Este articulo analiza el cuento Gallera , del escritor sabanero Alejandro Alvarez y se concentra, no solo en las particularidades del proyecto estetico costumbrista, sino tambien en el analisis y la valoracion critica e intertextual de las rinas de gallos tanto en la musica como en la literatura del Caribe colombiano. De este modo, el texto establece una aproximacion entre el relato de Alvarez y obras posteriores como El Coronel no tiene quien le escriba y Cien anos de soledad, de Gabriel Garcia Marquez y El gallo de oro , del mexicano Juan Rulfo. Por ultimo, este trabajo procura ahondar en algunas consideraciones ideologicas y culturales que vinculan a Gallera con una tradicion ancestral enraizada en el Caribe colombiano que se manifiesta tambien en un amplio abanico de piezas musicales de reconocidos compositores. PALABRAS CLAVES Gallistica, proyecto estetico, costumbrismo, oralidad, vallenato sabanero. ABSTRACT This article analyzes the story Gallera, written by Alejandro Alvarez, and it focuses not only on the particularities of the aesthetic costumbrista project (based on people’s customs), but also on the analysis and the critical and inter- textual validity of the roosters’ fights in the music as well as in the literature of the Colombian Caribbean. Hence, this paper establishes an approach between Alejandro Alvarez’s story and later works as No One Writes to the Colonel and One Hundred Years of Solitude, by Gabriel Garcia Marquez, and The Golden Rooster, by the Mexican writer Juan Rulfo. Finally, this article pretends to deepen in certain ideological and cultural considerations that relate Gallera with an ancestral tradition linked to the Colombian Caribbean, fact that is also evidenced in a wide range of musical works of well known composers. KEY WORDS Rooster fight, aesthetic project, costumbrismo (people’s costumes literature), orality, vallenato (Colombian folkloric music from the northern coast).
