a more powerful, perhaps a more ruthless, oppressor, were certain of tranquillity only in the silence and oblivion of the grave. The advent of Moslem supremacy, which promised a new and splendid career to the down-trodden race, was welcomed by the Jews of Africa with all the enthusiasm of an impulsive and excitable people. Al-Maghreb had scarcely been conquered before the Moslem generals were more conversant with the details of Visigothic weakness and demoralization than the councillors of Roderick himself. The minute and secret ramifications of Jewish society united in a common cause the widely distributed communities of Africa and Spain; the intelligence and resolution of the conspirators, whose hostility was increased by the bitterness of sectarian hatred, rendered their enterprise and activity the more dangerous; and a propitious opportunity alone was awaited to pour upon the fertile and defenceless plains of the Peninsula the resistless torrent of Moslem invasion. That opportunity soon arrived. The fortress of Ceuta, lost by treason, fell into the hands of the Arabs; the Visigothic power, crushed in one great battle, succumbed to the superior valor of an enterprising enemy; and within the short period of fourteen months the sceptre of empire passed from the feeble hands of a barbarian dynasty to the control of a foreign race, whose mental capacity and intellectual ambition, as yet untried, were subsequently found to be equal to the most exacting demands of a refined and highly developed civilization. In these events, whose consequences produced such radical modifications in the religious, political, and domestic conditions of European society, Hebrew energy and craft were eminently conspicuous. One of the principal divisions of Tarik’s army was commanded by a Jew. During the invasion, Jewish guides conducted the Moslem squadrons along the highways of an unknown country, furnished information of the enemy’s movements, disclosed the whereabouts of military supplies and hidden wealth. When the slender numbers of the Arab forces would not admit of their diminution for garrison duty, the Jews volunteered their services to defend the conquered cities and faithfully discharged the important trust. The obligations thus incurred by the Moorish invaders to their allies were of the most important character. The latter not only facilitated an enterprise whose difficulty, without their co-operation, would have been enormously increased, if not actually rendered impracticable, but, the country once subdued, they directed the attention of the Arabs to elegant pursuits, of whose nature and value they had hitherto remained in ignorance. Moslem civilization in Europe owed an incalculable debt of gratitude to the Jews. They were its real founders. They inculcated a taste for letters. They promoted the investigations of science, the development of industry and the arts. Their refined tastes and intellectual employments aroused a
