Beverley, Alfred of, chronicler, and sacrist of the collegiate church of St John the Evangelist and St John of Beverley wrote a history of Britain and England in nine chapters from its supposed foundation by the Trojan Brutus, down to the death of Henry I in 1135. Alfred's chief sources, in addition to Bede's Historia Ecclesiastica de Gentis Anglorum, are Geoffrey of Monmouth's Historia Regum Britanniae, Henry of Huntingdon's Historia Anglorum, The Chronicle of John of Worcester, and the Historia Regum, attributed to Symeon of Durham.e
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.
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.
The Trinovantēs or Trinobantes were one of the Celtic tribes of Pre-Roman Britain. Their territory was on the north side of the Thames estuary in current Essex, Hertfordshire and Suffolk, and included lands now located in Greater London. They were bordered to the north by the Iceni, and to the west by the Catuvellauni. Their name possibly derives from the Celtic intensive prefix "tri-" and a second element which was either "nowio" – new, so meaning "very new" in the sense of "newcomers", but possibly with an applied sense of vigor or liveliness ultimately meaning "the very vigorous people". Their capital was Camulodunum, one proposed site of the legendary Camelot.
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.
The Catuvellauni were a Celtic tribe or state of southeastern Britain before the Roman conquest, attested by inscriptions into the 4th century.
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.
Cunobeline was a king in pre-Roman Britain from about AD 9 until about AD 40. He is mentioned in passing by the classical historians Suetonius and Dio Cassius, and many coins bearing his inscription have been found. He controlled a substantial portion of south-eastern Britain, including the territories of the Catuvellauni and the Trinovantes, and is called "King of the Britons" by Suetonius. He appears to have been recognized by Roman emperor Augustus as a client king, as testified by the use of the Latin title Rex on his coins. Cunobeline appears in British legend as Cynfelyn (Welsh), Kymbelinus or Cymbeline, as in the play by William Shakespeare.
Tasciovanus was a historical king of the Catuvellauni tribe before the Roman conquest of Britain.
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.
Ingenius is a legendary king of the Britons as recounted by Geoffrey of Monmouth's pseudohistorical work Historia Regum Britanniae, written c. 1138 CE. Ingenius was the fourth son of King Morvidus and the brother of Gorbonianus, Archgallo, Elidurus, and Peredurus.
Nennius is a mythical prince of Britain at the time of Julius Caesar's invasions of Britain. His story appears in Geoffrey of Monmouth's History of the Kings of Britain (1136), a work whose contents are now considered largely fictional. In Middle Welsh versions of Geoffrey's Historia he was called Nynniaw.
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.
Julius Asclepiodotus was a Roman praetorian prefect who, according to the Historia Augusta, served under the emperors Aurelian, Probus and Diocletian, and was consul in 292. In 296, he assisted the western Caesar Constantius Chlorus in re-establishing Roman rule in Britain, following the illegal rules of Carausius and Allectus.
Peredur is the name of a number of men from the boundaries of history and legend in sub-Roman Britain. The Peredur who is most familiar to a modern audience is the character who made his entrance as a knight in the Arthurian world of Middle Welsh prose literature.
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.
Lucius Tiberius is a Western Roman procurator or emperor from Arthurian legend, who is killed in a war against King Arthur. First appearing in Geoffrey of Monmouth's Historia Regum Britanniae, Lucius also appears in later, particularly English literature such as the Alliterative Morte Arthure and Thomas Malory's Le Morte d'Arthur. The motif of a Roman Emperor defeated by Arthur appears in the Old French literature as well, notably in the Vulgate Cycle.
Mandubracius or Mandubratius was a king of the Trinovantes of south-eastern Britain in the 1st century BC.
Quintus Laberius Durus was a Roman military tribune who died during Julius Caesar's second expedition to Britain. Caesar describes how soon after landing in Kent, the Romans were attacked whilst building a camp by the native Britons. Before reinforcements could arrive, Laberius was killed. His burial site is traditionally the earthworks of Julliberrie's Grave near Chilham.
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.
