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.
There are several compilations of Welsh manuscripts. The most important, from a Welsh-language literature standpoint, are:

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, 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.
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.
Lewys Glyn Cothi, also known as Llywelyn y Glyn, was a prominent 15th century Welsh poet who composed numerous poems in the Welsh language. He is one of the most important representatives of the Beirdd yr Uchelwyr or Cywyddwyr ("cywydd-men"), the itinerant professional poets of the period between the 1284 Statute of Rhuddlan and c. 1600.
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.
Brenhinoedd y Saeson is the medieval title of three Middle Welsh annalistic chronicles known from three 14th-century manuscripts recording events from 682 to the English conquest of Wales in 1282. The title Brenhinoedd y Saeson is found only in the rubric to the earlier of the two surviving manuscripts of version S: the other two texts are commonly known as Brut y Tywysogion, but this title is found only in manuscripts of the late 16th century and cannot be considered authentic.
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 Englynion y Beddau is a Middle Welsh verse catalogue listing the resting places (beddau) of legendary heroes. It consists of a series of englynion, or short stanzas in quantitative meter, and survives in a number of manuscripts. The collection is thought to be considerably older than its earliest manuscript, the 13th-century Black Book of Carmarthen, and provides an important early glimpse at medieval Welsh heroic tradition and topographical folklore.
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.
The Black Book of Chirk is a 13th-century Welsh-language manuscript, known also as the Chirk Codex. It is Peniarth 29 of the National Library of Wales, and deals with legal and historical matters. It contains also an elegy addressed at Llywelyn ap Iorwerth; king of Wales. This poem was probably written by his grandson Llywelyn ap Gruffudd who lived in the 13th century.
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.
Peniarth Manuscript 32 is a fifteenth-century volume of the laws of Hywel Dda that contains a brief chronicle from Gwrtheyrn Gwrtheneu to King John, Paul's Vision, the Tree of the Cross, Brutus Saxonum, and various englynion. It is beautifully written on vellum in the hand of the scribe responsible for the Mabinogion in the Red Book of Hergest, and is bound in white vellum.
Peniarth 20 is an early Welsh manuscript, written on parchment, that is part of the Peniarth collection in the National Library of Wales. It is also known as the Chronicle of the Princes because it contains an important version of the chronicle Brut y Tywysogion. Daniel Huws, the leading authority on Welsh manuscripts, has argued that the majority of Peniarth 20 dates from circa 1330. A date around the 15th century had previously been offered by J. Gwenogvryn Evans.
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.
Cyfoesi Myrddin a Gwenddydd ei Chwaer is an anonymous Middle Welsh poem of uncertain date consisting of 136 stanzas, mostly in englyn form. Myrddin, the legendary 6th-century North British bard and warrior, is depicted as being encouraged by his sister Gwenddydd to utter a series of prophecies detailing the future history of the kings of Gwynedd, leading up to an apocalyptic ending. The mood of the poem has been described as "one of despair and of loss of faith and trust in this world".
