Orderic Vitalis (; 16 February 1075 – ) 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. Modern historians view him as a reliable source.
Background
Orderic was born on 16 February 1075 in Atcham, Shropshire, England, the eldest son of a French priest, Odelerius of Orléans, who had entered the service of Roger de Montgomery, 1st Earl of Shrewsbury, and had received from his patron a chapel there. By the late 11th century, clerical marriage was still not uncommon in western Christendom. Orderic was one of the few monks who were of mixed parentage as his mother was of English heritage. When Orderic was five, his parents sent him to an English monk, Siward by name, who kept a school in the Abbey of SS Peter and Paul at Shrewsbury.
At the age of ten, Orderic was entrusted as an oblate to the Abbey of Saint-Evroul in the Duchy of Normandy, which Montgomery had formerly despoiled but, in his later years, was loading with gifts. The parents paid thirty marks for their son's admission; he expresses the conviction that they imposed this exile upon him from an earnest desire for his welfare. Odelerius's respect for the monastic life is attested to by his own entry, a few years later, into a monastery which the earl had founded at his persuasion. Orderic, on the other hand, felt for some time, as he asserts, like Joseph in a strange land. He did not know a word of French when he reached Normandy. His book, though written many years later, shows that he never lost his English cast of mind or his attachment to the country of his birth.
Monastic life
When Orderic reached the legal age for profession as a monk, his monastic superiors gave him the religious name of "Vitalis" (after a member of the legendary Theban Legion of Christian martyrs) because they found it difficult to pronounce his English baptismal name of Orderic, a name he says was the same as the priest who baptised him. In the title of his great chronicle, he prefixes the old to the new name and proudly adds the epithet Angligena ("English-born").
Orderic's cloistered life was uneventful. He became a deacon in 1093, and a priest in 1107. He left his cloister on several occasions, speaking of having visited Croyland, Worcester, Cambrai (1105) and Cluny Abbey (1132). He turned his attention at an early date to literature, and for many years appears to have spent his summers in the scriptorium.
Orderic's first literary efforts were a continuation and revision of William of Jumièges' Gesta normannorum ducum, a broad history of the Normans and their dukes from the founding of Normandy, which Orderic carried forward into the early twelfth century. He also added information about earlier periods from other sources, for example William of Poitiers' Gesta Guillelmi, and included information not found elsewhere. As Orderic used Norman sources but wrote from an English perspective, his account of the Norman Conquest is balanced, he is sympathetic to both sides. This attitude persists in his Historia Ecclesiastica.
