AD 121

Year 121 (CXXI) was a common year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Verus and Augur. The denomination 121 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. ^{Marcus Aurelius, Roman emperor (d. 180)}
