358 BC

Year 358 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Ambustus and Proculus (or, less frequently, year 396 Ab urbe condita). The denomination 358 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.
