Compotus, Correction and Regulation

Fresh from the recent conference at Georgetown University, on the dynamic coupling of aspectus and affectus, the next Ordered Universe colloquium takes another theme close to Grosseteste’s heart: calendrical reform and its related subjects, time, astronomy, medicine, as well as the dating of Easter. The colloquium takes place next week on the 19th and 20th April, at All Souls College, University of Oxford. We will be taking a longer view of compotus in England, and the background to Grosseteste’s own characteristic contribution to the area, the Compotus correctorius. Principally the scholars gathering in Oxford will examine Durham Cathedral Manuscript Hunter 100, a computistical album from the early twelfth century. Investigating the antecedents, and the details of the compendium, allows different light to be shed onto the culture of medieval scientific investigation. Exploring both the texts and images, as well as the communities in and for which the manuscript was produced, the colloquium will provide an in-depth analysis. Other papers will broaden the scope, thinking about the implications of compotus texts from theological and societal perspectives, before ending with a full treatment and discussion of Grosseteste’s place in compotus studies, and the importance of the Compotus correctorius in his scientific canon. With experts including Faith Wallis, Eric Ramírez Weaver, Alfed Lohr and Philipp Nothaft, as well as Ordered Universe regulars, the programme looks exciting!

We are extremely grateful to All Souls College, and especially to Dr Philipp Nothaft for supporting the colloquium, financially and organisationally as to Durham University and Dr Rosalind Green in the same capacity.

Heaven’s Above! An Interactive Exhibition

Well, it has been about three weeks since the Being Human, National Festival of Humanities activities took place in Durham. Philipp Nothaft’s magnificent lecture on the dating of Easter (just before Advent, appropriately) on the 18th November, which attracted an audience of over 80 and is available in video form, began events. The lecture took place Continue reading
