Hildebert of Lavardin (c. 105518 December 1133) was a French ecclesiastic, hagiographer and theologian. From 1096–97 he was bishop of Le Mans, then from 1125 until his death archbishop of Tours.
Life
Hildebert was born of poor parents at Lavardin, near Vendôme, and was intended for the church. He was probably a pupil of Berengar of Tours, and became master (scholasticus) of the school at Le Mans; in 1091 he was made archdeacon and in 1096 or 1097 bishop of Le Mans. He had to face the hostility of a section of his clergy and also of the English king, William II, who captured Le Mans and carried the bishop with him to England for about a year.
Hildebert then (in 1100 or 1103) travelled to Rome and sought permission to resign his bishopric, which Pope Paschal II refused. In 1116 his diocese was thrown into great confusion owing to the preaching of Henry of Lausanne, who was denouncing the higher clergy, especially the bishop. Hildebert compelled him to leave the neighborhood of Le Mans, but the effects of his preaching remained.
Works
The extant writings of Hildebert consist of letters, poems, a few sermons, two lives and one or two treatises. An edition of his works prepared by the Maurist, Antoine Beaugendre, and entitled Venerabilis Hildeberti, prima Cenomanensis episcopi, deinde Turonensis archiepiscopi, opera tam edita quam inedita, was published in Paris in 1708 and was reprinted with additions by J-J Bourassé in 1854. These editions, however, are faulty. They credit Hildebert with numerous writings by others and omit some genuine writings. Revelation of this fact has affected Hildebert's position in the history of medieval thought. but whose attribution to Hildebert is very doubtful.
His poems on various subjects were also very popular. Hildebert attained celebrity also as a preacher both in French and Latin, but only a few of his genuine sermons exist, most of the 144 his editors attributed to him being the work of Peter Lombard and others.
