__NOTOC__
Year '''231 BC''' was a year of the [[Roman calendar|pre-Julian Roman calendar]]. At the time it was known as the '''Year of the Consulship of Matho and Maso''' (or, less frequently, '''year 523 ''[[Ab urbe condita]]'''''). The denomination 231 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.
