From French fier to bras, brave arm, brabucón. Also mentioned as Fierabrás de Alejandría, Saracen heroic character mentioned in the cantares de gesta of the Carolingian era, sung by the Occitan troubadours, which is also echoed by our Cervantes in Don Quixote. Fierabrás carried on his horse relics of the passion of Christ such as the crown of thorns, nails, INRI and oil to embalm the body that would later become the balm of Fierabrás. What imagination the medieval Christians threw at him in their fight against the Saracens!
