 Another contemporary source from outside Sancho's realms refers to him with a title nearly equivalent to the strictly anachronistic "rex Hispaniarium".In his "Historiarium sui temporis libri quinque", the French chronicler Ralph Glaber lists the kings have maintained friendly relations with Robert II of France by sending him gifts and petitioning him for aid.Among them is "Sancio rege Navarriae Hispaniarium".
