This book provides a study and critical edition of the corpus of hymns sung by monks and canons in their services in England before the Norman Conquest. An eleventh-century Latin manuscript known as the Durham Hymnal, with its accompanying Old English interlinear gloss, makes up the core of the edition. An introduction and commentary include descriptions of relevant extant manuscripts and discussions of sources, liturgical use and music, as well as the phonology and vocabulary of the Old English gloss. A translation of the Latin text is provided.
