The Book of Llandaff is one of the oldest manuscripts of Wales. While its core is a gospelbook containing a copy of St Matthew’s Gospel, it is best known for its many substantial additions in the form of the Lives of St Elgar and St Samson, and various documents (such as charters) relating to the see of Llandaff and to bishops Dyfrig, Teilo and Euddogwy.

Southumbrian, probably Mercian liturgical manuscript of the early 9th century containing extracts from the four Gospels, a collection of hymns and prayers, and an abbreviated Psalter. It is introduced by an Old English exhortation to prayer and concludes with a dramatic piece about the Harrowing of Hell. Signs of Irish influence in the style and contents of the manuscript have led scholars to regard the Book of Cerne as a witness to a shared Hiberno-Saxon monastic culture, although some of the details are disputed.
