Who narrated Shahnameh even before Ferdowsi Tusi?

The Shahnameh, or 'Book of Kings', is the national epic of Iran, primarily authored by Ferdowsi Tusi. However, the monumental task of compiling Iran's mythical and historical past began before him. Daqiqi Tusi was an earlier Persian poet who undertook this project, composing approximately 1,000 verses, mainly focusing on the Zoroastrian period, before his untimely death. Ferdowsi later incorporated Daqiqi's work into his own comprehensive Shahnameh. Masud Saad Salman, Farrukhi Sistani, and Rudaki Samarqandi were significant Persian poets, but they were not involved in the early narration or compilation of the Shahnameh in the same capacity as Daqiqi.
