Mediaevalia Lovaniensia 39Communication leads to an evolution of knowledge, and the free exchange of knowledge leads to fresh findings. In the Middle Ages things were no different. The inheritance of ancient knowledge deeply influenced medieval thought. The writings of ancient Greek philosophers such as Aristotle reached medieval readers primarily through translations. Translators made an interpretation of the source-text, and their translations became the subject of commentaries. An understanding of the complex web of relations among source-texts, translations, and commentaries reveals how scientific thinking evolved during the Middle Ages. Aristotle's Problemata, a text provoking various questions about scientific and everyday topics, amply illustrates the communication of ideas during the transition between antiquity and the Renaissance.

The Problemata physica is the third longest work in the corpus Aristotelicum, but among the least studied. It consists of 38 books, over 900 chapters, covering a vast range of subjects, including medicine and music, sex and salt water, fatigue and fruit, animals and astronomy, moderation and malodorous things, wind and wine, bruises and barley, voice and virtue. Aristotelian Problemata Physica: Philosophical and Scientific Investigations consists of 21 essays by scholars of ancient Greek philosophy and science. These essays shed light on this mysterious work, providing insights into the nature of philosophical and scientific inquiry in the Lyceum during Aristotle’s life and especially in the years following his death.

Psychology and the Other Disciplines looks at how Aristotelian psychology developed from the medieval to the early modern period, by studying its interactions with the other philosophical disciplines, medicine, and theology.

An interdisciplinary study of hair through the art, philosophy, and science of fifteenth-century Florence. In this innovative cultural history, hair is the portal through which Emanuele Lugli accesses the cultural production of Lorenzo il Magnifico’s Florence. Lugli reflects on the ways writers, doctors, and artists expressed religious prejudices, health beliefs, and gender and class subjugation through alluring works of art, in medical and political writings, and in poetry. He considers what may have compelled Sandro Botticelli, the young Leonardo da Vinci, and dozens of their contemporaries to obsess over braids, knots, and hairdos by examining their engagement with scientific, philosophical, and theological practices. By studying hundreds of fifteenth-century documents that engage with hair, Lugli foregrounds hair’s association to death and gathers insights about human life at a time when Renaissance thinkers redefined what it meant to be human and to be alive. Lugli uncovers overlooked perceptions of hair when it came to be identified as a potential vector for liberating culture, and he corrects a centuries-old prejudice that sees hair as a trivial subject, relegated to passing fashion or the decorative. He shows hair, instead, to be at the heart of Florentine culture, whose inherent violence Lugli reveals by prompting questions about the entanglement of politics and desire.

Mediaevalia Lovaniensia 40Medieval translators played an important role in the development and evolution of a scientific lexicon. At a time when most scholars deferred to authority, the translations of canonical texts assumed great importance. Moreover, translation occurred at two levels in the Middle Ages. First, Greek or Arabic texts were translated into the learned language, Latin. Second, Latin texts became source texts themselves, to be translated into the vernaculars as their importance across Europe started to increase.The situation of the respective translators at these two levels was fundamentally different: whereas the former could rely on a long tradition of scientific discourse, the latter had the enormous responsibility of actually developing a scientific vocabulary. The contributions in the present volume investigate both levels, greatly illuminating the emergence of the scientific terminology and concepts that became so fundamental in early modern intellectual discourse. The scientific disciplines covered in the book include, among others, medicine, biology, astronomy, and physics.

In his Problemata, Aristotle provided medieval thinkers with the occasion to inquire into the natural causes of the sexual desires of men to act upon or be acted upon by other men, thus bringing human sexuality into the purview of natural philosophers, whose aim it was to explain the causes of objects and events in nature. With this philosophical justification, some late medieval intellectuals asked whether such dispositions might arise from anatomy or from the psychological processes of habit formation. As the fourteenth-century philosopher Walter Burley observed, "Nothing natural is shameful." The authors, scribes, and readers willing to "contemplate base things" never argued that they were not vile, but most did share the conviction that they could be explained. From the evidence that has survived in manuscripts of and related to the Problemata, two narratives emerge: a chronicle of the earnest attempts of medieval medical theorists and natural philosophers to understand the cause of homosexual desires and pleasures in terms of natural processes, and an ongoing debate as to whether the sciences were equipped or permitted to deal with such subjects at all. Mining hundreds of texts and deciphering commentaries, indices, abbreviations, and marginalia, Joan Cadden shows how European scholars deployed a standard set of philosophical tools and a variety of rhetorical strategies to produce scientific approaches to sodomy.

A Choice Outstanding Academic Title, 2008 A Cultural History of Animals in the Medieval Age investigates the changing roles of animals in medieval culture, economy and society in the period 1000 to 1400. The period saw significant changes in scientific and philosophical approaches to animals as well as their representation in art. Animals were omnipresent in medieval everyday life. They had enormous importance for medieval agriculture and trade and were also hunted for food and used in popular entertainments. At the same time, animals were kept as pets and used to display their owner's status, whilst medieval religion attributed complex symbolic meanings to animals. A Cultural History of Animals in the Medieval Age presents an overview of the period and continues with essays on the position of animals in contemporary symbolism, hunting, domestication, sports and entertainment, science, philosophy, and art.
