458 BC

Year 458 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Rutilus and Carvetus (or, less frequently, year 296 Ab urbe condita). The denomination 458 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.
