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
