355 BC explained

Year 355 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Peticus and Poplicola (or, less frequently, year 399 Ab urbe condita). The denomination 355 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.
