I cannot write an accurate overview based on the context provided. The context only identifies "231 BC" as a "year" without any historical details about what happened in that year or why it might matter, making it impossible to create a meaningful 2-sentence explanation without inventing facts.
AI-generated from the Wikipedia summary — may contain errors.
Year 231 BC was a year of the 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.
