El viaje entretenido not only provides information for the history of theater in Spain, but also, in its peculiar structure, a short and fragmented novel is inserted. The novel is divided into three parts within a very measured organization, in a book where the structure is a rigid scaffolding. Rojas projects in the novel his desires of a cultured author, in open contrast with the dialogue of the four characters that fills the journey. The novel also functions as a break in the narrative on which the four-voice dialogue is based, as a written and rhetorical story in contrast to the conversational tone of the book, as a serious and complex story, as an interrupted tale that recovers the readers' interest when the dialogue between the four traveler characters lapses or has been prolonged, as a literary manifestation of an "author" who also wants to be an author.
