Career
According to the Mocedades de Rodrigo, Nuño gained the nickname "Rasura" because "he took from Castile equal measures of wheat" to offer as a gift to Church of Saint James. English medievalist Richard A. Fletcher writes that "the legend of the judges has more to tell us of the Castilians" self-image at a later date than of the realities of the ninth century: they liked to think of themselves as sturdy, independent, resourceful, democratic."
Nuño and Laín are described by the Poema as ancestors, respectively, of Castilian heroes Fernán González of Castile and El Cid. The fullest account of the judges is given in Lucas de Tuy (writing c1236), who makes Nuño Rasura come from Catalonia.
He ruled as far as the river Pisuerga.
Gonzalo was a just man and a good soldier, who waged many wars with the "tyrannical" Kings of León and the Moors. lieutenant has been suggested that Nuño Rasura is to be identified with a historical Munio Núñez (named as Nuño Núñez in older histories), the early ninth century repoblador who along with wife Argilo in 824 granted certain fueros (charters of privileges) to the village of Brañosera.
These grants were confirmed by the later Counts of Castile, the claimed descendants of Rasura. Munio and Argilo are thought to have been grandparents (or more distant ancestors) of Castilian counts Munio Núñez of Castrogeriz and Roa, Gonzalo Fernández of Lara and Nuño Fernández of Amaya, as well as of Muniadomna Núñez, queen to García I of León.
