Jahān-i dānish /

: Sharaf al-Din Mas'ūdi (6th/12th cent.) was a philosopher, astronomer, mathematician and logician. A native of Marw, he spent a large part of his life in Bukhara and Samarqand, Transoxiana. In Bukhara he had a number of debates with the philosopher and theologian Fakhr al-Dīn Rāzī (d. 606/1210), described in the latter's Munāẓarāt jarat fī bilād Mā warāʾ al-nahr . From among his philosophical works, his critical notes to Avicenna's (d. 428/1037) al-Ishārāt wal-tanbīhāt deserve special mention. In the sciences, he wrote a work on astronomy and geography called al-Kifāya fī ʿilm al-hayʾa . In the introduction to this work he explains that he composed it at the request of a friend and that it is based on the works of others, among then Ibn al-Haytham (d. ca. 432/1040-41) and Kushyār b. Labbān (fl. late 4th/10th cent.). Afterwards, he translated it into Persian-this time without mentioning his sources-calling it Jahāni- dānish , published in this volume.

Volkstümliche Astronomie im islamischen Mittelalter : zur Bestimmung der Gebetszeiten und der Qibla bei al-Aṣbaḥī, Ibn Raḥīq und al-Fārisī /

: 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.
