The Ordinale and Customary of the Benedictine Nuns of Barking Abbey II : [University College, Oxford, Ms. 169]
The Ordinal and Customary of Barking Abbey was written on the instructions of Sibille Fenton, who was abbess from 1394 to 1419, and the manuscript was presented to the abbey in 1404. The liturgical usages regulated are almost entirely limited to the functioning of the choir. The text is one of a number of liturgical manuscripts which survive from Barking Abbey.
