Near the mih-rab there once stood a pulpit constructed by Hakem II., equalled by none other in the world for workmanship and materials. It was built of ivory and the rarest woods, such as ebony, sandal, almond, Indian plantain, citron, aloe, and so forth. This beautiful object was to be seen in the Cathedral of Cordova as late as the middle of the sixteenth century, when it was dismembered and its materials employed in the construction of a Christian altar. It was known to the Spaniards under the name of _carro de Almanzor_, the chariot of Al-mansur--probably because it stood upon wheels. Not only did the Khalif Hakem II. make many additions to the great Mosque of Cordova, but improvements which greatly benefited the city. In place of the old reservoir for purification in the Court of the Mosque, he built four others at two sides of the Mosque, and these he filled by means of a canal which, taking the water from the hills of Cordova, poured it into an immense reservoir of marble which fed the four minor cisterns. These marble receptacles for water may yet be seen in the Mezquita of Cordova; the quarry whence they were extracted is likewise indicated by the peasants at a few miles from the city. The water, running constantly, after supplying the needs of the Mosque, was distributed into three conduits parting from three sides of the Mosque, East, North, and West, thus supplying the city and suburbs. The actual dimensions of the Mosque are difficult to establish. An excellent authority says that in length from North to South, the Mosque measures six hundred and twenty feet, in width four hundred and forty feet. Mr. Waring, in his _Notes of an Architect in Spain_ says the Mosque is an oblong of three hundred and ninety-four feet by three hundred and sixty feet. The famous Orange Court is in length two hundred and twenty feet, and, being within the boundary walls of the Mosque, is probably included in the first measurement given. It is impossible to fix with any degree of certainty the number of columns contained in the Mosque during the time of Mohammedan supremacy. Ambrosio de Morales and the Infante Don Juan Manuel, both of whom described the Mosque before the columns were reduced in number by the unnecessary, not to say barbarous, alterations to which the building has been subjected, estimate the figures at one thousand and twelve; but it is only too certain that when the Mosque was converted into a Christian Church very many columns were removed to make room for altars, chapels, and the like.
