 During Antiquity and Middle Ages, the literary texts derive the term Hispania from an eponymous hero named Hispan, who is mentioned for the first time in the work of the Roman historian Gnaeus Pompeius Trogus, in the 1st century BC.Although "Hispania" is the Latin root for the modern name "Spain", substituting "Spanish" for "Hispanicus" or "Hispanic", or "Spain" for "Hispania", should be done carefully and taking into account the correct context.The Estoria de España ("The History of Spain") written on the initiative of Alfonso X of Castile "El Sabio" ("the Wise"), between 1260 and 1274, during the "Reconquista" ('reconquest') of Spain, is believed to be the first extended history of Spain in Old Spanish using the words "España" ("Spain") and "Españoles"("Spaniards") to refer to Medieval Hispania.
