The monk Rodulfus Glaber is best known for his Five Books of the Histories, a major source of information on events in the first half of the 11th century and the life and thought of an 11th-century monk. This edition, the first since 1866, presents the only critical text of the Histories along with a complete translation and full historical commentary. Including vivid accounts of the millennium, genuine and false relics, church building, and visions of saints and demons, this edition also includes Glaber's Life of his mentor, St. William of Dijon, the renowned monastic reformer.
