Year 455 (CDLV) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Valentinianus and Anthemius (or, less frequently, year 1208 Ab urbe condita). The denomination 455 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.

• angry mob while fleeing Rome. A widespread panic occurs when many citizens hear the news that the Vandals
  are plundering the Italian mainland.
