The Life of St AEthelwold is one of the most important and interesting sources for the history of Anglo-Saxon England and for the religious movements of western Europe in the tenth century. It was written around the year 1000 by Wulfstan of Winchester, who had been a student of AEthelwold; the Life, therefore, provides a firsthand account of the activities of the man who was the central force in the Benedictine reform movement of the later tenth century. It also reveals the nature of AEthelwold's education and contacts with continental monasticism, and shows why Winchester became a focal point of late Anglo-Saxon culture. The present book, by two well-known authorities in the field of Anglo-Latin literature, provides the first critical edition of Wulfstan's Life. It is accompanied by a translation, extensive historical notes, and a substantial introduction which treats both Wulfstan and Aethelwold in the light of recent scholarly research. Appendices provide editions of other texts relevant to the study of AEthelwold, including a Latin Life by his pupil AElfric, some verses by a twelfth-century Ely poet, and a previously unprinted Middle English poem on the saint. This is a valuable edition of a major source, which will be welcomed by all students of Anglo-Saxon England.
