The Astronomical Tables of Ulugh Beg

The Zīj-i-Ṣultānī, also known as the Zīj-i-Gurgānī, is one of the last great Islamic collections of astronomical tables. More than 200 copies, in Persian, Arabic and Turkish, are known to exist and the work was of great influence on late-Islamic astronomy.

According to the foreword the tables were compiled by Ulugh Beg himself with the help of Ghiyāth al-Dīn Jamshīd ibn Masʿūd al-Kāshī (d. 1429?) and Ṣalāḥ al-Dīn Mūsā ibn Muḥammad ibn Maḥmūd Qāḍī-zāda al-Rūmī (c. 1359-after 1440) and after their death by ʿAlā al-Dīn ʿAlī ibn Muḥammad al-Qūshjī (c. 1402-1474/75).

The Zīj-i-Ṣultānī contains the following:
