The 10th-century text is a universal history, spanning a period beginning with the dawn of creation through to the Islamic age.
While the author claims the book is a Persian translation of al-Tabari's History of the Prophets and Kings, it is actually an independent work.
[1][2] The literary style deviates from that of earlier Pahlavi and Middle Persian works composed in the Sasanian Empire.
Various manuscripts of this book are today available in the libraries of Iran, India, Turkey and Europe.
The book was translated into Persian language at the order of Mansur ibn Nuh, the Samanid amir.
