De rebus incertis: Stephen of Liège and the Divine Office

ABSTRACT Most standard musicological references attribute to Bishop Stephen of Liège (†920) the composition of three Offices: for the Holy Trinity, the feast of Saint Lambert (bishop of Liège in the early eighth century to whom the city's cathedral is dedicated) and the Invention of Saint Stephen the protomartyr. From statements by Richarius, Stephen's successor at Liège, and Folcuin of Lobbes (both from the tenth century), and the eleventh-century account of Anselm of Liège, along with the evidence in Brussels, Bibliothèque royale, MS 14650-59 (a tenth-century manuscript produced at Liège during Stephen's episcopate), I conclude that Stephen of Liège did have a hand in the Offices for Saint Lambert and the Holy Trinity. Although he may have composed chants for Saint Lambert, he more likely revised existing ones for the Trinity. No tenth- or eleventh-century testimony attests the attribution of the Office for the Invention of Saint Stephen to Bishop Stephen.
