Farhād Tarāsh is a long smoothed rock surface on the Mount Behistun from ancient Persia. It is located near the Behistun Inscription. Its height is around 36 meters and its width is around 200 meters. The work is registered as a national heritage in Iran. The actual date of the work is not known. Some scholars including Ernst Herzfeld believed that it was carved by Darius the Great and that he planned to write his will on it. Others such as Jackson have suggested that Darius carved this place in order to write an account of his wars and campaigns. It is also suggested that this work is carved by Khosrow II in order to record an important historical event. Recently, the scholars have suggested that it was just a stone mine.
