The aim of this paper is to understand some meaningful aspects of the Socratic use of Iliad x 224 in Plato's Protagoras and Symposium. In these dialogues the Homeric reference appears in different contexts, but Plato's Socrates applies it in the same way and seems to indicate it as a relevant step for the implementation of the dialectic method. Socrates is not only provoking his interlocutor, but rather making a comparison between the dialogue's scene and the context involving Diomedes and Odysseus' in Iliad x. Ultimately, the use of this reference shows that a dialogical interplay to achieve a common purpose is a precondition for the Socratic dialectic. This previous cooperation between Homeric characters is emphasized by Plato's Socrates and is derived from a specific soul's manifestation.
