From the patristic age until the Gregorian calendar reform of 1582, computus -- the science of time reckoning and art of calendar construction -- was a matter of intense concern. Bede's The Reckoning of Time (De temporum ratione) was the first comprehensive treatise on this subject and the model and reference for all subsequent teaching discussion and criticism of the Christian calendar. It is a systematic exposition of the Julian solar calendar and the Paschal table of Dionysius Exiguus, with their related formulae for calculating dates. But it is more than a technical handbook. Bede sets calendar lore within a broad scientific framework and a coherent Christian concept of time, and incorporates themes as diverse as the theory of tides and the doctrine of the millennium. This translation of the full text of The Reckoning of Time includes an extensive historical introduction and a chapter-by-chapter commentary. It will interest historians of medieval science, theology, and education, Bede scholars and Anglo-Saxonists, liturgists, and Church historians. It will also serve as an accessible introduction to computus itself. Generations of medieval computists nourished their expertise in Bede's orderly presentation; modern scholars in quest of safe passage through this complex terrain can hope for no better guide.

Works prior to this book focused on Bede as not only a European, but also as an English scholar, historian, scientist, or a biographer of saints, and have used a traditional approach towards his explanation of the Bible. Bede's interpretation of his work, its continuous progress, and the reasons behind his hurried appointment to an authority almost as high as the Church Fathers are all topics examined within the text. Essays are by Roger Ray, Faith Wallis, Calvin B. Kendall, George Hardin Brown, Scott DeGregorio, Arthur G. Holder, Lawrence T. Martin, Walter Goffart, and Joyce Hill.

In one series, the original writings of the universally acknowledged teachers of the Catholic, Protestant, Eastern Orthodox, Jewish, and Islamic traditions have been critically selected, translated, and introduced by internationally recognized scholars and spiritual leaders. Book jacket.
