During the Middle Ages and early modern times tables were a most successful and economical way to present mathematical procedures and astronomical models and to facilitate computations. Before the sixteenth century astronomical models introduced by Ptolemy in Antiquity were rarely challenged, and innovation consisted in elaborating new methods for calculating planetary positions and other celestial phenomena. Essays on Medieval Computational Astronomy includes twelve articles that focus on astronomical tables, offering many examples where the meaning and purpose of such tables has been determined by careful analysis. In evaluating the work of medieval scholars we are mindful of the importance of applying criteria consistent with their own time, which may be different from those appropriate for other periods.

During the late Byzantine period (1261-1453), a significant number of texts were translated from Latin, but also from Arabic and other languages, into Greek. Most of them are still unedited or available in editions that do not meet the modern academic criteria. Nowadays, these translations are attracting scholarly attention, as it is widely recognized that, besides their philological importance per se, they can shed light on the cultural interactions between late Byzantines and their neighbours or predecessors. To address this desideratum, this volume focuses on the cultural context, the translators and the texts produced during the Palaeologan era, extending as well till the end of 15th c. in ex-Byzantine territories. By shedding light on the translation activity of late Byzantine scholars, this volume aims at revealing the cultural aspect of late Byzantine openness to its neighbours.

During the later Middle Ages (twelfth to fifteenth centuries), the study of chronology, astronomy, and scriptural exegesis among Christian scholars gave rise to Latin treatises that dealt specifically with the Jewish calendar and its adaptation to Christian purposes. In Medieval Latin Christian Texts on the Jewish Calendar C. Philipp E. Nothaft offers the first assessment of this phenomenon in the form of critical editions, English translations, and in-depth studies of five key texts, which together shed fascinating new light on the avenues of intellectual exchange between medieval Jews and Christians.

This groundbreaking volume provides an up-to-date, accessible guide to Sanskrit astronomical tables and their analysis. It begins with an overview of Indian mathematical astronomy and its literature, including table texts, in the context of history of pre-modern astronomy. It then discusses the primary mathematical astronomy content of table texts and the attempted taxonomy of this genre before diving into the broad outlines of their representation in the Sanskrit scientific manuscript corpus. Finally, the authors survey the major categories of individual tables compiled in these texts, complete with brief analyses of some of the methods for constructing and using them, and then chronicle the evolution of the table-text genre and the impacts of its changing role on the discipline of Sanskrit jyotiṣa. There are also three appendices: one inventories all the identified individual works in the genre currently known to the authors; one provides reference information about the details of all the notational, calendric, astronomical, and other classification systems invoked in the study; and one serves as a glossary of the relevant Sanskrit terms.

This innovative collection showcases the importance of the relationship between translation and experience in premodern science, bringing together an interdisciplinary group of scholars to offer a nuanced understanding of knowledge transfer across premodern time and space. The volume considers experience as a tool and object of science in the premodern world, using this idea as a jumping-off point from which to view translation as a process of interaction between diff erent epistemic domains. The book is structured around four dimensions of translation—between terms within and across languages; across sciences and scientific norms; between verbal and visual systems; and through the expertise of practitioners and translators—which raise key questions on what constituted experience of the natural world in the premodern area and the impact of translation processes and agents in shaping experience. Providing a wide-ranging global account of historical studies on the travel and translation of experience in the premodern world, this book will be of interest to scholars in history, the history of translation, and the history and philosophy of science.

Named a Best Book of 2020 by The Telegraph, The Times, and BBC History Magazine An illuminating guide to the scientific and technological achievements of the Middle Ages through the life of a crusading astronomer-monk. "Falk’s bubbling curiosity and strong sense of storytelling always swept me along. By the end, The Light Ages didn’t just broaden my conception of science; even as I scrolled away on my Kindle, it felt like I was sitting alongside Westwyk at St. Albans abbey, leafing through dusty manuscripts by candlelight." —Alex Orlando, Discover Soaring Gothic cathedrals, violent crusades, the Black Death: these are the dramatic forces that shaped the medieval era. But the so-called Dark Ages also gave us the first universities, eyeglasses, and mechanical clocks. As medieval thinkers sought to understand the world around them, from the passing of the seasons to the stars in the sky, they came to develop a vibrant scientific culture. In The Light Ages, Cambridge science historian Seb Falk takes us on a tour of medieval science through the eyes of one fourteenth-century monk, John of Westwyk. Born in a rural manor, educated in England’s grandest monastery, and then exiled to a clifftop priory, Westwyk was an intrepid crusader, inventor, and astrologer. From multiplying Roman numerals to navigating by the stars, curing disease, and telling time with an ancient astrolabe, we learn emerging science alongside Westwyk and travel with him through the length and breadth of England and beyond its shores. On our way, we encounter a remarkable cast of characters: the clock-building English abbot with leprosy, the French craftsman-turned-spy, and the Persian polymath who founded the world’s most advanced observatory. The Light Ages offers a gripping story of the struggles and successes of an ordinary man in a precarious world and conjures a vivid picture of medieval life as we have never seen it before. An enlightening history that argues that these times weren’t so dark after all, The Light Ages shows how medieval ideas continue to color how we see the world today.

The Gregorian calendar reform of 1582, which provided the basis for the civil and Western ecclesiastical calendars still in use today, has often been seen as a triumph of early modern scientific culture or an expression of papal ambition in the wake of the Counter-Reformation. Much less attention has been paid to reform's intellectual roots in the European Middle Ages, when the reckoning of time by means of calendrical cycles was a topic of central importance to learned culture, as impressively documented by the survival of relevant texts and tables in thousands of manuscripts copied before 1500. For centuries prior to the Gregorian reform, astronomers, mathematicians, theologians, and even Church councils had been debating the necessity of improving or emending the existing ecclesiastical calendar, which throughout the Middle Ages kept losing touch with the astronomical phenomena at an alarming pace. Scandalous Error is the first comprehensive study of the medieval literature devoted to the calendar problem and its cultural and scientific contexts. It examines how the importance of ordering liturgical time by means of a calendar that comprised both solar and lunar components posed a technical-astronomical problem to medieval society and details the often sophisticated ways in which computists and churchmen reacted to this challenge. By drawing attention to the numerous connecting paths that existed between calendars and mathematical astronomy between the Fall of Rome and the end of the fifteenth century, the volume offers substantial new insights on the place of exact science in medieval culture.

Two opposing views of the future in the Middle Ages dominate recent historical scholarship. According to one opinion, medieval societies were expecting the near end of the world and therefore had no concept of the future. According to the other opinion, the expectation of the near end created a drive to change the world for the better and thus for innovation. Close inspection of the history of prognostication reveals the continuous attempts and multifold methods to recognize and interpret God’s will, the prodigies of nature, and the patterns of time. That proves, on the one hand, the constant human uncertainty facing the contingencies of the future. On the other hand, it demonstrates the firm believe during the Middle Ages in a future which could be shaped and even manipulated. The handbook provides the first overview of current historical research on medieval prognostication. It considers the entangled influences and transmissions between Christian, Jewish, Islamic, and non-monotheistic societies during the period from a wide range of perspectives. An international team of 63 renowned authors from about a dozen different academic disciplines contributed to this comprehensive overview.
