Byrhtferth’s Enchiridion (Early English Text Society Supplementary Series)

Byrthfert of Ramsey was one of the outstanding scholars produced by the late Anglo-Saxon church; in the year 1011 he completed his principle work, the Enchiridion, a handbook designed to explain the complexities of medieval date-reckoning–called computus. Never before adequately edited, this new edition illuminates our knowledge of scientific scholarship in the eleventh century. The text is accompanied by a full introduction, apparatus criticus, facing English translation, and detailed commentary. Also included is an appendix containing the Latin computus which the Enchiridion was designed to elucidate and glossaries of the Old English and difficult Latin words occurring in the Enchiridion itself.
