The Alexandrian Summaries of Galen’s On Critical Days
Galen's impact on Islamic civilization, mainly on medicine but also on physics and philosophy, was enormous. His most important books were mediated through "summaries" which not only shortened, but in Galen's impact on Islamic civilization, mainly on medicine but also on physics and philosophy, was enormous. His most important books were mediated through "summaries" which not only shortened, but in some cases also revised Galenic teachings. Several versions of these summaries exist, and their appreciation is critical for a proper understanding of the development of medieval science. This book presents the first editions, translations, and studies of the remaining summaries to On Critical Days. In Galenic theory, fevers develop towards a crisis which will determine the fate of a patient. The cycle of crisis is known through observation, but the search for the cause leads Galen and his later interpreters into the fields of astrology, arithmology, and more.

Babylonian and Indian wisdoms in Islamicate culture
The interaction of Islamicate civilization with those civilizations that preceded it or were contemporaneous with it has focused for the most part on Hellenistic civilization, and the huge body of sci The interaction of Islamicate civilization with those civilizations that preceded it or were contemporaneous with it has focused for the most part on Hellenistic civilization, and the huge body of scientific and philosophical literature which was translated and absorbed in the first centuries after the appearance of Islam. This paper aims to present two small but much needed correctives to this understanding. In the first section I argue that the “Greek” astronomy that was translated into Arabic ought more correctly to be described as Greco-Babylonian astronomy. In the second I turn to India: not only was a great deal of Indian knowledge absorbed at the time of the great translation movement, we must recall that the exchanges with India carried on well beyond the early Abbasids. I illustrate these points with some new materials in the fields of medicine, philosophy, and alchemy.

The chapter on Rasāyana (Medications for Rejuvenation) in Miʿrāj al-duʿāʾ, a Shiʿite text from the 12th/18th century
Miʿrāj al-duʿāʾ wa-mirʾāt al-dawāʾ (“The Ascent of Prayer and the Mirror of Medication”) by Muḥammad ʿAlī al-Qazwīnī, a Shiʿite presumably working in eastern Iraq in the eighteenth century, gathers in Miʿrāj al-duʿāʾ wa-mirʾāt al-dawāʾ (“The Ascent of Prayer and the Mirror of Medication”) by Muḥammad ʿAlī al-Qazwīnī, a Shiʿite presumably working in eastern Iraq in the eighteenth century, gathers information on methods for rejuvenation and longevity from different traditions: traditional Islamic (mainly Shiʿite), Greek, and Indian. The last of these are a set of recipes for rasayanas, herbal and chemical recipes drawn from Indian sources. Though some rasayanas are mentioned in earlier Arabic treatises, the collection displayed in Miʿrāj al-duʿāʾ is by far the most extensive. Hardly any are mentioned in earlier Arabic texts. Miʿrāj al-duʿāʾ, then, contributes an important chapter to the ongoing interchange between India and the eastern Islamic world. Unlike the majority of treatises which deal with India, it is written in Arabic rather than Persian, though not a few loan words are employed. I present here an edition, translation, and analysis of the relevant chapter.

Isaac Israeli (the Elder): some interesting remarks on the Posterior Analytics in his Book on Fevers

Stern—makes some remarks that are of interest for the history of philosophy. Though these have not gone entirely unnoticed, they have not been discussed in any detail; the present communication seeks to do just that. The remarks consist of interpretations in a Pythagorean vein of some statements in Aristotle's Posterior Analytics, which, as far as I can determine, are original with Israeli.

Maimonides’ curious formulation of the 4th premise of the Mutakallimūn
Moses Maimonides alerts readers of his seminal Guide of the Perplexed that he has taken the greatest care in writing this book. As a result, readers have dissected almost every word or phrase in their Moses Maimonides alerts readers of his seminal Guide of the Perplexed that he has taken the greatest care in writing this book. As a result, readers have dissected almost every word or phrase in their attempt to ferret out the author’s true intent. But was every word chosen with such care? The late Herbert Davidson, until his recent passing the dean of Maimonidean scholars worldwide, challenged that belief. A passage from Maimonides’ presentation of the basic doctrines of the kalām, which seems to contain an extraneous technical term, may support Davidson’s claim. At the very least, a close examination reveals much about the problematics of translating and interpreting the Guide.

The Qurʾān commentaries of Šams al-Dīn al-Ḫuwayyī (583/1193-637/1247)

Scholars have suggested that al-Rāzī’s disciple Šams al-Dīn al-Ḫuwayyī may have contributed to the final tafsīr, but were unable to come to any definitive conclusions, partly because they had no tafsīr by al-Ḫuwayyī that could be used for comparison. In fact, we know of two commentaries of al-Ḫuwayyī: a section of his encyclopedia which displays explorations into seven selected suwar, and some snippets of a different tafsīr that are preserved by al-Suyūṭī. These two important sources are described in this notice. We also briefly mention some first-hand encounters of al-Ḫuwayyī with his master al-Rāzī, as they are reported in the former’s encyclopedia.

One-quarter of his short ethical-philosophical treatise, the Kalimāt wajīza, is given over to ‘ilm al-nafs. In this paper, I present an annotated translation of the second of the five chapters that make up that section of the treatise.
