Nicole Oresme was one of the most original and influential thinkers of the fourteenth century. He is best known for his mathematical discoveries, his economic theories, as well as his vernacular translations of cosmological and ethical texts that were undertaken at the request of King Charles V. This volume sheds light on the beginning of Oresme's scientific activity at the University of Paris (ca. 1340 – ca. 1350), a period of his intellectual career about which little is known. Over the course of this decade, Oresme lectured on many Aristotelian texts on natural philosophy, such as the Physics, On the Heavens, On generation and corruption, Meteorology, and On the Soul. Oresme's commentaries on Aristotle's Meteorology count among his only unpublished texts. This volume presents the first critical edition of books I-II.10 of the second redaction of Oresme's Questions on Meteorology. The edition is preceded by a historical and philological introduction that discusses the context of Oresme’s scientific career and examines the manuscript tradition.

The open access publication of this book has been published with the support of the Swiss National Science Foundation. Nicole Oresme, a mathematician, philosopher, and theologian, stood as one of the most original and influential thinkers of the Late Middle Ages. This volume presents the critical edition of Oresme's earliest work, his first cycle of lectures on Aristotle's Meteorology (1346). Transcribed directly by one of his students at Paris Arts Faculty, this text explores problems of physics, cosmology, geology, and optics, providing invaluable insights into late medieval philosophy of nature.

Few figures of the Middle Ages command the attention of so many modern disciplines as Robert Grosseteste (c. 1170-1253). Theology, Philosophy, History, and Science are all areas which his life and thought continue to have significance and to inspire re-interpretation. Accompanied by a series of original commentaries, this new edition of Grosseteste's work, with English translation, draws together the perspectives of modern scientists and medieval specialists. Volume I of a six volume series, Knowing and Speaking presents two of the earliest of Grosseteste's works, the treatises On the Liberal Arts and On the Generation of Sounds. These are accompanied by a significant Middle English treatise on the Seven Liberal Arts whose anonymous fifteenth-century author translated and excerpted passages from Grosseteste's treatises in a re-imagining of their structure and function. Each work is treated separately within the volume, which is constructed in three parts. On the Liberal Arts sets Grosseteste's thoughts on the arts subjects and emphasises moral concerns about the purpose of learning. On the Generation of Sounds builds on the theories and statements of On the Liberal Arts in connection to the production of sound, elaborating the earlier position, relating the generation of sounds to human vocal and speech production.

For the first time, the reader can have a synoptic view of the reception of Pythagoras and Pythagoreanism in the Middle Ages and the Renaissance, East and West, in a multicultural perspective. All the major themes of Pythagoreanism are addressed, from mathematics, number philosophy and metaphysics to ethics and religious thought.

"Robert Grosseteste's treatise De colore is presented here in an authoritative new critical edition, with translation, commentary on its context, and a functional analysis from the perspective of modern science."--P. [i].
