Qushjī’s Risālah dar `ilm-i hay’a (Persian), written in Samarqand in 1458, was commonly used as a teaching text; there exist over 80 manuscript copies of it in libraries throughout the world. It was also translated into Turkish. Two commentaries were written on it, one by Muṣliḥ al-Dīn al-Lārī (d. 1571), the other by an anonymous author. Lārī’s was widely taught in Ottoman madrasas. Qushjī’s Risāla was also translated into Sanskrit. Also, Qushjī’s al-Fatḥiyya fī `ilm al-hay’a, which was presented to Sultan Mehmed in 1473, is an enlarged version of this work in Arabic.
