This volume offers a comprehensive examination of medieval conceptions of foreknowledge—understood both as divine prescience and as the human capacity to anticipate future events—across a range of intellectual traditions. It investigates key themes such as future contingents, prophetic discourse (both divinely inspired and natural), divinatory dreams, eschatology, scientific prognostication (in astrology and medicine), and conjectural disciplines such as geomancy, physiognomy, meteorology, and magic. Through historical reconstructions and doctrinal analyses, the contributions illuminate the theoretical frameworks and distinctive positions advanced by medieval authors within diverse cultural and scholarly contexts. Building on an extensive body of prior research, the volume documents the multiplicity of medieval strategies for engaging with the future, thereby challenging the historiographical assumption that the notion of an open and indeterminate future emerged only in the Modern period.

During the Middle Ages, physicians, philosophers, and theologians developed a complex and rich discourse on the concept of sickness. Illness (infirmitas) was perceived as the natural state of existential imperfection for homo viator, fallen due to sin and impaired in his bodily integrity. Leprosy, smallpox, plague and the other collective diseases that constantly plagued medieval societies prompted reflections on etiology and modes of transmission of epidemics. Building on Galenic teachings, medieval medicine – both Arabic and Latin – delved into the study of fevers. Key concepts in medical pathology, such as the humors, humidum radicale, and spiritus, were assimilated and reinterpreted within philosophical and theological frameworks. The ten contribution collected in this volume explore this rich array of concepts and themes by closely examining the theories and works of prominent and lesser-known figures in medicine, theology, and philosophy active across Latin Christendom, the Islamic context, and the Jewish world: from Augustine to ʿAlī ibn al-ʿAbbas al-Maǧūsī, from Avicenna to Constantine the African, from Maimonides to Albert the Great, from Arnau de Vilanova to Gentile da Foligno, from Henry of Herford to Michele Savonarola.

It has been argued that the thirteenth and fourteenth centuries were a crucial period in the medieval development of the idea of contagion. Theologians and physicians cooperated in devising a conceptual model based on medical literature (Hippocratico-Galenic and Avicennian) and formulated primarily to explain the origin, transmission, and development of contagious diseases, but that was flexible enough to be applied to a number of other different phenomena (the communication of sin and vices, love sickness, fascination, etc.). This article explores the ways in which Albert the Great contributed to the formation of this broad and highly articulated notion of contagion. First, he provided a systematic analysis of the mechanisms of pathogenesis and transmission of contagious diseases (in particular, pestilences and leprosy). Moreover, his interests encompassed several different forms of contagion, including the powers of stones (e.g., the attractive virtue of the magnet) and animals, the influences of the woman’s body and mind (mulier menstruata and vetula), fascination. Albert also provided different models for the explanation of the “contagious influence” (mechanical explanation based on physical contact, the Avicennian theory of psychosomatic transformations, the Avicennian doctrine of the power of the soul over external bodies, spiritual transmission of sins). As a result of his investigation into the mechanisms of disease transmission, air contamination, noxious influences, and fascination, Albert came to problematize the usual idea of natural causality based on the principle of contact between substances, and to test the potentials and limits of action at-a-distance. In particular, the present paper will examine Albert’s views on some of the phenomena explained through the concept of contagion: pestilences, leprosy, the basilisk, the menstruating woman, and fascination.

According to the doctrine of the Great Year, after a long period of time the same astral configurations reappear and the planets return to their original positions. The end of a world cycle is marked by a natural cataclysm, after which the world is restored to its original state and history repeats itself. This article deals with Albert the Great’s views on the Great Year, focussing on two of his early theological works (the De iv coaequaevis and the Sentences commentary). The evidence here provided offers a comprehensive overview of the variety of contexts and themes which Albert considers to be related to the Great Year. He is fully aware of the many doctrinal implications of the concept of the Great Year. His analysis is deeply embedded in the astronomical discussions on the phenomenon of the precession of the equinoxes. A predominantly scientific approach is evident in the care with which he distinguishes the different types of Great Year. The major contribution of these works to the debate lies in the analysis of the impact of the Great Year on Christian eschatology and, more generally, in the investigation of the relationship between astrology and physics, on the one hand, and eschatology, on the other.

