A sudden insurrection of the Christians who had taken refuge in the Asturian Mountains, quickened his suspicions, and inspired him with fears of some dangerous conspiracy against his power. In the height of his anxiety, he bethought him of an Arabian sage named Yuza, who had accompanied him from Africa. This son of science was withered in form, and looked as if he had outlived the usual term of mortal life. In the course of his studies and travels in the East, he had collected the knowledge and experience of ages; being skilled in astrology, and, it is said, in necromancy, and possessing the marvelous gift of prophecy or divination. To this expounder of mysteries Alahor applied to learn whether any secret treason menaced his safety. The astrologer listened with deep attention and overwhelming brow to all the surmises and suspicion of the emir, then shut himself up to consult his books and commune with those supernatural intelligences subservient to his wisdom. At an appointed hour the emir sought him in his cell. It was filled with the smoke of perfumes; squares and circles and various diagrams were described upon the floor, and the astrologer was poring over a scroll of parchment, covered with cabalistic characters. He received Alahor with a gloomy and sinister aspect; pretending to have discovered fearful portents in the heavens, and to have had strange dreams and mystic visions. “O emir,” said he, “be on your guard! treason is around you and in your path; your life is in peril. Beware of Count Julian and his family.” “Enough,” said the emir. “They shall all die! Parents and children—all shall die!” He forthwith sent a summons to Count Julian to attend him in Cordova. The messenger found him plunged in affliction for the recent death of his daughter. The count excused himself, on account of this misfortune, from obeying the commands of the emir in person, but sent several of his adherents. His hesitation, and the circumstance of his having sent his family across the straits to Africa, were construed by the jealous mind of the emir into proofs of guilt. He no longer doubted his being concerned in the recent insurrections, and that he had sent his family away preparatory to an attempt by force of arms, to subvert the Moslem domination. In his fury he put to death Siseburto and Evan, the nephews of Bishop Oppas and sons of the former king, Witiza, suspecting them of taking part in the treason. Thus did they expiate their treachery to their country in the fatal battle of the Guadalete. Alahor next hastened to Carthagena to seize upon Count Julian. So rapid were his movements that the count had barely time to escape with fifteen cavaliers, with whom he took refuge in the strong castle of Marcuello, among the mountains of Aragon. The emir, enraged to be disappointed of his prey, embarked at Carthagena and crossed the straits to Ceuta, to make captives of the Countess Frandina and her son.
