The Vita Sancti Wilfrithi or Life of St Wilfrid is an early 8th-century hagiographic text recounting the life of the Northumbrian bishop, Wilfrid. Although a hagiography, it has few miracles, while its main concerns are with the politics of the Northumbrian church and the history of the monasteries of Ripon and Hexham. It is one of a collection of historical sources from the late 7th- and early 8th-centuries, along with the anonymous Vita Sancti Cuthberti, the works of Bede and Adomnán's Vita Sancti Columbae, that detail the Christianisation of Great Britain and make the period the best documented period in English history before the age of Alfred the Great.

Frithegod, was a poet and clergyman in the mid 10th-century who served Oda of Canterbury, an Archbishop of Canterbury. As a non-native of England, he came to Canterbury and entered Oda's service as a teacher and scholar. After Oda's death he likely returned to the continent. His most influential writing was a poem on the life of Wilfrid, an 8th-century bishop and saint, named Breviloquium Vitae Wilfridi. Several manuscripts of this poem survive, as well as a few other of Frithegod's poems. He was also known for the complexity of his writings, with one historian even calling them "damnably difficult".
