440 BC

Year 440 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Macerinus and Lanatus (or, less frequently, year 314 Ab urbe condita). The denomination 440 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.
