At the time, it was known as the Year of the Consulship of Messalla and Suetrius (or, less frequently, year 967 Ab urbe condita). The denomination 214 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.
