[EN] This thesis explores the pioneering short film of Spanish spoken cinema, El Orador (1928), by Ramón Gómez de la Serna, in the context of the nascent international sound cinema industry through producer Feliciano Manuel Vitores and Hispano Forest Fonofilms. The enigmas surrounding this "unknown" work of art led to a study of every detail about the film, and its resonance with the present. The thesis involved an analysis of the filmic discourse, reviewing the environmental factors surrounding the text, its context and subsequent performance; studying the piece through the author’s literary works and through its socio-political, technological and filmographical ties to Spain in the 1920s. This paper sets the genealogy of the performative conference in Spain in 1928, showing El Orador as the first ever film performance documented in our country. The thesis begins its journey with El Orador through the present day, drawing an intermittent timeline that spans almost a hundred years, crafting a typological mosaic of “oral species” that, in the words of Miguel Molina, continues the legacy of the conference as an artistic genre. This study verifies the heritage and endurance of the ramonian meta-oratory among avant-garde performing artists from the 1950s onward. The thesis is structured in five chapters. The first describes geneal aspects of the author related to his short film and biography. The second focuses on the film’s script, compiling ramonian essays with a similar aesthetic, as well as Ramon’s own trajectory as a lecturer, including a study of the novel Cinelandia and other scenarios he planned. The third chapter covers the creation of the film and its history within the paleosonic film industry and its connection with other short films by F. M Vitores for Cinefón. The four chapter narrates the film’s presentation as performance and its resonance in the current performing arts and a collage of contemporary oral artists. The last chapter details project R. five studies of short film feature by the author. The annexes contain several compilations, on the one hand a selection from the Archive Vitores, and on the other Ramon’s writing about film, images of Ramón's manuscripts, brought together for the first time. The type of research has been mixed: factual, comparative and pursuing links, meaning the initial hypotheses has been confirmed through new data uncovered, and a personal creative proposal has been configured from the main material and applying the practical current movement of art-research. The results achieved include, first and foremost, setting El Orador in its proper place in time, going beyond its anecdotal role and reclaiming its true importance. The assumption of El Orador’s historic contribution has proven to be correct, revealing it as a milestone piece of its time and ours. The study allowed an interpretation of the new oral trend in contemporary art from the use of humor so characteristic of the writer. Finally, the experimental film R. allowed a dialogue between different film eras and a proposal of a type of hybrid creation inspired by Ramon’s own freedom. The key critical and aesthetic points found in the film allow us to view it as an exemplary model in its political, intellectual and creative positioning. TESIS
