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 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.

The Four Branches of the Mabinogi or Pedair Cainc Y Mabinogi are the earliest prose stories in the literature of Britain. Originally written in Wales in Middle Welsh, but widely available in translations, the Mabinogi is generally agreed to be a single work in four parts, or "branches." The interrelated tales can be read as mythology, political themes, romances, or magical fantasies. They appeal to a wide range of readers, from young children to the most sophisticated adult. The tales are popular today in book format, as storytelling or theatre performances; they appear in recordings and on film, and continue to inspire many reinterpretations in artwork and modern fiction.
Peredur son of Efrawg is one of the Three Welsh Romances associated with the Mabinogion.

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.
