Year 499 BC was a year of the pre-Julian Roman calendar. In the Roman Empire, it was known as the Year of the Consulship of Aebutius and Cicurinus (or, less frequently, year 255 Ab urbe condita).[citation needed] The denomination 499 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.
