Martín Fierro is a 2,316 line epic poem by the Argentine writer José Hernández. The poem was originally published in two parts, El Gaucho Martín Fierro (1872) and La Vuelta de Martín Fierro (1879). The poem is, in part, a protest against the modernist tendencies of Argentine president Domingo Faustino Sarmiento. As well, the poem supplied a historical link to the gauchos' contribution to the national development of Argentina, for the gaucho had played a major role in Argentina's independence from Spain. The poem, written in a Spanish that evokes rural Argentina, is widely seen as the pinnacle of the genre of "gauchesque" poetry (poems centered around the life of the gaucho, written in a style that evokes the rural Argentine ballads known as payadas) and a touchstone of Argentine national identity. It has appeared in literally hundreds of editions and has been translated into over 70 languages. It has earned major commentaries from, among others, Leopoldo Lugones, Miguel de Unamuno, Jorge Luis Borges (seeBorges on Martín Fierro) and Rafael Squirru.
