In Synchrony with the Heavens, Volume 2 Instruments of Mass Calculation : (Studies X-XVIII) /
:
This is the first investigation of one of the main interests of astronomy in Islamic civilization, namely, timekeeping by the sun and stars and the regulation of the astronomically-defined times of Muslim prayer. The study is based on over 500 medieval astronomical manuscripts first identified by the author, now preserved in libraries all over the world and originally from the entire Islamic world from the Maghrib to Central Asia and the Yemen. The materials presented provide new insights into the early development of the prayer ritual in Islam. They also call into question the popular notion that religion could not inspire serious scientific activity. Only one of the hundreds of astronomical tables discussed here was known in medieval Europe, which is one reason why the entire corpus has remained unknown until the present. A second volume, also to be published by Brill, deals with astronomical instruments for timekeeping and other computing devices.

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.

Zīj-i Yamīnī /
:
In Islamic science, a zīj is an astronomical handbook made up of tables and text. Between the 2nd/8th and 13th/19th centuries, over 200 such works were written, many of them lost. Famous zīj are al-Zīj al-Ṣābiʾ by al-Battānī (ca 300/900), al-Qānūn al-Masʿūdī by al-Bīrūnī (421/1030), and Naṣīr al-Dīn al-Ṭūsī's (d. 672/1274) Zīj-i Īlkhānī . The Zīj-i Yamīnī published in facsimile here was compiled in Ghazna in 511/1156 by a certain Muḥammad al-Ḥaqāʾiqī and dedicated to the Ghaznavid ruler Bahrāmshāh b. Masʿūd b. Maḥmūd (reg. 511-552/1117-1157). It is the third oldest zīj in Persian, after the Zīj-i mufrad of Muḥammad b. Ayyūb Ṭabarī (485/1092) and the Persian translation of Kūshyār b. Labbān Gīlānī's (fl. ca. 390/1000) Arabic al-Zīj al-jāmiʿ by Muḥammad b. ʿUmar Munajjim-i Tabrīzī in 483/1090. Al-Ḥaqāʾiqī based himself on the works of others, notably al-Battānī's al-Zīj al-Ṣābiʿ , whose data he then recalculated for the city of Ghazna where necessary. Good example of early scientific Persian.
