The Christian church in Cordova stood upon the site of the former Roman religious edifice dedicated to Janus, and upon this situation Abd-er-Rahman desired to rear his great mosque. Autocrat though he was, the monarch strove to maintain the conditions upon which the inhabitants had surrendered. He might have broken faith, and annexed the Christian building and the ground upon which it stood. But he honourably offered to buy the church and the plot from the conquered people. The negotiations of purchase were placed in the hands of the Sultan’s favourite secretary, Umeya Ibn Yezid.
At first the Christians refused to sell their cherished basilica, which had been divided into a temple of the faith of Christ and a fane for the worship of Allah. Here, in separate portions of the building, the conquerors and the conquered murmured their prayers and repeated their praises to their deities. How the Cordovese were induced to relinquish the church cannot be explained by any historical evidence that we are able to obtain from the writings of Arabians and Spaniards. Some authors have suggested that the Christians of Cordova were disheartened by adversity and the assaults of Islam upon their creed, and that they yielded to the suasion and counsels of Umeya Ibn Yezid, and sold their tabernacle to the invaders. At any rate it is manifest that Abd-er-Rahman won in the end, and that he was able to forward his project without showing violence to the natives of Cordova.
No doubt the Christians preferred to worship in their own buildings rather than to share the basilica with the infidels, and this preference may have influenced their spiritual leaders in meeting the request of the sultan and his agent. Under the terms of transference, the Cordovese were permitted to reconstruct the edifice formerly dedicated to St. Faustus, St. Januarius, and St. Marcellus, three martyrs whom they deeply revered. Immediately upon the conveyance of the church and its site to Abd-er-Rahman, the work of erecting the gorgeous mosque was begun with much enthusiasm and at the expenditure of huge sums of money. The Khalif was rich. Besides the treasure wrested from the Goths during the wars, he extracted a tithe upon the produce of the land and on manufactures. A tax was also laid upon every Christian and Jew in Andalusia. Beyond this, the Moorish kings were greatly enriched by the acquisition of the valuable mines of Spain, the quarries of marble, and other sources of wealth. From these revenues Abd-er-Rahman and his successors, Hisham, Abd-er-Rahman II., the greatest of the dynasty and the third of the line—and lastly, the extravagant Al-manzor—lavished heavy sums upon the designing, construction, and costly adornment of the Mosque.
The power of the first Khalif of Cordova was supreme and undisputed. He was the sole spiritual and temporal head of the people, ‘the Commander of the Faithful.’ Subservient to him were the walis who ruled in the provinces. Abd-er-Rahman’s despotism made upon the whole for charity, tolerance, and justice. The accounts of his persecutions have been coloured by pious historians, and bear the stamp of a natural hostility to the conqueror and his religion. One or two of the more accurate Spanish writers assert that, at the most, only forty persons were martyred in Cordova under the Omeyyad sway; and, according to Morales, these victims sought persecution.
To court sufferings at the hands of the Moors was deemed a noble virtue in the breast of the devout Christians. We may recall the story of Santa Teresa of Avila, who, as a child, wandered from the city with her little brother to seek persecution in the country of the infidels. Whatever may be charged against the Khalifs of the family of Omeyya, it cannot be asserted that their policy after the conquest was one of tyrannous subjugation. They undoubtedly levied taxes and imposts upon the Goths, and confiscated their lands, after a campaign of destruction and aggression; but as victors they displayed magnanimity, and sought to heal the wounded spirit of the vanquished.
The attitude of Abd-er-Rahman I. towards the Christian population of Cordova was, therefore, clement and conciliatory. Under his sovereignty there dawned an age of prosperity and advancement. The work of building the resplendent Mezquita employed thousands of artisans and labourers. This vast undertaking led to the development of all the resources of the district. Durable stone and beautifully veined marbles were quarried from the Sierra Morena and the surrounding regions of the city. Metals of various kinds were dug from the soil, and factories sprang up in Cordova amid the stir and bustle of an awakened industrial energy. A famous Syrian architect made the plans for the Mosque. Leaving his suburban dwelling, the Khalif came to reside in the city, so that he might personally superintend the operations, and offer proposals for the improvement of the designs. We are told that Abd-er-Rahman moved about among the workers, directing them during several hours of every day. The monarch was growing old. It was the longing of his heart to witness the final achievement of his great scheme before death overtook him.
In planning the Mosque the architects incorporated a number of Roman columns with choice capitals. Some of the columns were already in the Gothic structure; others were sent from various quarters of Spain as presents from the governors of provinces. Ivory, jasper, porphyry, gold, silver, copper, and brass were used in the decorations. Marvellous mosaics and azulejos were designed. Panels of scented woods were fastened with nails of pure gold, and the red marble columns were said to be the work of God. The primitive part of the building, reared under the direction of Abd-er-Rahman I., was that bordering the Court of Oranges. Later, the immense temple embodied all the styles of Morisco architecture in one noble composition.
The first Khalif of Cordova did not survive to witness the completion of the Mosque. He died in the Alcazar long before the work was finished, and committed the task to his son Hisham. The prince carried on the work with zealous devotion. Upon his father’s death in 788, the building covered only a small part of the ground now occupied by the Mosque and its later additions. Hisham I. built the tower for the muezzin, and the fretted gallery for the women worshippers, and added much to the Zeca, or House of Purification, erected by Abd-er-Rahman.
The Court of Ablutions was laid out by the first Khalif, and occupied the ground of the present Court of Oranges. In constructing the Mosque, the founders adapted the basilica form of building to the new worship. During the Omeyyad dynasty the original building was constantly enlarged and improved, and fresh decorations were added up to the time of Almanzor. Each Khalif vied with his predecessor in beautifying the temple. The pristine building was finished ten years after the planning under Abd-er-Rahman I., that is, during the reign of Hisham I., who conducted the labour with the utmost expedition. Marbles of spotless white were chosen for the innumerable columns. Arrazi, an Arab writer, speaks of the valuable wine-coloured marble, obtained from the mountains of the district, which was much used in embellishing the naves of the Mosques of Cordova and Ez-Zahra.
The solemnity and beauty of the ceremonies in the House of Purification can only be imagined. Every day saw the celebration of the tazamein, or purification of the devout, before entering the holy structure, and six times daily the alicama, or call to prayer, was shouted by the muezzin from the summit of the minaret. No shoes were permitted to defile the sanctuary; the worshippers entered barefooted. From its sacred shadow all Jews were excluded, and restrictions guarded the approach of women, except the privileged royal brides.
