Definition: Arcadian refers to a type of culture or tradition from an earlier period in human history, typically around 2500 BCE-450 BCE, but it's used for broad comparison in this context, like describing a culture from another era. The term comes from the Greek ฯฮฑฯฮฌฮดฮฟฯฮน (paradiรณs) which means "before" or "during."
