GhiyÃÂth al-Dën ÿAlë ibn Ḥusayn ibn ÿAlë AmërÃÂn Iá¹£fahÃÂnë () 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 BadakhshÃÂn in the second half of the 15th century' CE. Little is known of him beyond the works attributed to him.
According to one recension of á¹¢aḥëfat al-nÃÂáºÂirën ('pages for the readers'), also known as Tuḥfat al-nÃÂáºÂirën ('gift for the readers') and Së à « shish á¹£aḥëfa ('thirty-six chapters'), GhiyÃÂth al-Dën 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 BadakhshÃÂn. In Beben's assessment, 'the á¹¢aḥëfat al-nÃÂáºÂirën is an important yet understudied work covering a series of topics related to Ismaili theology and doctrine, and is noteworthy for being the first Ismaili text known to have been composed within BadakhshÃÂn after NÃÂá¹£ir-i Khusraw (d. after 462/1070)', who seems to have been the person who introduced Ismailism to that region.
Most manuscripts of the á¹¢aḥëfat al-nÃÂáºÂirën attribute the text to the legendary për Sayyid SuhrÃÂb Walë, though Beben has suggested that the original person behind this figure might himself have been GhiyÃÂth al-Dën.
The date of composition of the work is usually stated to be 856/857 AH/1452âÂÂ1453 CE. As of 2022, thirteen manuscripts of the text were known (two copied from the 1960 printed edition); the oldest manuscript was copied in dated 1137/1725.
