Three Romance or Roman languages were spoken in that portion of Spain which remained in Christian hands: in Catalonia and Aragon the Provençal, Catalan, or Limousin; in Asturias, Old Castile, and Leon the Castilian; and in Galicia the Gallego, whence the Portuguese had its origin. The Catalan was almost entirely similar to the Provençal or langue d'oc of Southern France, and the accession of Raymond Berenger, Count of Barcelona, to the throne of Provence in 1092 united the Catalonian and Provençal peoples under one common rule. Provençal, the language of the Troubadours, was of French origin, and bears evidence of its evolution from the Latin of Provincial Gaul. It appears to have been brought into Catalonia by those Hispani who had fled to Provence from Moorish rule, and who gradually drifted southward again as the more northerly portions of Spain were freed from Arab aggression. The political connexion of Catalonia with Provence naturally brought about a similarity of custom as well as of speech, and indeed we find the people of the Catalan coast and the province of Aragon deeply imbued with the chivalry and gallantry of the more northerly home of the Gai Saber. Throughout the whole Provençal-Catalan [4] tract were held those romantic courts of love in which the erotic subtleties of its men and women of song were debated with a seriousness which shows that the art of love had entered into competition with the forces of law and religion, and had, indeed, become the real business of life with the upper classes of the country. Out of this glorification of the relations of the sexes arose the allied science of chivalry, no less punctilious or extravagant in its code and spirit. This spirit of Provençal chivalry gradually found its way into Castile, heightened and quickened the imagination of its people, and prepared the Spanish mind for the acceptance and appreciation of Romantic literature. But at no time was Castilian imagination passively receptive. It subjected every literary force which invaded it to such a powerful alchemy of transmutation that in time all foreign elements lost their alien character and emerged from the crucible of Spanish thought as things almost wholly Castilian.
