Ordericus Vitalis(ôrdĕr`ĭkəs vĭtăl`ĭs), 1075–c.1143, Norman monk and chronicler, b. England. He spent most of his life in Saint-Évroul in Normandy. His Ecclesiastical History (4 vol., tr. 1853–56; repr. 1968), a universal history to 1143, is valuable for a study of the Normans in England, France, and Italy and for the history of his own times.
