Nuño Rasura

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.

[1] 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.

"[2] The twelfth-century Liber regum and the Poema de Fernán González report that at the end of the ninth century reign of Alfonso II of Asturias (died 842),[3] two judges were named to administer and defend the newly repopulating region that would become Castile.

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 c.1236), who makes Nuño Rasura come from Catalonia.
