Where did the history of rhetoric devices and the concepts of ethos, pathos, and logos begin?

Rhetorical appeals refer to ethos, pathos, and logos. These are classical Greek terms, dating back to Aristotle, who is traditionally seen as the father of rhetoric. To be rhetorically effective (and thus persuasive), an author must engage the audience in a variety of compelling ways, which involves carefully choosing how to craft his or her argument so that the outcome, audience agreement with the argument or point, is achieved. Aristotle defined these modes of engagement and gave them the terms that we still use today: logos, pathos, and ethos.