The doctrine of great conjunctions, first theorized by the Arab astrologer Albumasar in the De magnis coniunctionibus (Book of Religions and Dynasties), is a form of general astrology characterized by the attempt to explain events affecting the Earth as a whole or in part (e.g. cataclysms – floods of water and fire, plagues, famine, etc. – the succession of civilizations, new empires, religions and prophets) as a consequence of the mean conjunctions of Saturn and Jupiter. The paper deals with Albert the Great’s remarkable contribution to the medieval debate on great conjunctions by focusing on a few passages from his De causis proprietatum elementorum and his Politica commentary (II 6 and V 9). The potential and risks posed by this all-embracing explanation of natural phenomena and the human domain did not escape Albert the Great. He grasped the subversive character of the universal determinism underlying the great conjunctions, as well as their scientific value. The first selection of his texts, mainly taken from the De causis proprietatum elementorum, establishes the scientific nature of conjunctionist theory. They elucidate its complex and sophisticated notions, describe the effects of planetary conjunctions on the sublunary world, and oppose this theory to pseudoscientific explanations of natural processes. Albert also discusses the epistemological status of conjunctionist theory, clarifying its relationship to other branches of astrology. By contrast, the texts from the Politica commentary relate the great conjunctions to human history and political processes, exploring the conflict between astral determinism and human responsibility.

Riassunto: La geomanzia, una disciplina divinatoria importata dal mondo arabo, prosperò nel medioevo latino. Di fronte a tale popolarità traduttori e autori di trattati geomantici, filosofi, teologi e letterati si interrogarono sulla sua validità, sulle sue implicazioni filosofiche e sulla visione del mondo che essa presupponeva. Il presente contributo esamina questo dibattito. In particolare, si ricostruisce lo statuto epistemologico della geomanzia nei suoi rapporti con l’astrologia. Il problema della scientificità della geomanzia viene discusso anche nel contesto dell’azione della causalità celeste sul mondo sublunare. Sono esaminati i ruoli del geomante e dell’interrogante ed è analizzato il concetto di intentio, che rimanda ad un’analisi psicologica peculiare della geomanzia. Caratterizza la geomanzia anche una dimensione rituale fatta di prescrizioni preliminari e di invocazioni da rivolgere alla divinità. Quanto detto impedisce di ridurre la geomanzia ad una semplice tecnica divinatoria; essa appare piuttosto una forma di sapienza rivelata solo al geomante esperto e moralmente degno, che attinge così la conoscenza di eventi futuri e cose nascoste. Da questa breve ricostruzione emerge l’articolata natura della geomanzia, contraddistinta, nella sua originaria versione araba, da una marcata impronta religiosa e da uno stretto, benché ambiguo, nesso con la profezia Islamica.: Geomancy, a divinatory discipline imported from the Arab world, flourished in the Latin Middle Ages. In the attempt to explain the popularity of geomancy, translators and authors of geomantic writings, philosophers, theologians, and other scholars addressed such issues as its validity, its philosophical implications, and the worldview it presupposed. This paper explores this debate, delineating the epistemological status of geomancy in relation to astrology. The problem of the scientificity of geomacy will be discussed with regard to the celestial influences on the sublunary world. In addition, the different roles played by both the geomancer and the consultant are examined. Attention will be paid to the concept of intentio, which implies a psychological analysis peculiar to geomancy. Geomancy is also characterized by ritual elements such as both preliminary prescriptions and invocations of God, meaning that it is not an ordinary divinatory technique, but a form of wisdom revealed only to experienced and upright geomancers, who can thus obtain knowledge of future events and hidden things. From this analysis emerges the complex nature of geomancy, whose original Arabic version had a prominent religious character and a close, albeit ambiguous, link with Islamic prophecy.
