This chapter follows the story of calendar reform from the end of the twelfth to the end of the thirteenth century, showing how during this period the problem was popularized via two different categories of computus text: the pedagogically oriented ‘vulgar’ or ecclesiastical computus and the astronomically refined ‘philosophical’ computus. Authors whose contributions to the debate are looked at in greater detail include Alexander Neckam, John of Sacrobosco, Robert Grosseteste, Robert Holcot, Campanus of Novara, Giles of Lessines, and Roger Bacon, who is well known for having directed a reform appeal to Pope Clement IV (1265–8). Attention is also paid to an obscure group of Franciscan scholars active in the 1270s to 1290s, who are noteworthy for their knowledge of the Jewish calendar, and to an anonymous treatise of 1276, which contains the first fully developed proposal to restore the Roman calendar.Less

This chapter focuses on the first serious effort made within the medieval Latin Church to correct the calculation of Easter by legislative means. This effort took place at the court of Pope Clement VI in Avignon, who invited skilled astronomers such as Jean des Murs and Firmin de Beauval to assist him in a planned reform of the Golden Number. The chapter explores the background to this papal initiative and the contributions made by its various protagonists, focusing in particular on a recently discovered Expositio kalendarii novi written by the monk Johannes de Termis in 1345. It also takes a closer look at the parallel discussions that took place in the Byzantine East, where the prospect of a calendar reform was first raised by Nicephorus Gregoras in 1324.Less
