Plato never presents himself as a participant in any of the dialogues, and with the exception of the "Apology", there is no suggestion that he heard any of the dialogues firsthand. Some dialogues have no narrator but have a pure "dramatic" form (examples: "Meno", "Gorgias", "Phaedrus", "Crito", "Euthyphro"), some dialogues are narrated by Socrates, wherein he speaks in first person (examples: "Lysis", "Charmides", "Republic"). One dialogue, "Protagoras", begins in dramatic form but quickly proceeds to Socrates' narration of a conversation he had previously with the sophist for whom the dialogue is named; this narration continues uninterrupted till the dialogue's end.
