The conference was held as part of a project to compile a catalogue of Irish manuscripts containing scientific texts in Latin in AD 600-800. The 10 papers explore medieval efforts to compute the date of Easter, and the mathematics and astronomy that grew from the endeavor, with a special interest in the contribution that Irish and English monks made. Among the topics are the argumenta of Dionysius Exiguus and their early recensions, the recension of the two Sirmond texts Disputation Morini and De deuisionibus temporum, marital discord in Northumbria leading to his and her Lent and Easter, Bede's primary source for the Vulgate chronology in his chronicles in De temporibus and De temporum ratione, problems in the transmission of De temporibus, computus in Hiberno-Latin literature, and the continuity of the Irish computistical tradition. One of the papers is in France, and two in German. Distributed in North America by The David Brown Book Co. Annotation ©2010 Book News, Inc., Portland, OR (booknews.com)
