Muḥammad b. Aḥmad Abū al-‘Uqūl was a court astronomer for al-Malik al-Mu'ayyad Dāwūd and flourished around 1300 CE. His masterful set of astronomical tables (zīj) al-Mukhtār min al-azyāj is preserved in the British Library and is now available to view and download at the QDL.
The historian David King recognized the importance of this text since it copied a number of tables from the earlier zīj of Ibn Yūnus. There are 45 chapters . Below I attach the first two pages, followed by a table showing the coordinates of towns, including those in Yemen.
