Ferdowsi; Reviver of Persian language
Abolqasem Ferdowsi was born in 940 and laid to rest in 1020 AD in Tous, near Mashhad, the capital of Khorasan Razavi Province.
The Persian language and Ferdowsi's Shahnameh have had a long and inseparable connection with each other for centuries.
The well-known poet can be called a reviver of the Persian language, and Shahnameh, consisting of 50,000 verses, can be considered proof of Iranian identity.
Ferdowsi wrote one of the essential Iranian literary works, Shahnameh, which played a significant role in the revival of the Persian language and the spread of its literature.
Ferdowsi began his epic poem in 977 and took 33 years to complete it. The result of his work is the world's longest epic poem written by a single author; it is twice as long as Homer's 'Iliad' and 'Odyssey' combined. It was written at a time when modern Persian had started to thrive and the structures and standards for the language were being set.
