Year 457 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Pulvillus and Augurinus or Cincinnatus and Vibulanus (or, less frequently, year 297 Ab urbe condita). The denomination 457 BC 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.
