Risālat ithbāt al-ʿaql al-mujarrad-i khwāja-yi Nasīr al-Dīn Ṭūsī va shurūḥ-i ān /
:
Naṣīr al-Dīn Ṭūsī (d. 672/1274) was an influential philosopher, theologian, mathematician and astronomer, besides being the first director of the famous observatory at Marāghah near Tabriz as well as a man of politics. The author of a large number of scholarly works, he is especially famous for such treatises as his Tajrīd al-iʿtiqād on theology; the Zīj-i Īlkhānī on astronomy; the Ḥall mushkilāt al-Ishārāt ; his influential commentary on Avicenna's (428/1037) Kitāb al-ishārāt wal-tanbīhāt on philosophy and logic; and his Akhlāq-i Nāṣirī on ethics. In the brief Arabic treatise that is the subject of this publication, Ṭūsī proves that there is a separate intellect in which all contingent being is semperternally represented, unchanging, as a kind of 'interface' between God and the human mind ( dhihn ). Even though this treatise is extremely short, it certainly had an impact, as is clear from the variety of critical reactions in the commentaries and glosses published alongside it in this volume.

Al-Muqniʿ fi ʼl-ḥisāb al-Hindī /
:
Abu ʼl-Ḥasan Nasawī was a mathematician and geometer of the 5th/11th century. He was a contemporary of Bīrūnī (d. 440/1048) and a student of Avicenna (d. 428/1037). Naṣīr al-Dīn Ṭūsī (d. 672/1274) mentions him in his works and so do others. Nasawī became known in the west through the publications of Franz Woepcke in the nineteenth century. Born in Rayy, Nasawī worked for the Buyid ruler Majd al-Dawla (d. 420/1029) and later for Sharaf al-Dawla, vizier to the Buyid ruler of Baghdad, Jalāl al-Dawla (d. 435/1044). In Nasawī's time, there were three types of arithmetic: finger-counting as used in business, a sexagesimal sytem with numbers denoted by letters of the Arabic alphabet, and an Indian system of numerals and fractions with decimal notation. The present work is about the Indian system and treats of four classes of numbers in four separate sections. This is Nasawī's own Arabic reworking of the Persian original, now lost.
