Gardizi
Abū Saʿīd ʿAbd-al-Ḥayy ibn Żaḥḥāk ibn Maḥmūd Gardīzī (Persian: ابوسعید عبدالحی بن ضحاک بن محمود گردیزی), better known as Gardizi (گردیزی), was an 11th-century Persian[1] historian and official, who is notable for having written the Zayn al-akhbar, one of the earliest history books written in New Persian.[1] Gardizi started his career as an official of the Ghaznavid monarch Mahmud of Ghazni (r. 998–1030), and was an eyewitness to many of the events that occurred under the latter.[2] In his Zayn al-akbar, Gardizi took a dispassionate view of history which was fairly remarkable for its time.[1] It consisted of a history of the pre-Islamic kings of Iran, Muhammad and the Caliphs until the year 1032.Included is a history of the Arab conquest of Khorasan, which it is believed Gardizi was using al-Sallami as a source.
