King Odaenathus (totius Orientis imperator)

Year 266 (CCLXVI) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Gallienus and Sabinillus (or, less frequently, year 1019 Ab urbe condita). The denomination 266 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.
