Rawda-yi taslim (tasavvurat)

Nasir al-Din Tusi (d. 672/1274) was an influential philosopher, theologian, mathematician and astronomer, besides being the first director of the famous observatory at Maraghah near Tabriz as well as a man of politics. Author of a large number of scholarly works, he is especially famous for such treatises as his Tajrid al-i?tiqad on theology, the Zij-i Ilkhani on astronomy, the Hall mushkilat al-Isharat, his influential commentary on Avicenna's (428/1037) Kitab al-isharat wal-tanbihat on philosophy and logic, and his Akhlaq-i Nasiri on ethics. Tusi spent at least half of his academic and political life among the Nizari branch of the Ismailis, first in Quhistan in eastern Iran, and then in Alamut in the north and other Ismaili strongholds. The Persian work published here originated as a lecture series on Nizari Ismaili doctrine, given by Tusi in Alamut. The edition is a much improved version of the one by Ivanov, based on better manuscripts, unavailable to him.
