Byrhtferth
English Christian monk
Byrhtferth (Old English: Byrhtferð; c. 970 – c. 1020) was a priest and monk who lived at Ramsey Abbey in Huntingdonshire (now part of Cambridgeshire) in England. He had a deep impact on the intellectual life of later Anglo-Saxon England and wrote many computistic, hagiographic, and historical works. He was a leading man of science and best known as the author of many different works (although he may not have written many of them). His Manual (Enchiridion), a scientific textbook, is Byrhtferth's best known work.
He studied with Abbo of Fleury, who was invited to Ramsey Abbey by Oswald of Worcester to help teach. Abbo was there during the period 985 to 987, and became a large influence on Byhrtferth who was interested in the same studies, such as history, logic, astronomy, and mathematics. We do not have contemporary biographies of Byrhtferth, and the only information we have is that given in his Manual and his Preface.
Works
Byrhtferth's signature appears on only two unpublished works, his Latin and Old English Manual, and Latin Preface. He also composed a Latin life of St. Egwin, compiled a chronicle of Northumbrian history in the 990s, wrote a Latin life of Oswald of Worcester (the Vita Oswaldi) about the year 1000, and it is suggested that he is responsible for the early sections of the Historia regum, or History of the Kings, attributed to Simeon of Durham.
