387 BC

Year 387 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Tribunate of Papirius, Fidenas, Mamercinus, Lanatus and Poplicola (or, less frequently, year 367 Ab urbe condita). The denomination 387 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.
