This 1996 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. It assembles textual evidence, some of it hitherto unpublished, based on all extant manuscripts. Of these, an eleventh-century Latin manuscript known as the 'Durham Hymnal', with its accompanying Old English interlinear gloss, provides the core of the edition and its base manuscript. An introduction and commentary include descriptions of the manuscripts concerned and discussions of the sources, liturgical use, and music of the hymns, as well as the phonology and vocabulary of the Old English gloss. The text of the hymns is accompanied by a translation of the Latin into modern English prose.
