the Abbey between 1010 until his death in 1025. Adémar learned calligraphy, to read, to compose and to notate liturgical chant, to compile and to revise liturgical books, and to compose and to write liturgical poetry, homilies, chronicles and hagiography. His life was mainly spent in writing and transcribing chant books and chronicles, and his principal work is a history entitled Chronicon Aquitanicum et Francicum or Historia Francorum. This is in three books and deals with Frankish history from the reign of Pharamond, king of the Franks, to 1028. The first two books are scarcely more than a copy of earlier histories of Frankish kings, such as the Liber Historiae Francorum, the Continuation of Fredegar and the Annales regni Francorum. The third book, which deals with the period from 814 to 1028, is of considerable historical importance. It relies partly on the Chronicon Aquitanicum, to which Adémar himself added a final notice for the year 1028. Forgery He embraced the developing tale that Saint Martial, the third century bishop who Christianized the Limoges district, had actually lived centuries earlier, and was in fact one of the original apostles. And he supplemented the less than scanty documentation for the alleged 'apostolicity' of Martial, first with a forged Life of Martial, as if composed by Martial's successor, Bishop Aurelian. To effect this claim, he composed an "Apostolic Mass" that still exists in Adémar's own hand. The local bishop and abbot seem to have cooperated in the project and the mass was first sung on Sunday, 3 August 1029. Unfortunately for Adémar, the liturgy was disrupted by a travelling monk, Benedict of Chiusa, who denounced the improved Vita of Martial as a provincial forgery and the new liturgy as offensive to God. The word spread, and the promising young monk was disgraced. Adémar's reaction was to build forgery upon forgery, inventing a Council of 1031 that confirmed the 'apostolic' status of Martial, even a forged papal letter. The reality of this pathological tissue of forgeries was only unravelled in the 1920s, by a historian, Louis Saltet. Mainstream Catholic historians ignored Saltet's revelations until the 1990s. In the long run, Adémar was successful. By the late 11th century, Martial was indeed venerated in Aquitaine as an apostle, though his legend was doubted elsewhere. In a very direct way, Adémar's Mass shows the power of liturgy to effect worship. Legacy According to James Grier, Professor
