C. Philipp E. Nothaft studied modern and ancient history and philosophy at the University of Munich, where he obtained a PhD in history in 2011. He has since held positions at the Hebrew University of Jerusalem (Martin Buber Society of Fellows in the Humanities), University College London (research associate at the Department of Hebrew and Jewish Studies), and the Warburg Institute (Frances A. Yates Long-term Fellow). In 2015, he became a Post-Doctoral Research Fellow at All Souls College, Oxford. His principal research topic are the intertwined histories of mathematical astronomy, chronology, and time-reckoning in medieval and early modern Europe. A major component of his work in these fields consists in the analysis and critical editing of unpublished sources in medieval Latin manuscripts.

Transformations of Medieval Astronomy, 1000–1250

The project aims at a thorough re-evaluation of the development of medieval Latin astronomy in the watershed period from 1000 to 1250, which is characterized by the assimilation of new knowledge from Islamic sources. Based on the analysis of unstudied or neglected source texts, the project seeks to provide fresh insights concerning two closely interlocking themes: (a) the role of observation and empirical modes of thinking in the mathematical astronomy practiced in this period and (b) the ways in which Latin astronomers assimilated new forms of knowledge from Islamic sources and their motivations for doing so. Many of the sources relevant to addressing these issues remain unknown and unedited, which is why an integral part of the project will be devoted to the examination of neglected manuscripts from European libraries and to the production of critical editions of sources of major significance. These editions will ultimately support a synthetic book-length study of the history of astronomy in Latin Europe in the early and high Middle Ages.
