Empress Egnatia Mariniana
Year 254 (CCLIV) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Valerianus and Gallienus (or, less frequently, year 1007 Ab urbe condita). The denomination 254 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.
