Geoffrey of Monmouth in the context of Christian

The Matter of Britain (French: matière de Bretagne; Welsh: Mater Prydain; Cornish: Mater Brythain; Breton: Afer Breizh-Veur) is the body of medieval literature and legendary material associated with Great Britain and Brittany and the legendary kings and heroes associated with it, particularly King Arthur. The 12th-century writer Geoffrey of Monmouth's Historia Regum Britanniae (History of the Kings of Britain) is a central component of the Matter of Britain.

It was one of the three great Western story cycles recalled repeatedly in medieval literature, together with the Matter of France, which concerned the legends of Charlemagne and his companions, as well as the Matter of Rome, which included material derived from or inspired by classical mythology and classical history. Its pseudo-chronicle and chivalric romance works, written both in prose and verse, flourished from the 12th to the 16th century.

The following list of legendary kings of Britain (Welsh: brenin y Brythoniaid or brenin Prydain) derives predominantly from Geoffrey of Monmouth's circa 1136 work Historia Regum Britanniae ("the History of the Kings of Britain"). Geoffrey constructed a largely fictional history for the Britons (ancestors of the Welsh, the Cornish and the Bretons), partly based on the work of earlier medieval historians like Gildas, Nennius and Bede, partly from Welsh genealogies and saints' lives, partly from sources now lost and unidentifiable, and partly from his own imagination (see bibliography). Several of his kings are based on genuine historical figures, but appear in unhistorical narratives. A number of Middle Welsh versions of Geoffrey's Historia exist. All post-date Geoffrey's text, but may give us some insight into any native traditions Geoffrey may have drawn on.

Geoffrey's narrative begins with the exiled Trojan prince Brutus, after whom Britain is supposedly named, a tradition previously recorded in less elaborate form in the 9th century Historia Brittonum. Brutus is a descendant of Aeneas, the legendary Trojan ancestor of the founders of Rome, and his story is evidently related to Roman foundation legends.

Historia regum Britanniae (The History of the Kings of Britain), originally called De gestis Britonum (On the Deeds of the Britons), is a fictitious 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.

Although taken as historical truth until the 16th century, it is now considered to have no value as history. When events described, such as Julius Caesar's invasions of Britain, can be corroborated from contemporary histories, Geoffrey's account can be seen to be wildly inaccurate. It remains, however, a valuable piece of medieval literature, which contains the earliest known version of the story of King Lear and his three daughters, and helped popularise the legend of King Arthur.

Chivalry, or the chivalric language, is an informal and varying code of conduct that developed in Europe between 1170 and 1220. It is associated with the medieval Christian institution of knighthood, with knights being members of various chivalric orders, and with knights' and gentlemen's behaviours which were governed by chivalrous social codes. The ideals of chivalry were popularized in medieval literature, particularly the literary cycles known as the Matter of France, relating to the legendary companions of Charlemagne and his men-at-arms, the paladins, and the Matter of Britain, informed by Geoffrey of Monmouth's Historia Regum Britanniae, written in the 1130s, which popularized the legend of King Arthur and his knights of the Round Table.

The code of chivalry that developed in medieval Europe had its roots in earlier centuries. It arose in the Carolingian Empire from the idealisation of the cavalryman—involving military bravery, individual training, and service to others—especially in Francia, among horse soldiers in Charlemagne's cavalry. Over time, the meaning of chivalry in Europe has been refined to emphasize more general social and moral virtues. The code of chivalry, as it stood by the Late Middle Ages, was a moral system which combined a warrior ethos, knightly piety, and courtly manners, all combining to establish a notion of honour and nobility.

Layamon's Brut (c. 1190 – c. 1215), also known as The Chronicle of Britain, is a Middle English alliterative verse poem compiled and recast by the English priest Layamon. Layamon's Brut is 16,096 lines long and narrates a fictionalized version of the history of Britain up to the Early Middle Ages. It was the first work of history written in English since the Anglo-Saxon Chronicle. Named for Britain's mythical founder, Brutus of Troy, the poem is largely based on the Anglo-Norman French Roman de Brut by Wace, which is in turn a version of Geoffrey of Monmouth's Latin Historia Regum Britanniae. Layamon's poem, however, is longer than both and includes an enlarged section on the life and exploits of King Arthur. It is written in the alliterative verse style commonly used in Middle English poetry by rhyming chroniclers, the two halves of the alliterative lines being often linked by rhyme as well as by alliteration.

Like the earlier Latin works, it is now regarded as valueless as history. It gives the history of the Britons, largely ignoring the Anglo-Saxons. Its narrative ends with the Welsh king Cadwallon ap Cadfan, who died in 634.

The historicity of King Arthur has been debated both by academics and popular writers. While there have been many claims that King Arthur was a real historical person, the current consensus among specialists on the period holds him to be a mythological or folkloric figure.

