Anglo-Saxon theologian, historian, and chronologist, best known today for his Historia ecclesiastica gentis Anglorum (“Ecclesiastical History of the English People”), a source vital to the history of the conversion to Christianity of the Anglo-Saxon tribes. During his lifetime and throughout the Middle Ages Bede's reputation was based mainly on his scriptural commentaries, copies of which found their way to many of the monastic libraries of western Europe. His method of dating events from the time of the incarnation, or Christ's birth—i.e., AD—came into general use through the popularity of the Historia ecclesiastica and the two works on chronology. Bede's influence was perpetuated at home through the school founded at York by his pupil Archbishop Egbert of York and was transmitted to the Continent by Alcuin, who studied there before becoming master of Charlemagne's palace school at Aachen.

Nothing is known of Bede's parentage. At the age of seven he was taken to the Monastery of St. Peter, founded at Wearmouth (near Sunderland, Durham) by Abbot St. Benedict Biscop, to whose care he was entrusted. By 685 he was moved to Biscop's newer Monastery of St. Paul at Jarrow. Bede was ordained deacon when 19 years old and priest when 30. Apart from visits to Lindisfarne and York, he seems never to have left Wearmouth–Jarrow. Buried at Jarrow, his remains were removed to Durham and are now entombed in the Galilee Chapel of Durham Cathedral.

Bede's works fall into three groups: grammatical and “scientific,” scriptural commentary, and historical and biographical. His earliest works include treatises on spelling, hymns, figures of speech, verse, and epigrams. His first treatise on chronology, De temporibus (“On Times”), with a brief chronicle attached, was written in 703. In 725 he completed a greatly amplified version, De temporum ratione (“On the Reckoning of Time”), with a much longer chronicle. Both these books were mainly concerned with the reckoning of Easter. His earliest biblical commentary was probably that on the Revelation to John (703?–709); in this and many similar works, his aim was to transmit and explain relevant passages from the Fathers of the Church. Although his interpretations were mainly allegorical, treating much of the biblical text as symbolic of deeper meanings, he used some critical judgment and attempted to rationalize discrepancies. Among his most notable are his verse (705–716) and prose (before 721) lives of St. Cuthbert, bishop of Lindisfarne. These works are uncritical and abound with accounts of miracles; a more exclusively historical work is Historia abbatum (c. 725; “Lives of the Abbots”).

In 731/732 Bede completed his Historia ecclesiastica. Divided into five books, it recorded events in Britain from the raids by Julius Caesar (55–54 BC) to the arrival in Kent (AD 597) of St. Augustine. For his sources he claimed the authority of ancient letters, the “traditions of our forefathers,” and his own knowledge of contemporary events. Bede's Historia ecclesiastica leaves gaps tantalizing to secular historians. Although overloaded with the miraculous, it is the work of a scholar anxious to assess the accuracy of his sources and to record only what he regarded as trustworthy evidence. It remains an indispensable source for some of the facts and much of the feel of early Anglo-Saxon history.
