Diégesis is a word that comes from the Greek "διήγησις" which means "exposition", "story", "explanation"; and it can be defined according to the dictionary of the real Spanish academy as the narrative development of the events that usually occur in a given literary work. Then, based on this meaning, we can say that diegesis is the analysis of those literary, cinematographic, dramatic or story works understood as a logical and temporal continuation of actions and events.
Another important dictionary called "Dictionary of Narratology", states that diegesis can have two possible meanings, which are: "recall, count, opposing to show mainly act in the past tense"; or the second that expresses "the fictitious world, where the situations and events narrated take place". In such a way, the storyteller or narrator is the one who tells the story; therefore it is the delegate to present to the public or reader the thoughts and actions of all the characters. It should be noted that each of the lines of action of the diegesis are time, space and characters.
In remote times, such as that of the scientific philosopher Aristotle and the also Greek philosopher Plato, the meaning of diegesis was opposed to mimesis, this occurred since the diegesis through the image of a narrator, creates a credible fictional world whose agreements can distinguish oneself from those of the authentic world, or even contradict them; consequently in mimesis said agreements of the writing, seek to adhere to social treaties of different kinds. Then it could be said that compared to the diegesis that seeks to originate and follow its own rules; a mimetic text or writing tries to reproduce documented social or natural events
