Theodore of Tarsus was Archbishop of Canterbury from 668 to 690. Theodore grew up in Tarsus, but fled to Constantinople after the Persian Empire conquered Tarsus and other cities. After studying there, he relocated to Rome and was later installed as the Archbishop of Canterbury on the orders of Pope Vitalian. Accounts of his life appear in two 8th-century texts. Theodore is best known for his reform of the English Church and establishment of a school in Canterbury.

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.
