Homer is an epic poet, whereas Sophocles is a tragic playwright. The difference between their work is that Homer imitates via narration (a story), and Sophocles imitates via actors. Conversely, Aristophanes and Sophocles both imitate through actors on a stage, only Aristophanes imitates comedy and Sophocles tragedy. Thus, according to Aristotle’s argument, Aristophanes and Sophocles are similar since they share the same mode of imitation.
