# 478 BC

Year 478 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Mamercus and Structus (or, less frequently, year 276 Ab urbe condita). The denomination 478 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.
