Robert Grosseteste (1168/751253), Bishop of Lincoln from 12351253, is widely recognized as one of the key intellectual figures of medieval England and as a trailblazer in the history of scientific methodology. Few of his numerous philosophical and scientific writings circulated as widely as the Compotus, a treatise on time reckoning and calendrical astronomy apparently written during a period of study in Paris in the 1220s. Besides its strong and longlasting influence on later writers, Grosstestes Compotus is particularly noteworthy for its innovatory approach to the theory and practice of the ecclesiastical calendara subject of essential importance to the life of the Latin Church. Confronting traditional computistical doctrines with the lessons learned from GraecoArabic astronomy, Grosseteste offered his readers a critical and reformoriented take on the discipline, in which he proposed a specific version of the Islamic lunar as a substitute for the failing nineteenyear cycle the Church still employed to calculate the date of Easter. This new critical edition of Grossetestes Compotus contains the Latin text with an enface English translation. It is flanked by an extensive introduction and chapter commentary, which will provide valuable new insights into the texts purpose and disciplinary background, its date and biographical context, its sources, as well as its reception in later centuries.
