They are analyzed, in the Leontius' tale, the different techniques through which the author characterizes his central personage; and then, the interventions which are done by the author himself, the meta-literary traits or the commentaries of contents, and some insistent resources as the tale in the tale and the apparitions and revelatory dreams. It is interpreted that, with the declared intention of touching a vast audience, the technique allows to construct a rhetoric ‘etopoiesis' and to interest the audience by using popular resources in accordance with the language; so, then, the tale is good achieved, because the components of the content and formal strategies are employed with efficacy, in attention to the audience and the intentionality of the author.    Se analizan en el relato de Leoncio las diversas técnicas con las que el autor caracteriza a su personaje central y, luego, las intervenciones que el mismo autor realiza, sean metaliterarias o comentarios del contenido, y ciertos recursos insistentes como el relato dentro del relato y las apariciones y sueños reveladores.
