This thesis analyzes La historia de Rosian de Castilla in terms of its metafictional components and shows how this work is a metafictional antecedent to El ingenioso hidalgo don Quijote de la Mancha. I will define, explain, and comment on metafiction in terms of what it is, when it began, and how it works as a technique in chapter 1. Also, I will discuss Miguel de Cervantes Saavedra in terms of his influence on the later development of metafiction, referencing examples of metafictional episodes in El ingenioso hidalgo don Quijote de la Mancha Volume I and II in chapter 2. Most importantly, I will consider another work as an antecedent to El ingenioso hidalgo don Quijote de la Mancha: La historia de Rosian de Castilla, a work translated (i.e., written) by Joaquin Romero de Cepeda. I will analyze its metafictional aspects as antecedents to El ingenioso hidalgo don Quijote de la Mancha in chapter 3. According to the analysis I offer, La historia de Rosian de Castilla was a precursor to the metafictional technique in El ingenioso hidalgo don Quijote de la Mancha.
