Orderic Vitalis
Orderic Vitalis (Latin:Ordericus Vitalis; 1075 – c.1142) was an English chronicler and Benedictine monk who wrote one of the great contemporary chronicles of 11th- and 12th-century Normandy and Anglo-Norman England. The modern biographer of Henry I of England, C. Warren Hollister, called him "an honest and trustworthy guide to the history of his times".
