AI overview
I appreciate your request, but the context provided ("year") is too minimal to write an accurate, informative overview of 490 BC. To avoid inventing facts, I would need specific historical information about what occurred in 490 BC and why it's significant. If you could provide more context or source material about 490 BC, I'd be happy to write the overview based on that information.

The Battle of Marathon
Year 490 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Camerinus and Flavus (or, less frequently, year 264 Ab urbe condita). The denomination 490 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.
