Bede wrote many scientific, historical and theological works in his time. Many were copied and used by other monasteries in England and Western Europe. He had one work in particular that he is famous for. One of the most valuable and important sources on Anglo-Saxon history is Bede's "Ecclesiastical History of the English Nation". Bede spent most of his life at Jarrow and this is where he wrote his history. The History is made up of five books and about 400 pages written in Latin. It contains 800 years of the history of England from the time of Caesar to the date of its completion (731). The last chapter is about Bede himself.
