Ibn Abī al‐Shukr (Arabic: ابن ابي الشكر; d. 1283 CE) was an Andalusī astronomer, astrologer and mathematician of the Islamic Golden Age. He belonged to the group of astronomers associated with the Maragheh observatory, most notably Nasir al-Din al-Tusi. In astronomy, Ibn Abi al-Shukr carried out a large‐scale project of systematic planetary observations, which led to the development of several new astronomical parameters.
His known works on astronomy include:
- Tasṭīḥ al‐asṭurlāb: a description of the construction and use of the astrolabe.
- Maqāla fī istikhrāj taʿdīl al‐nahār wa saʿat al‐mashriq wa‐ʾl‐dāʾir min al‐falak bi‐ṭarīq al‐handasa: a description of the geometrical methods used to determine the meridian line, the rising amplitude, and the revolution of the sphere.
- Risālat al‐Khaṭā wa‐ʾl‐īghūr: a chronological work on the Chinese and Uighur calendars, which was later translated from Arabic and Persian into Chinese.
- Three zijes:
- Tāj al‐azyāj wa‐ghunyat al‐muḥtāj (The crown of astronomical handbooks), also known as Al‐muṣaḥḥaḥ bi‐adwār al‐anwār maʿa al‐raṣad wa‐ʾl‐iʿtibār.
- Adwār al‐anwār madā al‐duhūr wa‐ʾl‐akwār: contains results of the astronomical observations he carried out in Marāgha.
- ʿUmdat al‐ḥāsib wa‐ghunyat al‐ṭālib
- Three commentaries on Ptolemy's Almagest:
- Talkhīṣ al‐Majisṭī (Compendium of the Almagest): based on his observations carried out between 1264 and 1275 CE.
- Khulāṣat al‐Majisṭī (Summary of the Almagest)
- Muqaddimāt tataʿallaq bi‐ḥarakāt al‐kawākib (Prolegomena on the motion of the stars): contains five geometric premises on the planetary motions in the Almagest.
Ibn Abī al‐Shukr's astrological works were mainly devoted to horoscopes and planetary conjunctions used to tell the future.
