Year 11 (XI) was a common year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Lepidus and Taurus (or, less frequently, year 764 Ab urbe condita). The denomination 11 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. The Year XI (eleven) is also a year in the French Revolutionary Calendar.
