When the empire fell, Spain became the easy prey of northern barbarians, who held the country by the sword, and intermarried but little with its people. To the Goths Spain owes nothing but eclipse and ruin. No books, no inscriptions of Gothic origin survive; the Gongoristic letters ascribed to King Sisebut are not his work, and it is doubtful if the Goths bequeathed more than a few words to the Spanish vocabulary. The defeat of Roderic by Tarik and Mūsa laid Spain open to the Arab rush. National sentiment was unborn. Witiza and Roderic were regarded by Spaniards as men in Italy and Africa regarded Totila and Galimar. The clergy were alienated from their Gothic rulers. Gothic favourites were appointed to non-existent dioceses carrying huge revenues; a single Goth held two sees simultaneously; and, by way of balance, Toledo was misgoverned by two rival Gothic bishops. Harassed by a severe penal code, the Jew hailed the invading Arabs as a kindred, oriental, circumcised race; and, with the heathen slaves, they went over to the conquerors. So obscure is the history of the ensuing years that it has been said that the one thing certain is Roderic's name. Not less certain is it that, within a brief space, almost the entire peninsula was subdued. The more warlike Spaniards, "_Patient of toil, serene among alarms, Inflexible in faith, invincible in arms,_" foregathered with Pelayo by the Cave of Covadonga, near Oviedo, among the Pyrenean chines, which they held against the forces of the Berber Alkamah and the renegade Archbishop, Don Opas. "Confident in the strength of their mountains," says Gibbon, these highlanders "were the last who submitted to the arms of Rome, and the first who threw off the yoke of the Arabs." While on the Asturian hillsides the spirit of Spanish nationality was thus nurtured amid convulsions, the less hardy inhabitants of the south accepted their defeat. The few who embraced Islamism were despised as Muladíes; the many, adopting all save the religion of their masters, were called Muzárabes, just as, during the march of the reconquest, Moors similarly placed in Christian provinces were dubbed Mudéjares.
