Ghiyāth al-Dīn ʿAlī ibn Ḥusayn ibn ʿAlī Amīrān Iṣfahānī () was a fifteenth-century Persian physician and scientist from Isfahan, Iran. He was, in the words of Daniel Beben, 'a polymath in the service of several of the Timurid governors of Badakhshān in the second half of the 15th century' CE. Little is known of him beyond the works attributed to him.
Works
- Asrār al-ḥurūf (870 AH/1465–1466 CE), dedicated to then governor of Badakhshān Abū Bakr, son of the Timurid ruler Abū Saʿīd Mirza.
- Dānish-nāma-i jahān, dedicated to Sulṭān Maḥmūd Mirza, also a son of Abū Saʿīd Mirza, governor of Badakhshān from 873/1469. This is Ghiyāth al-Dīn's best known work, a Persian encyclopedia of the natural sciences, concerned with meteorology, mineralogy, botany, and anatomy.
- Durrat al-misāḥa (890 AH/1485 CE), on measurements and geometry, likewise dedicated to Sulṭān Maḥmūd Mirza.
- Khulāṣat al-tanjīm va burhān al-taqvīm, on astronomy.
- Maʿārif al-taqvīm, also known as Nujūm, also on astronomy.
- A small treatise on foodstuffs, in table format, is preserved in the National Library of Medicine collection.
Ṣaḥīfat al-nāẓirīn
According to one recension of Ṣaḥīfat al-nāẓirīn ('pages for the readers'), also known as Tuḥfat al-nāẓirīn ('gift for the readers') and Sī ū shish ṣaḥīfa ('thirty-six chapters'), Ghiyāth al-Dīn also composed that text; Daniel Beben has accepted this attribution, arguing that its explicit Ismailism, which would have been unacceptable to the Timurids, implies that this text was composed before their conquest of Badakhshān.
