquarian, poet and collector. He was seen as an expert collector of Medieval Welsh literature, but it emerged after his death that he had forged several manuscripts, notably some of the Third Series of Welsh Triads. Even so, he had a lasting impact on Welsh culture, notably in founding the secret society known as the Gorsedd, through which Iolo Morganwg successfully co-opted the 18th-century Eisteddfod revival. The philosophy he spread in his forgeries has had an enormous impact upon neo-Druidism. His bardic name is Welsh for "Iolo of Glamorgan".
Rhun ap Maelgwn Gwynedd, also known as Rhun Hir ap Maelgwn Gwynedd, sometimes spelt as 'Rhûn', was King of Gwynedd. He came to the throne on the death of his father, King Maelgwn Gwynedd. There are no historical records of his reign in this early age. A story preserved in both the Venedotian Code and an elegy by Taliesin says that he waged a war against Rhydderch Hael of Alt Clut and the kings of Gododdin or Manaw Gododdin. The small scattered settlement of Caerhun in the Conwy valley is said to be named for him, though without strong authority. Rhun also appears in several medieval literary stories, as well as in the Welsh Triads. His wife was Perwyr ferch Rhûn "Ryfeddfawr" and their son was Beli ap Rhun "Hîr".
Lludd Llaw Ereint, "Lludd of the Silver Hand", son of Beli Mawr, is a legendary hero from Welsh mythology. As Nudd Llaw Ereint he is the father of Gwyn ap Nudd. He is probably the source of king Lud from Geoffrey of Monmouth's History of the Kings of Britain.
The Coraniaid are a race of beings from Welsh mythology. They appear in the Middle Welsh prose tale Lludd and Llefelys, which survives in the Mabinogion and inserted into several texts of the Brut y Brenhinedd, a Welsh adaptation of Geoffrey of Monmouth's Historia Regum Britanniae. The Coraniaid figure in the tale as one of three plagues that affect Britain during the reign of King Lludd. They are characterized by a sense of hearing so acute that they can hear any word the wind touches, making action against them impossible.
Erwan Berthou was a French and Breton language poet, writer and neo-Druidic bard. His name is also spelled Erwan Bertou and Yves Berthou.
Brut y Brenhinedd is a collection of variant Middle Welsh versions of Geoffrey of Monmouth's Latin Historia Regum Britanniae. About 60 versions survive, with the earliest dating to the mid-13th century. Adaptations of Geoffrey's Historia were extremely popular throughout Western Europe during the Middle Ages, but the Brut proved especially influential in medieval Wales, where it was largely regarded as an accurate account of the early history of the Celtic Britons.
Lludd and Llefelys is a Middle Welsh prose tale written down in the 12th or 13th century; it was included in the Mabinogion by Lady Charlotte Guest in the 19th century. It tells of the Welsh hero Lludd Llaw Eraint, best known as King Lud son of Heli in Geoffrey of Monmouth's Historia Regum Britanniae, and his brother Llefelys.
Jean Le Fustec was a Breton bard, and the first Archdruid of the Goursez Vreizh. He is also known by his Breton language name Yann ab Gwilherm and his Druidic name Lemenik.
Morvarc'h is the name of a fabulous horse of Breton legend found in two folktales reworked in the 19th and 20th centuries. Though its name appears in older sources, it was invented or reinterpreted by Charles Guyot, who named it Morvark in his version of the legend of the city of Ys in 1926. It belongs to the "Queen of the North" Malgven, who gives it to her husband King Gradlon. Endowed with the ability to gallop on the waves, Morvarc'h is described as having a black coat and as breathing flames through its nostrils. It also appears in a Breton folktale about King Marc'h of Cornouaille. In the course of a deer hunt it is killed by its own rider's arrow, which has been turned around by the spell of Dahud, the daughter of Malgven. She then puts the ears of the horse Morvarc'h on the head of King Marc'h, who seeks in vain to hide them.
Abbot Placide Guillermic, nicknamed Tadig Kozh,, was a Catholic priest and canon mythologized by Breton beliefs. Little biographical information is known about him, but eyewitness accounts mention the exorcisms this rector of Bégard performed at Méné-Bré in the Saint-Hervé chapel. Anatole Le Braz recounts that Tadig Kozh possessed knowledge of life and death, as well as supernatural powers, enabling him to reincarnate indefinitely, and to command demons and the wind. According to Claude Sterckx, Tadig Kozh is one of the few characters from Breton folklore who can be directly linked to themes from Celtic mythology, in particular Merlin.
