In this paper we tackle Plato’s Dialogues from a theatrical and philosophical point of view. We question in this manner the relationship between dialogue – as writing form- and representation – as notion meaning, in a literary work, “to make present”. Starting from the contradiction between theory and use of mimesis in Plato, we analyze the different situations of enunciation of each dialogue, and the different roles played in within by Socrates, in particular as character and as narrator. We end up in a link between both terms that points out the common presence in dialogue and representation of intermediary elements, through which the reader reaches the work. Keywords: dialoguel; representation; Plato; Socrates character; narrator; mimesis
