Divine grace
The diocese was also the birthplace of the theologian Nicolas de Clémenges (fourteenth or fifteenth century), who was canon and treasurer of the Church of Langres; of the Gallican canonist Edmond Richer (1560-1631); of the Jesuit Pierre Lemoine, author of an epic poem on St. Louis and of the work "La dévotion aisée" (1602–71); and of the philosopher Diderot (1713–84). The historian Raoul Glaber, monk of Cluny Abbey who died in 1050, was at the priory of St. Léger in this diocese when he was touched by Divine grace on the occasion of an apparition.
