Toronto [et al.]: Centre for Medieval Studies, University of Toronto, 1979. 8vo, pp. xxvi, 100; fine copy in original orange cloth stamped in gilt and black. "At King Alfred's command, Bishop Waerferth of Worcester translated Gregory's Dialogues into English during the last quarter of the ninth century. About a century, or a century and a half later, between 950 and 1050, someone, probably again at Worcester, went through the translation with painstaking care, making thousands of changes in vocabulary and phrasing.
