Fifth of 6 volumes.. The project to edit the Hyde Breviary was a considerable one that was to occupy the HBS for a decade. Hyde Abbey hadbeen founded alongside New Minster, Winchester un 965 by St Ethelwold [c. 908-984], Bishop if Winchester, and a former Abbot of Abingdon, with Abingdon Monks. In 1110 the community moved from its cramped premises to Hyde Meadow, just outside the city walls. The breviary MSS edited were most probably written during thre abbacy of Symon de Kanings [1292-1304]. The Hyde Breviary is one of a small number of surviving MS witneses to the form of the English Benedictine breviary, supplemented by what Tolhurst thought was a single surviving volume of a 1528 printed breviary or portiforium of Abingdon. The Hyde relics were here cosen as the most typical and informative. The Rawlinson and Gough MSS were written by different scribes but on virtuallly indistinguishable vellum and with illuminations from the same hand. Here they are collated with survivg witnesses to the English Benedictine breviary of the period. The final volume of the set is ‘Introduction to the English Monastic Breviaries’, volume 80 in the series.
