El Viejo Vizcacha (in the original Old Viscacha) is a character of the Gauchesco poem La vuelta de Martín Fierro (José Hernández , 1879). Taimado, cynical, thief, exploited, liar, and above all great connoisseur of human miseries, he devoted himself to teaching his ways and his experience to the young son of Fierro while he was his tutor. His entire philosophy represents the way of surviving a gaucho without values, which in many ways opposes that of Martín Fierro. See the devil knows by devil but more knows by old.
