In the early twenty-first century, we often ask whether there is life (intelligent or otherwise) in the cosmos, but almost never whether the heavens themselves are actually alive or animated, that is, infused somehow with a soul, the anima mundi, or some such entity. This was not the case in the Middle Ages, the Renaissance, or the early modern period. Although Aristotelians normally answered no to this question, Marsilio Ficino (1433–99) took a decidedly Platonic turn when he answered the question (...) positively, insistently, and consistently in a broad range of works over his entire philosophical career. By contrast, Giovanni Pico della Mirandola (1463–94), Ficino’s younger contemporary, began by embracing the new Platonic position but joined the Aristotelian fold in his later works. In this essay, I will briefly compare and contrast Ficino’s solid and consistent position with the changing trajectory of Pico’s views over the course of his short but intense career. This essay is an exploration of central themes and some preliminary reflections thereon. These essentially Platonic views of a living universe provide the conceptual and literary foundations for understanding this issue in the early modern period. (shrink)

While the link between navigation and astronomy is quite evident and its history has been extensively explored, the prognosticatory element included in astronomical knowledge has been almost completely left out. In the early modern world, the science of the stars also included prognostication known today as astrology. Together with astronomical learning, navigation also included astrology as a means to predict the success of a journey. This connection, however, has never been adequately researched. This paper makes the first broad study of (...) the tradition of astrology in navigation as well as its role in early modern globalization. It shows how astrological doctrine had its own tools for nautical prognostication. These could be used when dealing with the uncertainty of reaching the desired destination, to inquire about the condition of a loved one, or an important cargo. It was widely used, both in time and geographical context, by navigators and cosmographers for weather forecasting and elections for the start of a successful voyage. (shrink)

The doctrine of great conjunctions, first theorized by the Arab astrologer Albumasar in the De magnis coniunctionibus, is a form of general astrology characterized...

Johannes Müller von Königsberg (1436-1476), better known as Regiomontanus, is widely considered as the most influential astronomer and mathematician of 15th-century Europe. He was active as an astrologer and deemed astrology to be the queen of mathematical sciences. Despite this, Regiomontanus's astrological activity has yet to be fully explored. A brief examination of Regiomontanus's manuscripts shows that his astrological interests were accompanied by interests in the arts and in methods of prognostication. This article studies an unconventional astrological-chiromantical text, whose relevance (...) is threefold: a) it sheds new light on Regiomontanus's astrological interests; b) it enriches our knowledge of Regiomontanus's efforts to learn and understand Greek-Regiomontanus transcribed it into his own manuscript during his sojourn in Italy from 1460-1467; and c) it is the sole extant text in the Greek tradition that provides a system for prognostication from the study of a person's hand, the parts of which are considered as being under the domain of planets. The article provides an English translation of Regiomontanus's transcription, alongside a brief commentary, and studies the intellectual and historical context of that production through manuscript analysis.
