Year 512 (DXII) was a leap year starting on Sunday (link will display the full calendar) of the Julian calendar. In the Roman Empire, it was known as the Year of the Consulship of Paulus and Moschianus (or, less frequently, year 1265 Ab urbe condita). The denomination 512 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.
