NOTOC Year 391 (CCCXCI) was a common year starting on Wednesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Tatianus and Symmachus (or, less frequently, '*year 1144 *Ab urbe condita'''''). The denomination 391 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.
