St. Bede the Venerable (born 672/673, traditionally Monkton in Jarrow, Northumbria [England]—died May 25, 735, Jarrow; canonized 1899; feast day May 25) was an Anglo-Saxon theologian, historian, and chronologist. St. Bede is best known 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. The method of dating events from the time of the incarnation, or Christ’s birth—i.e., AD (anno Domini, “in the year of our Lord”)—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 rest of Europe by Alcuin, who studied there before becoming master of Charlemagne’s palace school at Aachen.
