C. Philipp E. Nothaft studied modern history, ancient history, and philosophy at the University of Munich, leaving with a PhD in modern history in 2011. He has since held positions at the Hebrew University, Jerusalem, at University College London, and at the Warburg Institute (University of London). He is currently a post-doctoral research fellow at All Souls College, Oxford. His past publications include three books and about forty articles, most of them revolving around the history of calendars, chronology, and astronomy in medieval and early modern Europe.
Nothaft's main achievement is to demonstrate the staggering variety of approaches and rich texture of medieval conversations around the technical problems of the calendar. The thirty black-and-white illustrations give the merest hint of the masses of unedited mathematical manuscripts through which the author has sifted. * Speculum * This essential volume reworks the well-established framework of medieval computus, providing a richer understanding of the place of the calendar in medieval astronomy. It belongs in every library that collects in medieval history or the history of science. * Stephen McCluskey, Journal of the History of Astronomy *
