Usuard

The Martyrology of Usuard is a work by Usuard, a monk of the Benedictine abbey of Saint-Germain-des-Prés. The prologue is dedicated to Charles the Bald indicating that it was undertaken at that monarch's instigation. It was apparently written shortly before the author's death in 875. The martyrology enjoyed consistent success throughout the Middle Ages, as evidenced by numerous surviving manuscripts. This martyrology synthesizes elements of the old Martyrologium Hieronymianum, the martyrology of Ado of Vienne, and an enhanced version of that of Bede, attributed to the archdeacon Florus of Lyon. It contains eleven hundred saints' lives. The martyrology is a compilation upon which the later Roman Martyrology depended closely until the twentieth century; it remained throughout the Middle Ages the most famous document of its kind. It is preserved to us in innumerable manuscripts, of which Henri Quentin gives a partial list.
