Santos Vega was a mythical Argentine gaucho, and invincible[citation needed] payador (a kind of minstrel that competed in singing competitions resembling dialectic discussions), who was only defeated by the Devil himself,[citation needed] disguised as the payador Juan sin Ropa ("John Clothless").
Afterwards, Hilario Ascasubi wrote "Santos Vega o los Mellizos de la Flor", a long poem in which the minstrel narrates the events.
Soon after, Eduardo Gutiérrez published the "Story of Santos Vega and his friend Carmona prosecuted by justice" as a feuilleton.
Rafael Obligado's poem is romanticist, because it emphasizes nature, twilight, nationalism, and the four elements.
They don't follow a chronological order since the first two feature the "ghost" that inhabits the pampas, the fourth tells his last duel with the Devil; and the third one was a later addition in which Santos Vega (alive) interrupts a match of Pato and calls the gauchos to join the May Revolution.
