Most of what is known of Cursor's life comes from the monumental "History of Rome" written by Livy during the reign of Augustus. Livy portrayed Cursor as an invincible hero, who avenged the humiliation of the Caudine Forks in 321 BC, when the Roman army had to pass under the yoke. In a famous digression, he even wrote that had Alexander the Great turned his army against Rome, he would have met his match with Cursor. With this narrative, Livy participated in the Roman propaganda sponsored by Augustus, which idealised several figures of the first part of the Republic. As a result, it is difficult to separate his life from the fiction elaborated by later Roman authors.
