The year 501 BC was a year of the pre-Julian Roman calendar. In the Roman Empire it was known as the Year of the Consulship of Auruncus and Lartius (or, less frequently, year 253 Ab urbe condita). The denomination 501 BC for this year has been used since the early medieval period, when the Anno Dominicalendar era became the prevalent method in Europe for naming years.
