Battle of Strasbourg (Argentoratum)
Year 357 (CCCLVII) was a common year starting on Wednesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Constantius and Iulianus (or, less frequently, year 1110 Ab urbe condita). The denomination 357 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.
