Once more the train moved past the sun-baked walls of the monastery, across the plain to the mountain road that led to the land of bounty and of culture. Late that afternoon Brother Joseph learned from the lips of a herdsman that the beauteous Zahra, flower of all the Moorish race, had gone to Cordova to study music. II Abul Malek once more rode home alone to his castle; but this time as he dismounted at his door he smiled at the monastery below. Four years crept by, during which the Saracen lord brooded over the valley and the monk Joseph went his simple way, rendering service where he could, preaching, by the example of his daily life and his unselfish devotion, a sermon more powerful than his lips could utter. Through it all the Moor watched him carefully, safeguarding him as a provident farmer fattens a sheep for the slaughter. Once a year the father rode southward to Cordova, bringing news with his return that delighted the countryside, news that penetrated even the walls of San Sebastian and filled the good men therein with gladness. It seemed that the maiden Zahra was becoming a great musician. She pursued her studies in the famous school of Ali-Zeriab, and not even Moussali himself, that most gifted of Arabian singers, could bring more tender notes from the lute than could this fair daughter of Catalonia. Her skill transcended that of Al Farabi, for the harp, the tabor, and the mandolin were wedded to her dancing fingers; and, most marvelous of all, her soul was so filled with poetry that her verses were sung from Valencia to Cadiz. It was said that she could move men to laughter, to tears, to deeds of heroism--that she could even lull them to sleep by the potency of her magic. She had once played before the Caliph under amazing circumstances. The Prince of True Believers, so ran the story, had quarreled with his favorite wife, and in consequence had fallen into a state of melancholy so deep as to threaten his health and to alarm his ministers. Do what they would, he still declined, until in despair the Hadjeb sent for Zahra, daughter of Abul Malek. She came, surrounded by her servants, and sang before El Hakkam. So cunningly did she contrive her verses, so tender were her airs, so potent were her fluttering fingers, that those within hearing were moved to tears, and the unhappy lover himself became so softened that he sped to the arms of his offended beauty and a reconciliation occurred. In token of his gratitude he had despatched a present of forty thousand drachmas of gold to the singer, and her renown went broadcast like a flame. When Abul Malek heard of this he praised his God, and, gathering his horsemen, he set out to bring his daughter home, for the time was ripe.
