The same spirit revived under the successor of Hassan: it was finally quelled by the activity of Musa and his two sons; but the number of the rebels may be presumed from that of three hundred thousand captives; sixty thousand of whom, the caliph's fifth, were sold for the profit of the public treasury. Thirty thousand of the Barbarian youth were enlisted in the troops; and the pious labors of Musa, to inculcate the knowledge and practice of the Koran, accustomed the Africans to obey the apostle of God and the commander of the faithful. In their climate and government, their diet and habitation, the wandering Moors resembled the Bedoweens of the desert. With the religion they were proud to adopt the language, name, and origin, of Arabs: the blood of the strangers and natives was insensibly mingled; and from the Euphrates to the Atlantic, the same nation might seem to be diffused over the sandy plains of Asia and Africa. Yet I will not deny that fifty thousand tents of pure Arabians might be transported over the Nile, and scattered through the Libyan desert: and I am not ignorant that five of the Moorish tribes still retain their _barbarous_ idiom, with the appellation and character of _white_ Africans. V. In the progress of conquest from the north and south, the Goths and the Saracens encountered each other on the confines of Europe and Africa. In the opinion of the latter, the difference of religion is a reasonable ground of enmity and warfare. As early as the time of Othman, their piratical squadrons had ravaged the coast of Andalusia; nor had they forgotten the relief of Carthage by the Gothic succors. In that age, as well as in the present, the kings of Spain were possessed of the fortress of Ceuta; one of the columns of Hercules, which is divided by a narrow strait from the opposite pillar or point of Europe. A small portion of Mauritania was still wanting to the African conquest; but Musa, in the pride of victory, was repulsed from the walls of Ceuta, by the vigilance and courage of Count Julian, the general of the Goths. From his disappointment and perplexity, Musa was relieved by an unexpected message of the Christian chief, who offered his place, his person, and his sword, to the successors of Mahomet, and solicited the disgraceful honor of introducing their arms into the heart of Spain. If we inquire into the cause of his treachery, the Spaniards will repeat the popular story of his daughter Cava; of a virgin who was seduced, or ravished, by her sovereign; of a father who sacrificed his religion and country to the thirst of revenge. The passions of princes have often been licentious and destructive; but this well-known tale, romantic in itself, is indifferently supported by external evidence; and the history of Spain will suggest some motive of interest and policy more congenial to the breast of a veteran statesman. After the decease or deposition of Witiza, his two sons were supplanted
