The year 504 BC was a year of the pre-Julian Roman calendar. In the Roman Empire it was known as the Year of the Consulship of Poplicola and Tricipitinus (or, less frequently, year 250 Ab urbe condita). The denomination 504 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.
