The Durham Rite is a historical fusion of the Roman Rite and the Gallican Rite in the English bishopric of Durham.
The earliest document giving an account of liturgical services in the Diocese of Durham is the so-called "Rituale ecclesiæ Dunelmensis", also known as the "Ritual of King Aldfrith" [the King of Northumbria, who succeeded his brother Ecgfrith in 685, and who was a vir in scripturis doctissimus 'man most learned in the scriptures' (Bede, Historia ecclesiastica gentis Anglorum, IV, xxvi)]. The Manuscript (in the library of Durham cathedral, A, IV, 19) of the early ninth century contains capitula, chants and especially collects, from the Epiphany to Easter, then a proprium sanctorum, a commune sanctorum and many forms for blessings. The greater part has an interlinear Anglo-Saxon translation.
At the end various scribes have used up the blank pages to write out a miscellaneous collection of hymns and exorcisms and a list of contractions used in books of canon law. Its connexion with Durham and Northumberland is shown by various allusions, such as that to St. Cuthbert in a collect (intercedente beato Cudbertho Sacerdote; p. 185 of the Surtees Soc. edition). This fragment represents the fusion of the Roman and Gallican uses that had taken place all over North-Western Europe since the first Frankish Emperor Charlemagne (768-814) or even earlier (Duchesne, Origines du culte chrétien, 2nd ed., 89-99). Many parts of it exactly correspond to the Gregorian Sacramentary sent by Pope Adrian I to the emperor (between 784 and 791; Duchesne, op. cit., 114-119).
