As one of the great literatures of mankind the Persian literature has its roots in surviving works in Old Persian or Middle Persian dating back as far as 522 BCE, the date of the earliest surviving Achaemenid inscription, the Bisotun Inscription.
The bulk of the surviving Persian literature, however, comes from the times following the Islamic conquest of Persia circa 650 CE.
Panegyric masters such as Rudaki were known for their love of nature, their verse abounding with evocative descriptions.
Through these courts and system of patronage emerged the epic style of poetry, with Ferdowsi's Shahnama at the apex.
Khorasani style, whose followers mostly were associated with Greater Khorasan, is characterized by its supercilious diction, dignified tone, and relatively literate language.
The chief representatives of this lyricism are Asjadi, Farrukhi Sistani, Unsuri, and Manuchehri.
However, some essays in Pahlavi such as "Ayin-e name nebeshtan" (Principles of Writing Book) and "Bab-e edteda’I-ye" (Kalileh o Demneh) have been considered as literary criticism (Zarrinkoub, 1959).
Most of what remains consists of the royal inscriptions of Achaemenid kings, particularly Darius I (522–486 BC) and his son Xerxes.
Some works of Sassanid geography and travel also survived albeit in Arabic translations.
No single text devoted to literary criticism has survived from pre-Islamic Persia.
The tradition of royal patronage began perhaps under the Sassanid era and carried over through the Abbasid and Samanid courts into every major Persian dynasty.
The Qasida was perhaps the most famous form of panegyric used, though quatrains such as those in Omar Khayyam's Ruba'iyyat are also widely popular.
By glorifying the Iranian historical past in heroic and elevated verses, he and other notables such as Daqiqi and Asadi Tusi presented the "Ajam" with a source of pride and inspiration that has helped preserve a sense of identity for the Iranian peoples over the ages.
