Arch of Constantine (Rome)

Year 315 (CCCXV) was a common year starting on Saturday of the Julian calendar. At the time, it was known in Rome as the Year of the Consulship of Constantinus and Licinianus (or, less frequently, year 1068 Ab urbe condita). The denomination 315 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.
