The Historia Augusta relates an incident where the supposed writer of Aurelian's biography had a discussion with Tiberianus, which has been traditionally dated to during his term as Urban Prefect: Junius Tiberianus, the prefect of the city, an illustrious man and one to be named only with a prefix of deep respect, took me up into his carriage, that is to say, his official coach.
There his mind being now at leisure, relaxed and freed from law-pleas and public business, he engaged in much conversation all the way from the Palatine Hill to the Gardens of Varius, his theme being chiefly the lives of the emperors.
When I replied that I had read none in Latin, though several in Greek, that revered man poured forth in the following words the sorrow that his groan implied: "Shall the Deified Aurelian, that most famous of princes, that most firm of rulers, who restored the whole world to the sway of Rome, be unknown to posterity?
And yet, if I am not mistaken, we possess the written journal of that great man and also his wars recorded in detail in the manner of a history, and these I should like you to procure and set forth in order, adding thereto all that pertains to his life.
