It was written by Keikavus, the Ziyarid ruler of parts of Tabaristan, and was dedicated to his son Gilanshah. The belles-lettres was written in 44 chapters and outlines princely education, manners, and conduct in ethical didactic prose.

The Egyptian National Library and Archives keeps a copy in Old Anatolian Turkish, written during the reign of Süleyman of Germiyan. One of the earliest remaining copies of this work is one dating from 1450, translated into Turkish by Mercimek Ahmed on the orders of the Ottoman Sultan Murad II.
