Safarnāma or Safarnāmé (Persian: سفرنامه), also spelled as safarnameh, is a travel literature written during the 11th century by Nasir Khusraw (1003-1077). It is also known as the Book of Travels and was a work that shaped the future of classical Persian travel writing.
It is an account of Khusraw's seven year journey through the Islamic world. He initially set out on a Hajj, the obligatory Pilgrimage to Mecca. Departing in 1046, Khusraw took a less than direct route, heading north toward the Caspian Sea. Throughout his travels he kept a minutely detailed journal which clearly describes many facets of life in the Islamic world of the 11th Century.
