At the time, it was known as the Year of the Consulship of Eggius and Aelianus (or, less frequently, year 937 Ab urbe condita). The denomination 184 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
