He creatively uses what are now known as the `Urḍī lemma and the Ṭūsī couple to achieve combinations of uniform, circular motions (as required by ancient physics for motions in the heavens) that resolve the irregular motions resulting from Ptolemy’s equant for Mercury and from his choice of the center of the universe as the reference point of motion for the Moon’s eccentric orb.

These studies included the “General Principles” of Ibn Sīnā’s Canon of Medicine as well as Sufi mysticism. At Marāgha his most prominent teacher was Naṣīr al-Dīn al-Ṭūsī but he also studied with Najm al-Dīn al-Kātibī and `Urḍī. Sometime after leaving Marāgha, he traveled to Anatolia and studied in Konya, and was appointed chief judge in Malaṭya and Siwās. Circa 1290, Shīrāzī retired to Tabrīz.; Students included: Kamāl al-Dīn al-Fārisī (d. 1320), known for his work on optics (Tanqīḥ al-manāẓir), and Niẓām al-Dīn al-Nīsābūrī (d. 1329/30), a Qur’ān commentator and astronomer. Shīrāzī wrote 3 major works in theoretical astronomy: the Nihāyat al-idrāk fī dirāyat al-aflāk (The highest attainment in comprehending the orbs; completed 1281); al-Tuḥfa al-shāhiyya (The imperial gift; completed 1285); and Fa`alta fa-lā talum (You’ve done it so don’t blame [me]), a supercommentary on the Tadhkira fī `ilm al-hay’a by Ṭūsī.
