The four Tetrarchs, Venice

Map of the Roman Empire under the Tetrarchy (293)

Year 293 (CCXCIII) 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 Valerius and Valerius (or, less frequently, year 1046 Ab urbe condita). The denomination 293 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.
