It is said that he himself furnished the plan for this famous edifice, and even worked on it, with his own hands, one hour in each day, to testify his zeal and humility in the service of God, and to animate his workmen. He did not live to see it completed, but it was finished according to his plans by his son Hixem. When finished, it surpassed the most splendid mosques of the East. It was six hundred feet in length, and two hundred and fifty in breadth. Within were twenty-eight aisles, crossed by nineteen, supported by a thousand and ninety-three columns of marble. There were nineteen portals, covered with plates of bronze, of rare workmanship. The principal portal was covered with plates of gold. On the summit of the grand cupola were three gilt balls, surmounted by a golden pomegranate. At night the mosque was illuminated with four thousand seven hundred lamps, and great sums were expended in amber and aloes, which were burnt as perfumes. The mosque remains to this day shorn of its ancient splendor, yet still one of the grandest Moslem monuments in Spain. Finding himself advancing in years, Abderahman assembled in his capital of Cordova the principal governors and commanders of his kingdom, and in presence of them all, with great solemnity, nominated his son Hixem as the successor to the throne. All present made an oath of fealty to Abderahman during his life, and to Hixem after his death. The prince was younger than his brothers, Suleiman and Abdallah; but he was the son of Howara, the tenderly beloved sultana of Abderahman, and her influence, it is said, gained him this preference.
