Ferdowsi

Abu ʾl-Qasim Ferdowsi Tusi (c. 940 – 1020), commonly known as Ferdowsi, was a Persian poet. He wrote the "Shahnameh" ("The Book of Kings"), a monumental epic relating the history of Persia from the creation of the world until the Islamic conquest.

During the early 16th century, the Assassin Ezio Auditore da Firenze retrieved a copy of this book which Niccolò Polo had hidden two centuries earlier on the Harbor of Theodosius docks in Constantinople.
