This source book provides new information about a much neglected aspect of the scientific tradition of the Islamic Middle Ages, focusing on folk astronomy and its relations to religious duties (determination of the times of Muslim prayer and the direction towards the Kaaba in Mecca (Arabic qibla)).

This volume deals with the determination of the times of Muslim prayer and the direction towards the Kaaba in Mecca (Arabic qibla ) in a little known astronomical tradition of the Islamic Middle Ages. It presents an edition, translation, and explanation of selected chapters from three of the most important folk astronomical treatises, written by al-Aṣbaḥī (Yemen, 13th c.), Ibn Raḥīq (Hejaz, 11th c.), and al-Fārisī (Yemen, 13th c.). The first part introduces the authors and their works and describes the relevant religious and astronomical background. The second part comprises the edition of the selected - and now for the first time published - chapters of the three works and a German translation. The third part contains a lexicographical survey with basic astronomical, religious, and related information, and a commentary on each chapter. The fourth part gives an overview of the topics dicussed.

Two opposing views of the future in the Middle Ages dominate recent historical scholarship. According to one opinion, medieval societies were expecting the near end of the world and therefore had no concept of the future. According to the other opinion, the expectation of the near end created a drive to change the world for the better and thus for innovation. Close inspection of the history of prognostication reveals the continuous attempts and multifold methods to recognize and interpret God’s will, the prodigies of nature, and the patterns of time. That proves, on the one hand, the constant human uncertainty facing the contingencies of the future. On the other hand, it demonstrates the firm believe during the Middle Ages in a future which could be shaped and even manipulated. The handbook provides the first overview of current historical research on medieval prognostication. It considers the entangled influences and transmissions between Christian, Jewish, Islamic, and non-monotheistic societies during the period from a wide range of perspectives. An international team of 63 renowned authors from about a dozen different academic disciplines contributed to this comprehensive overview.

About a millennium ago, in Cairo, an unknown author completed a large and richly illustrated book. In the course of thirty-five chapters, this book guided the reader on a journey from the outermost cosmos and planets to Earth and its lands, islands, features, and inhabitants. This treatise, known as The Book of Curiosities, was unknown to modern scholars until a remarkable manuscript copy surfaced in 2000. Lost Maps of the Caliphs provides the first general overview of The Book of Curiosities and the unique insight it offers into medieval Islamic thought. Opening with an account of the remarkable discovery of the manuscript and its purchase by the Bodleian Library, the authors use The Book of Curiosities to re-evaluate the development of astrology, geography, and cartography in the first four centuries of Islam. Their account assesses the transmission of Late Antique geography to the Islamic world, unearths the logic behind abstract maritime diagrams, and considers the palaces and walls that dominate medieval Islamic plans of towns and ports. Early astronomical maps and drawings demonstrate the medieval understanding of the structure of the cosmos and illustrate the pervasive assumption that almost any visible celestial event had an effect upon life on Earth. Lost Maps of the Caliphs also reconsiders the history of global communication networks at the turn of the previous millennium. It shows the Fatimid Empire, and its capital Cairo, as a global maritime power, with tentacles spanning from the eastern Mediterranean to the Indus Valley and the East African coast. As Lost Maps of the Caliphs makes clear, not only is The Book of Curiosities one of the greatest achievements of medieval mapmaking, it is also a remarkable contribution to the story of Islamic civilization that opens an unexpected window to the medieval Islamic view of the world.
