Reassigning an eleventh century monastic antiphoner: from Fosses to Glanfeuil (Paris, Bibliotheque nationale de France, MS lat. 12584)
This article argues that an eleventh or early twelfth century Benedictine antiphoner and graduale, Paris, Bibliotheque nationale de France, MS lat. 12584 thought to originate at the Parisian abbey of Fosses was actually produced at Glanfeuil, a small monastery in southern Anjou. It is important to establish the correct provenance of this manuscript, since it is widely used by scholars owing to its early date, completeness, and position as one of the six monastic offices used in Rene Jean Hesbert's Corpus antiphonalium officii. The comparison of several elements of the office of Paris lat. 12584 with identical elements from a genuine, contemporary antiphoner from Fosses, Paris, Bibliotheque nationale de France, MS lat. 12044 makes it clear that the former must come from Glanfeuil.
