I cannot write an overview based on the context provided, as "year" alone does not contain any specific historical information about 484 BC. Without factual context about what happened in 484 BC or why it matters, I would have to invent details, which violates your instruction to base the overview only on provided context and be accurate.

Year 484 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Mamercus and Vibulanus (or, less frequently, year 270 Ab urbe condita). The denomination 484 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.
