The earliest surviving example of a primitive breviary
The second volume includes the private prayers (some of which are in Old English), and contains a brief introduction and full indices. It concludes with a separate work issued by the Plainsong and Mediaeval Music Society: Pre-Conquest Antiphons from the Portiforium of Saint Wulfstan, Edited by Dom Anselm Hughes, Nashdom Abbey, Plainsong and Mediaeval Music Society, [London], 1958. This small work gives the music of 22 antiphons whose words are found in Corpus Christi manuscript 391, drawing upon pre-Conquest sources. Combined with material available in existing published editions this permits an almost complete reconstruction of the music of the Portiforium of St Wulfstan.
