Year 52 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Pompeius and Scipio (or, less frequently, year 702 Ab urbe condita). This year has been called 52 BC since the early medieval period, when the Anno Domini calendar era became the most common method in Europe for naming years.
