Year 298 (CCXCVIII) was a common year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Faustus and Gallus (or, less frequently, year 1051 Ab urbe condita). The denomination 298 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.