The first definite mention of Arthur appears circa 828 in the Historia Brittonum, where he is presented as a military leader fighting against the invading Saxons in 5th- to 6th-century Sub-Roman Britain at the Battle of Badon, more than three centuries before the work was written. Arthur developed into a legendary figure in the Matter of Britain from the 12th century, following Geoffrey of Monmouth's influential but largely fictional Historia Regum Britanniae.

Welsh mythology, also known as Y Chwedlau (Welsh for 'the legends'), 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 (Welsh: derwyddon). 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 mediaeval 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 (History of the Britons) and Geoffrey of Monmouth's 12th-century Latin chronicle Historia Regum Britanniae (History of the Kings of Britain), as well as later Welsh folklore, such as the materials collected in The Welsh Fairy Book by William Jenkyn Thomas (1908).

Cadwaladr ap Cadwallon (also spelled Cadwalader or Cadwallader in English) was king of Gwynedd in Wales from around 655 to 664 or 682. He died in one of two devastating plagues that happened in 664 and in 682. Little else is known of his reign.

The red dragon (Welsh: y Ddraig Goch), long known as a Welsh symbol, appearing in the Mabinogion, the Historia Brittonum, and the stories of Geoffrey of Monmouth, has, since the accession of Henry VII to the English throne, often been referred to as "The Red Dragon of Cadwaladr". The association with Cadwaladr is a traditional one without any historical basis.

Brutus, also called Brute of Troy, is a mythical British king. He is described as a descendant of the Trojan hero Aeneas and 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.

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 reigned 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.

Merlin (Welsh: Myrddin, Cornish: Merdhyn, Breton: Merzhin) is a mythical figure prominently featured in the legend of King Arthur and best known as a magician, along with several other main roles. The familiar depiction of Merlin, based on an amalgamation of historical and legendary figures, was introduced by the 12th-century Catholic cleric Geoffrey of Monmouth and then built on by the French poet Robert de Boron and prose successors in the 13th century. Geoffrey’s account presented Merlin as both a prophet and royal advisor.

Geoffrey seems to have combined earlier Welsh tales of Myrddin and Ambrosius, two legendary Briton prophets with no connection to Arthur, to form the composite figure that he called Merlinus Ambrosius. His rendering of the character became immediately popular, especially in Wales. Later chronicle and romance writers in France and elsewhere expanded the account to produce a more full, multifaceted character, creating one of the most important figures in the imagination and literature of the Middle Ages.

Guinevere (/ˈɡwɪnəvɪər/ GWIN-ə-veer; Welsh: Gwenhwyfar pronunciation; Breton: Gwenivar, Cornish: Gwynnever), also often written in Modern English as Guenevere or Guenever, was, according to Arthurian legend, an early-medieval queen of Great Britain and the wife of King Arthur. First mentioned in literature in the early 12th century, nearly 700 years after the purported times of Arthur, Guinevere has since been portrayed as everything from a fatally flawed, villainous, and opportunistic traitor to a noble and virtuous lady. The variably told motif of abduction of Guinevere, or of her being rescued from some other peril, features recurrently and prominently in many versions of the legend.

The earliest datable appearance of Guinevere is in Geoffrey of Monmouth's pseudo-historical British chronicle Historia Regum Britanniae, in which she is seduced by Mordred during his ill-fated rebellion against Arthur. In a later medieval Arthurian romance tradition from France, a major story arc is the queen's tragic love affair with her husband's best knight and trusted friend, Lancelot, indirectly causing the death of Arthur and the downfall of the kingdom. This concept had originally appeared in nascent form in Chrétien de Troyes's poem Lancelot, the Knight of the Cart prior to its vast expansion in the prose cycle Lancelot-Grail, consequently forming much of the narrative core of Thomas Malory's seminal English compilation Le Morte d'Arthur. Other themes found in Malory and other texts include Guinevere's usual barrenness, the scheme of Guinevere's evil twin to replace her, and the particular hostility displayed towards Guinevere by her sister-in-law Morgan.

Perceforest or Le Roman de Perceforest is an anonymous prose chivalric romance, written in French probably around 1340 with lyrical interludes of poetry, that describes a fictional origin of Great Britain and provides an original genesis of the Arthurian world. The lengthy work in eight volumes (over one million words long) takes its inspiration from the works of Geoffrey of Monmouth, Wace, Orosius and Bede, the Lancelot-Grail cycle, the Alexander Romance genre, Roman historians, medieval travellers, and oral tradition. Perceforest forms a late addition to the collection of narratives with loose connections both to the Arthurian Romance and the feats of Alexander the Great.

The Brut or Roman de Brut (completed 1155) 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.

Russicada (present-day Skikda), was the Mediterranean port city serving Cirta, the capital of the Kingdom of Numidia in Ancient Algeria.

It overlooked the straits between Sicily (Europe) and Numidia (Africa), a place of significant relevance in geopolitical strategies at the time. Russicada was mentioned by the medieval chronicler Geoffrey of Monmouth in his pseudo-historical accounts of the mythical kings of Britain and their deeds as "Rusicada" — a Latin spelling easily confused with the moth genus Rusicada.
