Robert of Torigni (also known as Roburtus de Monte) (c.1110–1186) was a Norman monk, prior, abbot and an important twelfth century chronicler.
He was born at Torigni-sur-Vire, Normandy c.1110 most probably to an aristocratic family but his family name was abandoned when he entered Bec Abbey in 1128 In 1149 Robert of Torigni became the prior of Bec replacing Roger de Bailleul who had by that time become abbot. In 1154 Robert became the abbot of Mont Saint-Michel in Normandy. In November 1158 Robert hosted kings Louis VII of France and Henry II of England at Mont Saint-Michel. Three years later Robert de Torigni, along with Achard of St. Victor, Bishop of Avranches, stood as sponsors (Godfathers) to Eleanor, born to Henry II of England and Queen Eleanor at Domfront in 1161. In 1163 he was in Rome. He was also known to have visited England representing Mont Saint-Michel. In June 1186 Robert died and was buried in the nave of the chapel at Mont Saint-Michel under a simple grave marker. In 1876 a lead disc was found in his coffin bearing his epitaph. The translation reads: Here lies Robert Torigni, abbot of this place, who ruled the monastery 32 years, and lived 80 years.
Robert developed a reputation as being a pious monk, an accomplished diplomat, a skilled organizer and a great lover and collector of books Under Robert de Torigni Mont Saint-Michel became a great center of learning with sixty monks producing copious manuscripts and a library collection so vast it was called the Cité des Livres (City of Books). Robert himself was called "The Great Librarian of the Mont". Robert's principal interest was not so much in man's path to salvation, or in the moral lessons of history; it was in what he called "chronography" (organizing historical events in chronological order). He made no attempts to interpret history but wrote plainly "without a trace of romance in his soul."
