For the book Ab Urbe Condita by Livius, see Ab Urbe Condita (book). of the city (Rome) », which has traditionally been set to 753 BC. The phrase was used to identify the Roman year by a few Roman historians in antiquity. Writers in the Renaissance occasionally used AUC on Roman manuscripts they published due to the misconception that the Romans themselves usually numbered their years by this system. Modern historians have used it more than the Romans themselves did; for the Romans, it was common to enter a specific year by entering the names of the two who held the office of consul that year. The year of the emperor's inauguration was also used to identify the years, especially in the Byzantine Empire after 537 when Justinian I the Great ordered this practice.
