Orderic Vitalis was a Benedictine monk and historian born around 1075 in England. He is best known for his work, the "Ecclesiastical History," which chronicles the history of England and Normandy from the time of William the Conqueror to his own era. His writings provide valuable insights into the social, political, and religious life of the 11th and 12th centuries. Vitalis was of mixed heritage, with a father from Normandy and a mother from England. His unique background allowed him to offer a perspective that bridged both cultures. His detailed accounts are considered essential for understanding medieval history, particularly the Norman Conquest and its aftermath.
