The Crisis of the Fourteenth Century has been regarded as a turning-point in world history, but it has typically only been approached from a European perspective. This volume expands that view by focusing on Asia and the Middle East (Afro-Eurasia) and by including environmental approaches that recognise the shifts in the Eurasian socio-ecological regime from the Medieval Climate Anomaly to the Little Ice Age. It therefore positions this period of history within three interrelated contexts – climate change, political upheaval outside Europe and a transcontinental pandemic – making historical connections typically not considered in studies of the Crisis.Bringing together thus-far neglected topics and case studies, and based on new sources and palaeo-scientific data, this book analyses the Crisis through an interdisciplinary lens. This intersection of climatology, environmental studies and history adds a long-awaited global dimension to the existing scholarship.

This book provides a critical edition, translation, and study of the version of Euclid’s treatise made by Thābit ibn Qurra, which is the earliest Arabic version that we have in its entirety. This monograph study examines the conceptual differences between the Greek and Arabic versions of the treatise, beginning with a discussion of the concept of "given" as it was developed by Greek mathematicians. This is followed by a short account of the various medieval versions of the text and a discussion of the manuscripts used in this volume. Finally, the Arabic text and an English translation are provided, followed by a critical commentary.
