Unlike comedies, lampoons and tragedies often include actual historical figures. This is not to say that a tragedy is an imitation of a specific person; instead, Aristotle argues that a tragedy is an imitation of a probable action, and since what
has happened is probable, it is fair game for a tragedy. The difference between history and tragedy, Aristotle maintains, is that history expresses what
has happened (including people who have existed) in a given timeframe, whereas tragedy imitates a probable action that
would happen.
