Ferdowsi
Hakim Abu ʾl-Qasim Ferdowsi Tusi (940–1020 CE), or Firdawsi, was a highly revered Persian poet and the author of the epic of Shahnameh - the Persian "Book of Kings" - which is the world's longest epic poetry created by a single poet, and the national epic of Iran and the Persian speaking world. Having drafted the Shahnameh under patronage of the Samanid and the Ghaznavid courts of Persia, Ferdowsi is celebrated as one of the most influential Persian poets of all time, and an influential figure in Persian literature.
