124 BC

Year 124 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Longinus and Calvinus (or, less frequently, year 630 Ab urbe condita) and the Fifth Year of Yuanshuo. The denomination 124 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.
