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.
The Red Book of Hergest, Oxford, Jesus College, MS 111, is a large vellum manuscript written shortly after 1382, which ranks as one of the most important medieval manuscripts written in the Welsh language. It preserves a collection of Welsh prose and poetry, notably the tales of the Mabinogion and Gogynfeirdd poetry. The manuscript derives its name from the colour of its leather binding and from its association with Hergest Court between the late 15th and early 17th century.
The National Library of Wales, in Aberystwyth, is the national legal deposit library of Wales and is one of the Welsh Government sponsored bodies. It is the biggest library in Wales, holding over 6.5 million books and periodicals, and the largest collections of archives, portraits, maps, and photographic images in Wales. The Library is also home to the national collection of Welsh manuscripts, the National Screen and Sound Archive of Wales, and the most comprehensive collection of paintings and topographical prints in Wales. As the primary research library and archive in Wales and one of the largest research libraries in the United Kingdom, the National Library is a member of Research Libraries UK (RLUK) and the Consortium of European Research Libraries (CERL).
The Welsh Triads are a group of related texts in medieval manuscripts which preserve fragments of Welsh folklore, mythology and traditional history in groups of three. The triad is a rhetorical form whereby objects are grouped together in threes, with a heading indicating the point of likeness; for example, "Three things not easily restrained, the flow of a torrent, the flight of an arrow, and the tongue of a fool."
The White Book of Rhydderch is one of the most notable and celebrated surviving manuscripts in Welsh. Mostly written in southwest Wales in the middle of the 14th century it is the earliest collection of Welsh prose texts, though it also contains some examples of early Welsh poetry. It is now part of the collection of the National Library of Wales, having been preserved in the library at Hengwrt, near Dolgellau, Gwynedd, of the 17th century antiquary Robert Vaughan, who inherited it from the calligrapher John Jones and passed it to his descendants. The collection later passed to the newly established National Library of Wales as the Peniarth or Hengwrt-Peniarth Manuscripts.
The Black Book of Carmarthen is thought to be the earliest surviving manuscript written solely in Welsh. The book dates from the mid-13th century; its name comes from its association with the Priory of St. John the Evangelist and Teulyddog at Carmarthen, and is referred to as black due to the colour of its binding. It is currently part of the collection of the National Library of Wales, where it is catalogued as NLW Peniarth MS 1.
Idwal Iwrch, or Idwal ap Cadwaladr, is a figure in the genealogies of the kings of Gwynedd. He was the son of King Cadwaladr ap Cadwallon and the father of King Rhodri Molwynog. William Wynne places Cynan Dindaethwy as his son, but other sources have Cynan as the son of Rhodri. The records of this era are scanty, and Idwal's name appears only in the pedigrees of later kings and in a prophecy found in two 14th-century Welsh manuscripts, which says that he will succeed his father Cadwaladr as king.
Brut y Tywysogion is one of the most important primary sources for Welsh history. It is an annalistic chronicle that serves as a continuation of Geoffrey of Monmouth’s Historia Regum Britanniae. Brut y Tywysogion has survived as several Welsh translations of an original Latin version, which has not itself survived. The most important versions are the one in Robert Vaughan's Peniarth MS. 20 and the slightly less complete one in the Red Book of Hergest. The version entitled Brenhinoedd y Saeson combines material from the Welsh annals with material from an English source.
The title King of the Britons was used to refer to a ruler, especially one who might be regarded as the most powerful, among the Celtic Britons, both before and after the period of Roman Britain up until the Norman invasion of Wales and the Norman conquest of England. Britons were the Brittonic-speaking peoples of what is now Wales, England and southern Scotland. The Britons contributed as ethnic ancestors of the native British population including the Welsh, Cornish, English and Scottish people but also of the Bretons.
Peredur son of Efrawg is one of the Three Welsh Romances associated with the Mabinogion. It tells a story roughly analogous to Chrétien de Troyes' unfinished romance Perceval, the Story of the Grail, but it contains many striking differences from that work, most notably the absence of the French poem's central object, the grail.
X/1106 C1, also known as the Great Comet of 1106, was a great comet that appeared on 2 February 1106, and was observed around the world from the beginning of February through to mid-March. It was recorded by astronomers in Wales, England, Japan, Korea, China, Continental Europe, and Egypt. It was observed to split into many pieces, forming the Great Comet of 1882 and Comet Ikeya–Seki as well as over 4000 small sungrazing comets observed by the SOHO space telescope. It is a member of the Kreutz Group, known as Subfragment I, a split from an earlier large (~150 km) comet that progressively fragmented under the influence of the Sun, possibly the Great Comet of 371 BC.
Brenhinoedd y Saeson is the medieval title of a Middle Welsh annalistic chronicle. The name means 'the kings of the English'.
Robert Powell Vaughan was an eminent Welsh antiquary and collector of manuscripts. His collection, later known as the Hengwrt–Peniarth Library from the houses in which it was successively preserved, formed the nucleus of the National Library of Wales, and is still in its care.
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.
The White Book of Hergest was an important Welsh manuscript compiled in c. 1450. It contained many Welsh poems and prose texts and was a significant source for several antiquaries of the 17th and 18th centuries, but disappeared in the early 19th century, probably being destroyed in a fire in a London bookbinder's shop in around 1810.
Brut y Saeson is a Welsh-language chronicle running from the death of Cadwaladr ap Cadwallon in 682 to the reign of Richard II (1377–99) of England. The name means the brut or chronicle of the English.
The Peniarth Manuscripts, also known as the Hengwrt–Peniarth Manuscripts, are a collection of medieval Welsh manuscripts now held by the National Library of Wales in Aberystwyth. The collection was originally assembled by Robert Vaughan of Hengwrt, Merionethshire. During the 19th century it was held in Peniarth Mansion, Llanegryn.
Wales has produced a number of manuscripts over the centuries. Although most were written in Middle Welsh or Old Welsh, some were also written in Latin. In some of the more recent manuscripts it is not uncommon to have texts in Welsh, Latin, French and English in the same volume. However, some of the most important medieval manuscripts were written in Latin only, e.g. the Cyfraith Hywel.
Hengwrt was a mansion near Dolgellau in Meirionnydd, Gwynedd. It lay in the parish of Llanelltyd near the confluence of the River Mawddach and River Wnion, near Cymer Abbey. With medieval origins, it was rebuilt or remodelled on several occasions before being demolished in 1962. It is remembered as the original home of the important collection of the Peniarth Manuscripts, now in the National Library of Wales.
