178 BC

Year 178 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Brutus and Vulso (or, less frequently, year 576 Ab urbe condita). The denomination 178 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.
