334

Year 334 (CCCXXXIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Optatus and Caesonius (or, less frequently, year 1087 Ab urbe condita). The denomination 334 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.
