Abū Saʿīd ʿAbd-al-Ḥayy ibn Żaḥḥāk ibn Maḥmūd Gardīzī, commonly known as Gardizi, was a prominent Persian historian and geographer of the eleventh century. His most notable work, the Zayn al-akhbar, stands as one of the earliest historical texts composed in New Persian, marking a significant contribution to the historiography of the region.
Little is documented about Gardizi's personal life, but it is believed he hailed from Gardiz in the Zamindawar region, as suggested by his nisba. His lineage traces back to his father, Zahhak, a name that was prevalent in that area. Gardizi's career began under the auspices of the Ghaznavid ruler Mahmud of Ghazni, during whose reign he witnessed numerous historical events.
In his Zayn al-akhbar, Gardizi adopted a notably objective perspective on history, which was quite exceptional for his time. The work encompasses a narrative of pre-Islamic Iranian kings, the life of Muhammad, and the Caliphs, extending up to the year one thousand thirty-two. Among its contents is a detailed account of the Arab conquest of Khorasan, likely drawing from the works of al-Sallami.
Furthermore, Gardizi's exploration of Turkish history was informed by sources such as Ibn Khordadbeh, Jayhani, and Ibn al-Muqaffa'. There is speculation that he may have been a student of the renowned scholar al-Biruni, as his writings also reflect knowledge of Indian festivals, showcasing the breadth of his scholarly pursuits.
