It might have been an Arab who said "he cared not who made the laws of his country, so he could write its songs." Learning, literature, refinements of luxury and of art had taken possession of the land, which seemed given up to the muses. When in 822 Abd-er-Rahman II. reigned, he did not trouble himself about the laws of his crumbling empire. The one man in whom he delighted was _Ziryab_. What Petronius was to Nero,[A] and Beau Brummel to George IV., that was Ziryab to the Sultan Abd-er-Rahman II., the elegant arbiter in matters of taste. From the dishes which should be eaten to the clothes which should be worn, he was the supreme judge; while at the same time he knew by heart and could "like an angel sing" one thousand songs to his adoring Sultan. Even the Gothic Christians were seduced by these alluring refinements. They felt contempt for their old Latin speech and for their literature, with the tiresome asceticism it eternally preached. The Christian ideal had grown to be one of penance and mortification of the flesh, and to a few ardent souls these sensuous delights were an open highway to death eternal. _Eulogius_ became the leader of this band of zealots. In lamenting the decadence of his people, he wrote, "hardly one in a thousand can write a decent Latin letter, and yet they indite excellent Arabic verse!" Filled with despairing ardor this man aroused a few kindred spirits to join him in a desperate attempt to awaken the benumbed conscience of the Christians. They could not get the Moslems to persecute them, but they might attain martyrdom by cursing the Prophet; then the infidels, however reluctant, would be compelled to behead them. This they did, and one by one perished, to no purpose. The Gothic Christians were not conscience-stricken as Eulogius supposed they would be, and there was no general uprising for the Christian faith. In 912 the threatened ruin of the dynasty was arrested by the coming of another Abd-er-Rahman, third Sultan of that name. Rebellion was put down, and fifty years of wise and just administration gave solidity to the kingdom, which also then became a _Khalifate_. The Abbaside Khalifs, after the deposition of the Omeyyads, had removed the Khalifate from Damascus to Baghdad. But the empire had extended too far west to revolve about that distant pivot. Abd-er-Rahman--perhaps remembering the old feud between his family and the Abbasides--determined to assume the spiritual headship of the western part of the empire. And thereafter, the Mahommedan empire--like the Roman--had two heads, an Eastern Khalif at Baghdad, and a Western Khalif at Cordova.
