Year 248 (CCXLVIII) was a leap year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Philippus and Severus (or, less frequently, year 1001 Ab urbe condita). The denomination 248 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.
