503 BC

The year 503 BC was a year of the pre-Julian Roman calendar. In the Roman Empire it was known as the Year of the Consulship of Lanatus and Tubertus (or, less frequently, year 251 Ab urbe condita). The denomination 503 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.
