In ch. 80 of El Victorial, the author, Gutierre Díaz de Games, presents as the youngest son of Edward III of England, in apseudo-historical context, a blind, strong and brave knight “in love”; his soubriquet, “Desired Love” (‘Amor Deseado’),would be taken from a song composed by a poet in his memory, after he died fighting heroically. Everything leads to thinkthat Gutierre Diaz confuses “Desired Love” with John of Luxembourg (1296-1346), the famous blind king of Bohemiawho also died fighting in the battle of Crécy (1346). This article deals with mentions of this royal character, who wasconsidered an exemplary model of chivalry. The allusion to this “Desired Love”, soubriquet and song, could come fromsome French poem or song that Pero Niño could have heard while travelling through France accompanied by his standardbearer,the author of El Victorial. The numerous mentions of other French knights, military men, lovers, and sometimeseven poets show that both, knight and writer, were very familiar with French courtly and poetic milieux.
