Geoffrey of Monmouth was a Catholic cleric from Monmouth, Wales, and one of the major figures in the development of British historiography and the popularity of tales of King Arthur. He is best known for his chronicle The History of the Kings of Britain which was widely popular in its day, being translated into other languages from its original Latin. It was given historical credence well into the 16th century, but is now considered historically unreliable.
In the Matter of Britain, Igraine is the mother of King Arthur. Igraine is also known in Latin as Igerna, in Welsh as Eigr, in French as Ygraine, in Le Morte d'Arthur as Ygrayne—often modernised as Igraine or Igreine—and in Parzival as Arnive. She becomes the wife of Uther Pendragon, after the death of her first husband, Gorlois.
Brutus, also called Brute of Troy, is a legendary descendant of the Trojan hero Aeneas, known in medieval British legend as the eponymous founder and first king of Britain. This legend first appears in the Historia Brittonum, an anonymous 9th-century historical compilation to which commentary was added by Nennius, but is best known from the account given by the 12th-century chronicler Geoffrey of Monmouth in his Historia Regum Britanniae.
Coel, also called Coel Hen and King Cole, is a figure prominent in Welsh literature and legend since the Middle Ages. Early Welsh tradition knew of a Coel Hen, a c. 4th-century leader in Roman or Sub-Roman Britain and the progenitor of several kingly lines in Yr Hen Ogledd, a region of the Brittonic-speaking area of what is now northern England and southern Scotland.
Rud Hud Hudibras was a legendary king of the Britons as recounted by Geoffrey of Monmouth. He was the son of King Leil and ruled during a civil war.
Leir was a legendary king of the Britons whose story was recounted by Geoffrey of Monmouth in his pseudohistorical 12th-century History of the Kings of Britain. According to Geoffrey's genealogy of the British dynasty, Leir's reign would have occurred around the 8th century BC, around the time of the founding of Rome. The story was modified and retold by William Shakespeare in his Jacobean tragedy King Lear.
Cunedagius was a legendary king of the Britons, as recounted by Geoffrey of Monmouth. He was the son of Henwinus, Duke of Cornwall, and Regan, the daughter of King Leir.
Historia regum Britanniae, originally called De gestis Britonum, is a pseudohistorical account of British history, written around 1136 by Geoffrey of Monmouth. It chronicles the lives of the kings of the Britons over the course of two thousand years, beginning with the Trojans founding the British nation and continuing until the Anglo-Saxons assumed control of much of Britain around the 7th century. It is one of the central pieces of the Matter of Britain.
Aurelius Conanus or Aurelius Caninus was a Brittonic king in 6th-century sub-Roman Britain. The only certain historical record of him is in the writings of his contemporary Gildas, who excoriates him as a tyrant. However, he may be identified with one of the several similarly named figures active in Britain during this period. In the 12th century Geoffrey of Monmouth adapted Gildas' account for his chronicle Historia Regum Britanniae, and thereafter Aurelius Conanus was remembered as a legendary King of Britain.
Cador is a legendary Duke of Cornwall, known chiefly through Geoffrey of Monmouth's pseudohistorical Historia Regum Britanniae and previous manuscript sources such as the Life of Carantoc. In Welsh genealogical records, he appears as Cado (Cadwr), the son of Cornish king Geraint. Early sources present him as a relative of King Arthur, though the details of their kinship are usually left unspecified.
The Brut or Roman de Brut by the poet Wace is a loose and expanded translation in almost 15,000 lines of Norman-French verse of Geoffrey of Monmouth's Latin History of the Kings of Britain. It was formerly known as the Brut d'Engleterre or Roman des Rois d'Angleterre, though Wace's own name for it was the Geste des Bretons, or Deeds of the Britons. Its genre is equivocal, being more than a chronicle but not quite a fully-fledged romance. It narrates a largely fictional version of Britain's story from its settlement by Brutus, a refugee from Troy, who gives the poem its name, through a thousand years of pseudohistory, including the story of king Leir, up to the Roman conquest, the introduction of Christianity, and the legends of sub-Roman Britain, ending with the reign of the 7th-century king Cadwallader. Especially prominent is its account of the life of King Arthur, the first in any vernacular language, which instigated and influenced a whole school of French Arthurian romances dealing with the Round Table – here making its first appearance in literature – and with the adventures of its various knights.
The Battle of Chester was a major victory for the Anglo-Saxons over the native Britons near the city of Chester, England in the early 7th century. Æthelfrith of Northumbria annihilated a combined force from the Welsh kingdoms of Powys and Rhôs, and possibly from Mercia as well. It resulted in the deaths of Welsh leaders Selyf Sarffgadau of Powys and Cadwal Crysban of Rhôs. Circumstantial evidence suggests that King Iago of Gwynedd may have also been killed. Other sources state the battle may have been in 613 or even as early as 607 or 605 AD.
Saint Tysilio was a Welsh bishop, prince and scholar, son of the reigning King of Powys, Brochwel Ysgithrog, maternal nephew of the great Abbot Dunod of Bangor Iscoed and an ecclesiastic who took a prominent part in the affairs of Wales during the distressful period at the opening of the 7th century.
Llefelys is a character in Welsh mythology appearing in the medieval Welsh tale Cyfranc Lludd a Llefelys. In the tale, Llefelys is king of Gaul while his brother Lludd is king of Britain. The tale appears in the Red Book of Hergest and the White Book of Rhydderch, the source texts for the Mabinogion, and embedded into various versions of the Brut y Brenhinedd, the Welsh adaptation of Geoffrey of Monmouth's Historia Regum Britanniae.
Pridwen was, according to the 12th-century writer Geoffrey of Monmouth, King Arthur's shield; it was adorned with an image of the Virgin Mary. Geoffrey's description of it draws on earlier Welsh traditions found in Preiddeu Annwfn, Culhwch and Olwen, and the Historia Brittonum. The shield is also named and described by Wace, Layamon, Roger of Wendover and Robert of Gloucester among other medieval writers, and it directly inspired the description of Sir Gawain's shield in Sir Gawain and the Green Knight.
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.
Walter of Oxford was a cleric and writer. He served as archdeacon of Oxford in the 12th century. Walter was a friend of Geoffrey of Monmouth, who claimed he got his chief source for the Historia Regum Britanniae from him.
A number of medieval chronicles of the history of Wales survive, notably the 9th century Historia Brittonum and the 10th century Annales Cambriae. These early chronicles are written in Latin, while from the 12th century, some are composed in Middle Welsh. The oldest surviving manuscripts of chronicles kept in the National Library of Wales, Aberystwyth date to the 13th century.
Goffar known as Goffar the Pict, was a pseudo-historical king of Aquitaine around the year 1000 BCE in Geoffrey of Monmouth's Historia Regum Britanniae. In the story, he was defeated by Brutus of Troy and Corineus on their way to Britain. Later histories of Britain and France included Goffar from Historia Regum Britanniae, and sometimes expanded the story with some additional details.
Gogmagog was a legendary giant in Welsh and later English mythology. According to Geoffrey of Monmouth's Historia Regum Britanniae, he was a giant inhabitant of Albion, thrown off a cliff during a wrestling match with Corineus. Gogmagog was the last of the Giants found by Brutus and his men inhabiting the land of Albion.
